How Sonar Works  
Sonar technology is based on sound waves. The HDR 650 Digital Depth Sounder  
uses sonar to determine depth directly below the transducer. Your HDR 650  
Digital Depth Sounder consists of two components: the HDR 650 sonar unit and  
the transducer. The sonar unit contains the transmitter and receiver, as well as  
the user controls and display. The transducer is mounted beneath the water  
surface and converts electrical energy from the transmitter into mechanical  
pulses or sound waves. The transducer also receives the reflected sound waves  
and converts them back into electrical signals for display on the sonar unit.  
Sonar is very fast. A sound wave can travel from the surface to a depth of 240 ft  
(70 m) and back again in less than 1/4 of a second. It is unlikely that your boat  
can "outrun" this sonar signal.

Installation Overview  
Before you start installation, we encourage you to read these instructions  
carefully in order to get the full benefit from your HDR 650 Digital Depth Sounder.  
In addition to the hardware included in the installation kit, you will also  
need the following supplies:  
powered hand drill and various drill bits, including a 2 1/8" hole saw if your  
boat does not have an existing gauge hole  
Phillips-head and flat-head screwdrivers  
ruler or measuring tape  
pen or pencil  
12 Volt power source (your boat's battery)  
marine-grade silicone sealant (for sealing drilled holes)  
two-part, slow-cure epoxy (for inside-the-hull transducer installation only)  
NOTE: If you are wiring directly to the boat's battery, you will also need a 1 Amp  
fuse and a fuse holder.

Installing the HDR 650  
You will install your HDR 650 depth sounder first, then your transducer. When  
you are done with both of these installation tasks, you should perform a final  
installation test before operating your HDR 650. Perform the following high-level  
steps by following the instructions in each numbered section to install the depth  
sounder:  
1. Locating the HRD 650 mounting position  
2. Cutting the mounting hole  
3. Customizing and assembling the HDR 650  
4. Installing the HDR 650  
5. Installing the buzzer  
6. Connecting to the power supply  
7. Installing the transducer  
Installation

1. Locating the HDR 650 Mounting Position  
You must select an appropriate mounting location for the HDR 650. Consider  
different positions on the console or deck of the boat, and note the following:  
The cables for the transducer and power must reach the mounting location.  
Extension cables are available.  
The mounting surface should be visible to the boat operator and adequately  
supported to protect the HDR 650 from excessive wave shock and vibration.  
Allow at least 2" clearance at the back, sides, and top of the unit for  
connection, air flow, and ease of installation and removal.  
Choosing Mounting Hole Location  
2. Cutting the Mounting Hole  
Once you have selected your mounting location, perform the following steps:  
1. Mark the desired mounting location, then drill a pilot hole.  
2. Drill a 2 1/8" diameter hole using a hole saw and hand drill. This is a  
standard hole saw readily available for rental or purchase. If you prefer, any  
marine service shop can perform this task.

3. Customizing and Assembling the HDR 650  
Your HDR 650 includes a variety of face plates and trim rings so that you can  
customize the appearance.  
1. Select one face plate and one trim ring.  
2. Peel off the protective backing from the face plate. Be careful not to let the  
adhesive touch anything prematurely.  
CAUTION: In order to provide a lasting, waterproof bond, the face plate adhesive  
is extremely sticky, and you will NOT be able to re-position it once you have stuck  
it onto the face of the HDR 650.  
3. Carefully line up the face plate with the face of the HDR 650. Press the face  
plate into place so that all keys are accessible and the display is visible (see  
illustration).  
4. Align the inside tabs of the trim ring with the HDR 650 tabs, and snap the  
trim ring onto the front of the HDR 650 (see illustration).

5. Installing the Buzzer  
Securing the Buzzer  
Secure the buzzer to a nearby wire bundle  
using the cable ties (included).  
Buzzer  
6. Connecting to the Power Supply  
Use the following information to connect your HDR 650 to an appropriate power  
supply:  
• If your boat has an electrical system, there is probably a fuse panel in the  
console area that can be used to attach the HDR 650 power cable.  
• If a fuse terminal is available, use crimp-on type electrical connectors (not  
included) that match the terminal on the fuse panel. Attach the black wire  
to ground and the red wire to 12 VDC power. You must use a 1-Amp fuse in  
the connection.  
• 36" of power cable is included; you may shorten or lengthen this cable using  
18-gauge, multi-strand copper wire.

GROUND  
Inline Fuse Holder  
CAUTION: Some boats have 24 or 36 Volt electrical systems. Make sure that your  
HDR 650 is connected to a 12 VDC power supply. Use a voltage conditioner for  
variable inputs.  
NOTE: Humminbird® is not responsible for over-voltage or over-current failures. The  
control head must have adequate protection through the proper selection and  
installation of a 1 amp fuse.  
1a. If a fuse terminal is available, use crimp-on type electrical connectors (not included) that  
match the terminal on the fuse panel. Attach the black wire to ground (-), and the red wire  
to positive (+) 12 VDC power. Install a 1 amp fuse (not included) for protection of the unit.  
Humminbird® is not responsible for over-voltage of over-current failures.  
or...  
1b. If you need to wire the HDR 650 directly to a battery, obtain and install an inline fuse  
holder and a 1 amp fuse (not included) for the protection of the unit. Humminbird® is not  
responsible for overvoltage or overcurrent failures.  
7. Installing the Transducer  
Proceed to Transducer Installation Overview for installation instructions. Before  
you start installation, we encourage you to read the instructions carefully so that  
you may understand the installation requirements.

Transducer Installation Overview  
Find the correct section for your transducer installation type. If you have a  
transom mount transducer, you can mount it on the transom (preferred), in the hull,  
or you can purchase the trolling motor adapter and mount it on your trolling motor.  
The included transducer is designed for transom mounting on the boat (directly  
exposed to the water). On fiberglass hull boats, this same transducer can be  
bonded to the inside of the hull. When mounted inside the hull, the sonar signal  
actually passes through the hull of the boat. One of these two mounting  
techniques will produce acceptable results on most boats. There are, however,  
several situations that may demand a different type of transducer. Inboard boats,  
wood or metal hulls, and sailboats often have unique transducer mounting  
requirements.  
Transducer Installation Overview

Transom Transducer Installation  
1. Locating the Transducer Mounting Position  
NOTE: If transom mounting is not possible because of a stepped hull or cavitation  
noise, and you have a single layer fiberglass hull, In-hull installation is an option.  
See Inside the Hull Transducer Installation for more information.  
Turbulence: You must first determine the best  
location on the transom to install the transducer. It  
is very important to locate the transducer in an area  
that is relatively free of turbulent water. Consider  
the following to find the best location with the least  
amount of turbulence:  
Areas of Possible Turbulence  
• As the boat moves through the water,  
turbulence is generated by the weight of the  
boat and the thrust of the propeller(s) - either  
clockwise or counter-clockwise. This turbulent  
water is normally confined to areas immediately  
aft of ribs, strakes or rows of rivets on the bottom  
of the boat, and in the immediate area of the  
propeller(s). Clockwise propellers create more  
turbulence on the port side. On outboard or  
inboard/outboard boats, it is best to locate the  
transducer at least 15" to the side of the  
propeller(s) (see the illustration Turbulence-  
Free Location).  
Rivets  
Transom  
Strakes  
Hull  
Stepped Hull  
Rib  
Step  
• The best way to locate turbulence-free water is  
to view the transom while the boat is moving.  
This method is recommended if maximum high-  
speed operation is a high priority. If this is not  
possible, select a location on the transom where  
the hull forward of this location is smooth, flat  
and free of protrusions or ribs (see the  
illustration Areas of Possible Turbulence).  
Transom Mount Transducer Installation

• On boats with stepped hulls, it may be possible to mount the transducer  
on the step. Do not mount the transducer on the transom behind a step  
to avoid popping the transducer out of the water at higher speeds; the  
transducer must remain in the water for the control head to maintain  
the sonar signal (see the illustration Stepped Hull).  
• If the transom is behind the propeller(s), it may be impossible to find an area  
clear from turbulence, and a different mounting technique or transducer  
type should be considered, such as an Inside the Hull Transducer.  
• If you plan to trailer your boat, do not mount the transducer too close to  
trailer bunks or rollers to avoid moving or damaging the transducer during  
loading and unloading of the boat.  
• If high speed operation is critical, you may want to consider using an In-Hull  
transducer instead of this Transom Mount transducer.  
Turbulence-Free Location  
Level  
15”  
Find a turbulence-free location at least 15” from the propeller(s) and not in  
line with trailer bunks or rollers.  
NOTE: The hydrodynamic shape of your  
transducer allows it to point straight down  
without deadrise adjustment.  
Deadrise Angle  
NOTE: If you cannot find a transom mount location that will work for your high-  
speed application, find an In-Hull Transducer by contacting our Customer  
Resource Center at either 1-800-633-1468 or by visiting our Web site at  
humminbird.com.

2. Preparing the Mounting Location  
In this procedure, you will determine the mounting location and drill two  
mounting holes, using the transducer mounting bracket as a guide.  
1. Make sure that the boat is level on the trailer,  
both from port to starboard and from bow to  
stern, by placing your level on the deck of the  
boat, first in one direction, then in the other.  
Positioning the  
Mounting Bracket  
Level  
2. Hold the mounting bracket against the  
transom of the boat in the location you have  
selected. Align the bracket horizontally, using  
the level; make sure that the lower corner of  
the bracket does not protrude past the bottom  
of the hull, and there is at least 1/4" clearance  
between the bottom of the bracket and the  
bottom of the transom for fiberglass boats, and  
1/8" clearance for aluminum boats (see the  
illustration Boat Hull Types Require Different  
Mounting Positions).  
Boat Hull Types Require  
Different Mounting Positions  
NOTE: If you have a flat-bottomed aluminum  
boat, some additional adjustment may be needed  
to accommodate the rivets on the bottom of the  
boat (i.e. the gap may need to be a little smaller  
than 1/8"). This will help you to avoid excessive  
turbulence at high speeds.  
1/4” for fiberglass  
1/8” for aluminum  
NOTE: If your propeller moves clockwise (in  
forward, as you're facing the stern of the boat  
from behind), mount the transducer on the  
starboard side, and align the bottom right corner  
of the mounting bracket with the bottom of the  
boat. If your propeller moves counter-clockwise  
(in forward, as you're facing the stern of the boat  
from behind), mount the transducer on the port  
side, and align the bottom left corner of the  
mounting bracket with the bottom of the boat.

Using the Mounting Bracket  
to Mark the Initial Drill Holes  
3. Continue to hold the bracket on the transom of  
the boat, and use a pencil or marker to mark  
where to drill the two mounting holes. Mark the  
drill holes near the top of each slot, making sure  
that your mark is centered in the slot (see the  
illustration Using the Mounting Bracket to  
Mark the Initial Drill Holes).  
4th hole  
NOTE: The third hole should not be drilled until  
the angle and height of the transducer is finalized,  
which you will not do until a later procedure.  
Mark Initial  
3rd hole  
Drill Holes  
4. Make sure that the drill bit is perpendicular to the  
actual surface of the transom, NOT parallel to the  
ground, before you drill. Using a 5/32” bit, drill the  
two holes only to a depth of approximately 1”.  
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce  
the chance of chipping or flaking the outer coating.  
3. Assembling the Transducer and Initial Mounting  
In this procedure, you will assemble the transducer using the hardware provided,  
then mount it and make adjustments to its position without locking it in place.  
NOTE: You will initially assemble the transducer and the pivot arm by matching the  
two ratchets to a numbered position on the transducer knuckle. Further adjustments  
may be necessary.  
1a. If you already know your transom angle, refer to the chart below for the  
initial position to use to set the ratchets. If your transom is angled at 14  
degrees (a common transom angle for many boats) use position 1 for the  
ratchets. In either case, go to step 2. If you do not know your transom  
angle, go to step 1b.

Measuring the Transom Angle  
1b. If you do not know your transom angle,  
measure it using a plumb line (weighted  
nylon string or monofilament line) exactly 12  
inches long. Hold the top of the plumb line  
against the top of the transom with your  
finger, and wait until the line hangs straight  
down. Using a ruler, measure the distance  
from the bottom of the plumb line to the  
back of the transom, then use the chart.

2. Place the two ratchets, one on either side of the transducer knuckle, so  
that the beads on each ratchet line up with the desired position number  
on the knuckle (see the illustration Transducer Knuckle Positions). If you  
are setting the ratchets at position 1, the beads on each ratchet will line  
up with the rib on the transducer knuckle to form one continuous line on  
the assembly (see the illustration Ratchets Placed in Position 1).  
NOTE: The ratchets are keyed; make sure that the square teeth on each ratchet  
face the square teeth on the transducer knuckle, and the triangular teeth face  
outward.  
Hold the ratchets on the transducer knuckle with one hand and fit the pivot  
arm over them until it snaps into place with the other hand. Refer to the  
illustration Fitting the Mounting Bracket Over the Ratchet.

3. Put the pivot bolt through the assembly to  
hold it in position and loosely install the nut,  
but do NOT tighten the nut at this time (see  
the illustration Inserting the Pivot Bolt).  
Insert the pivot arm assembly into the  
mounting bracket (see the illustration  
Inserting the Pivot Arm Assembly Into the  
Mounting Bracket). Do NOT snap the  
assembly closed, as you will need to access  
the mounting bracket in the next step.  
Inserting the Pivot Bolt  
NOTE: If the pivot assembly is snapped closed over the mounting bracket, use a flat  
head screwdriver or similar tool to gently pry the assembly away from the  
mounting bracket (see the illustration Prying the Assembly Away from the  
Mounting Bracket).

6. Adjust the initial angle of the transducer from back to front by rotating the  
transducer until the side seam on the transducer is almost parallel with the  
bottom of the boat, one click at a time in either direction (see the  
illustration Adjusting the Initial Transducer Angle).

7. Adjust the transducer assembly vertically, until the seam on the leading edge  
of the transducer (the edge closest to the transom of the boat) is level and  
just slightly below the hull (see the illustration Adjusting the Transducer  
Mounting Position).  
NOTE: The transducer has a natural downward slant of 4-5 degrees from leading  
edge (closest to the boat transom) to trailing edge (farthest away from the boat).  
Looking at the back of the transducer, the seam should be slightly below the  
bottom of the hull.  
8. Continue to adjust until the bracket is also level from port to starboard  
(horizontally level as you look at the transducer from behind the boat (see  
the illustration Leveling the Mounting Assembly Horizontally).

10. Tighten the pivot bolt, using the pivot screw and nut to lock the assembly.  
Hand tighten only!  
11. Snap open the assembly and hand-tighten the two mounting screws, then  
snap the assembly closed.  
NOTE: You will drill the third mounting hole and finalize the installation after you  
route the cable and test and finish the installation in the following procedures.  
4. Routing the Cable  
The transducer cable has a low profile connector, which must be routed to the  
point where the control head is mounted. There are several ways to route the  
transducer cable to the area where the control head is installed. The most  
common procedure routes the cable through the transom, into the boat.  
NOTE: Your boat may have a pre-existing wiring channel or conduit that you can  
use for the transducer cable.  
1. Unplug the other end of the transducer cable from the control head (if it  
is already connected). Make sure that the cable is long enough to  
accommodate the planned route by running the cable over the transom.  
Transom Mount Transducer Installation  
Download from Www.Somanuals.co1m8. All Manuals Search And Download.  
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the  
cable insulation. Route the cable as far as possible from any VHF radio antenna  
cables or tachometer cables to reduce the possibility of interference. If the cable is  
too short, extension cables are available to extend the transducer cable up to a total  
of 50'. For assistance, contact the Customer Resource Center at humminbird.com  
or call 1-800-633-1468 for more information.  
NOTE: The transducer can pivot up to 90 degrees in the bracket. Allow enough  
slack in the cable for this movement. It is best to route the cable to the side of the  
transducer so the transducer will not damage the cable during movement.  
2a. If you are routing the cable over the transom of  
the boat, secure the cable by attaching the  
cable clamp to the transom, drilling 9/64"  
diameter holes for #8 x 5/8" wood screws, then  
skip directly to procedure 5, Connecting the  
Cable.  
Routing the Cable  
or...  
2b. If you will be routing the cable through a hole  
in the transom, drill a 5/8" diameter hole  
above the waterline. Route the cable through  
this hole, then fill the hole with marine-grade  
silicone sealant and proceed to the next step  
immediately (see the illustration Routing the  
Cable).  
3. Place the escutcheon plate over the cable hole  
and use it as a guide to mark the two  
escutcheon plate mounting holes. Remove the  
plate, drill two 9/64" diameter x 5/8" deep  
holes, and then fill both holes with marine-  
grade silicone sealant. Place the escutcheon  
plate over the cable hole and attach with two  
#8 x 5/8" wood screws.

4. Route and secure the cable by attaching the cable clamp to the transom;  
drill one 9/64" diameter x 5/8" deep hole, then fill hole with marine-grade  
silicone sealant, then attach the cable clamp using a #8 x 5/8" screw.  
Storing Excess Cable  
NOTE: If there is excess cable that needs to be  
gathered at one location (as shown in the  
illustration), dress the cable routed from both  
directions so that a single loop is left extending from  
the storage location. Doubling the cable up from this  
point, form the cable into a coil. Storing excess cable  
using this method can reduce electronic interference  
(see the illustration Storing Excess Cable).  
5. Connecting the Cable  
If you unplugged the transducer cable at the beginning of this procedure, plug it  
back into the depth sounder.  
NOTE: The connector is keyed to prevent reverse installation, so be careful not to  
force the plug into the connector the wrong way.  
6. Test and Finish the Installation  
Once you have installed both the HDR 650 and the transom transducer, and have  
routed all the cables, you must perform a final test before locking the transducer  
in place. Testing should be performed with the boat in the water although you  
can initially confirm basic operation with the boat out of the water.  
1. Turn on the power source to power up the HDR. If the unit does not power  
up, make sure that the connector holder is fully seated in the receptacle  
and that power is available.  
2. If all connections are correct and power is available, the Humminbird®  
control head will enter Normal operation.  
3. If the digital depth readout displays on the screen, the unit is working  
properly. Make sure that the boat is in water greater than 2' but less than  
the depth capability of the unit, and that the transducer is fully submerged,  
since the sonar signal cannot pass through air.

NOTE: The transducer must be submerged in water for reliable transducer  
detection.  
4. If the unit is working properly, gradually increase the boat speed to test  
high-speed performance. If the unit functions well at low speeds, but  
begins to skip or miss the bottom at higher speeds, the transducer requires  
adjustment.  
5. If you have the correct angle set on the transducer, yet lose a bottom  
reading at high speed, adjust the height and the running angle in small  
increments to give you the ideal transducer position for your boat. First,  
adjust the height in small increments (see the illustration Adjusting the  
Transducer Mounting Position).

NOTE: The deeper the transducer is in the water, the more likely that a rooster tail  
of spray will be generated at high speeds, so make sure that the transducer is as  
high as it can be and still be submerged in the water.  
If you are still not getting good high speed readings, you may need to  
disassemble the transducer mounting assembly and re-position the ratchets  
(see the illustrations Transducer Knuckle Positions, Ratchets Placed in  
Position 1, Ratchets Placed in Position 2, and Fitting the Mounting  
Bracket Over the Ratchet).

If you do change the transducer position, re-trace the position of the mounting  
bracket before proceeding.  
NOTE: It is often necessary to make several incremental transducer adjustments  
before optimum high speed performance is achieved. Due to the wide variety of  
boat hulls, however, it is not always possible to obtain high speed depth readings.  
6. Once you have reached a consistently good sonar signal at the desired  
speeds, you are ready to lock down the transducer settings. Force the pivot  
to the Up position to gain access to the mounting screws, then re-align the  
mounting bracket against the transom of the boat to match the traced  
silhouette. Check the bracket position with the level again to make sure it  
is still level, then mark the third mounting hole using a pencil or marker.  
Unscrew and remove the mounting screws and the transducer assembly  
and set aside.

7. Drill the third mounting hole, using a 5/32” drill bit. Use a marine-grade  
silicone sealant to fill all three drilled mounting holes, especially if the holes  
penetrated the transom wall.  
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce  
the chance of chipping or flaking the outer coating.  
8. Re-position the transducer assembly against  
the transom of the boat, then hand-install all  
three screws. Make sure that the transducer  
location and the pivot angle have not  
changed, then fully tighten all three mounting  
screws (see the illustration Fully Tighten All  
Three Mounting Screws). Snap the pivot  
back down. If you have performed the  
preceding procedures correctly, the  
transducer should be level and at the right  
height for optimal operation.

7. Locking Down the Transducer (Optional)  
NOTE: You have the option to lock down the Two Piece Kick Up bracket if you do  
not want the transducer to kick up. Please be aware, however, that the transducer  
can be damaged if it is locked down and it strikes debris in the water.  
Using the Mounting Bracket  
to Mark the Initial Drill Holes  
1. To lock down the transducer, trace the  
position of the mounting bracket. Force the  
pivot to the Up position to gain access to the  
mounting screws, then re-align the mounting  
bracket against the transom of the boat to  
match the traced silhouette. Check the  
bracket position with the level again to make  
sure it is still level, then mark the fourth  
mounting hole using a pencil or marker (see  
the illustration Using the Mounting Bracket  
to Mark the Initial Drill Holes). Unscrew and  
remove the mounting screws and the  
transducer assembly and set aside.

2. Drill the fourth mounting hole, using a 9/64"  
drill bit. Use a marine grade silicone sealant to  
fill all four drilled mounting holes, especially if  
the holes penetrate the transom wall.  
Locking the Pivot Arm  
3. Re-position the transducer assembly against  
the transom of the boat, then hand install the  
first three screws (two on the outside edges  
and one in the 3rd mounting hole). Make sure  
that the transducer location and the pivot  
angle have not changed, then fully tighten all  
three mounting screws (see the illustration  
Fully Tighten All Three Mounting Screws).  
Hand-tighten only! Snap the pivot back down.  
4. Install #8 x 1" wood screw into the 4th hole to  
lock down the pivot arm (see the illustration  
Locking the Pivot Arm). Hand-tighten only!

Inside the Hull Transducer Installation  
In-hull mounting generally produces good results in single-thickness  
fiberglass-hulled boats. Humminbird® cannot guarantee depth performance  
when transmitting and receiving through the hull of the boat, since some  
signal loss occurs. The amount of loss depends on hull construction and  
thickness, as well as the installation position and process.  
WARNING! This installation requires slow-cure two-part epoxy. Do not use  
silicone or any other soft adhesive to install the transducer, as this material  
reduces the sensitivity of the unit. Do not use five-minute epoxy, as it has a  
tendency to cure before all the air bubbles can be purged, thus reducing signal  
strength.  
NOTE: In-hull mounting requires an installed and operational depth sounder.  
1. Locating the Transducer Mounting Position  
Decide where to install the transducer on the inside of the hull. Consider the  
following to find the best location:  
• Observe the outside of the boat hull to find the areas that are mostly free  
from turbulent water. Avoid ribs, strakes and other protrusions, as these  
create turbulence.  
• As a general rule, the faster the boat can travel, the further aft and closer to  
the centerline of the hull the transducer has to be located in order to remain  
in contact with the water at high speeds.  
Inside the Hull Transducer Installation  
Download from Www.Somanuals.co2m5. All Manuals Search And Download.  
2. Trial Installation  
You will not be able to adjust the mounting after an inside the hull transducer is  
installed. It is best, therefore, to perform a trial installation first that includes  
running the boat at various speeds, in order to determine the best mounting area  
before permanently mounting the transducer.  
1. Plug the transducer into the depth sounder, then power up the depth  
sounder. When the depth sounder detects a functioning transducer, it will  
automatically enter Normal operating mode.  
Positioning the Transducer  
Preferred Mounting Area  
2. View the sonar signal at its best by holding the transducer over the side,  
immersed in the water, so that it is pointing straight down over a known  
flat bottom. Use the display to benchmark against the sonar signal that  
will be detected once the transducer is placed in the hull.  
3. Place the transducer body face down at the identified mounting location  
inside the hull, with the pointed end towards the bow (see the illustrations  
Positioning the Transducer and Preferred Mounting Area).  
Inside the Hull Transducer Installation  
Download from Www.Somanuals.co2m6. All Manuals Search And Download.  
4. Fill the hull with enough water to submerge the transducer body. Use a  
sand-filled bag or other heavy object to hold the transducer in position. The  
transducer cannot transmit through air, and the water purges any air from  
between the transducer and the hull, and fills any voids in the coarse  
fiberglass surface.  
5. View the sonar signal on the display and compare against what was  
observed in Step 2, making sure that the boat is in the same location as it  
was during your observations in Step 2. If the results are comparable, move  
on to Step 6. Otherwise, locate a new position in the hull and repeat Steps  
3 through 5.  
6. Run the boat at various speeds and water depths while observing the  
screen on the depth sounder. If depth performance is required, test the  
transducer in water at the desired depth. If the performance is acceptable,  
move on to Step 7. If the performance is not acceptable, repeat Steps 3  
through 6.  
7. Once you have determined the best mounting location using the above  
steps, mark the position of the transducer.  
3. Routing the Cable  
1. Once the mounting location is determined and you have marked the  
position of the transducer, route the cable from the transducer to the depth  
sounder.  
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the  
cable insulation. Route the cable as far as possible from any VHF radio antenna  
cables or tachometer cables to reduce the possibility of interference. If the cable is  
too short, extension cables are available to extend the transducer cable up to a total  
of 50' (15 m). For assistance, contact the Customer Resource Center at  
humminbird.com or call 1-800-633-1468 for more information.

4. Permanently Mounting the Transducer  
NOTE: Once permanently mounted, you will not be able to make further  
adjustments to the transducer.  
1. Make sure the position of the transducer is  
marked.  
Coating the Transducer with Epoxy  
2. Remove the water from inside the hull and  
thoroughly dry the mounting surface. If  
the surface is excessively rough, it may be  
necessary to sand the area to provide a  
smooth mounting surface.  
3. Mix an ample quantity of two-part slow  
cure epoxy slowly and thoroughly. Avoid  
trapping air bubbles.  
4. Coat the face of the transducer and the  
inside of the hull with epoxy (see the  
illustration Coating the Transducer with  
Epoxy).  
Pressing the Transducer Into Place  
5. Press the transducer into place with a  
slight twisting motion to purge any  
trapped air from underneath, keeping the  
pointed end of the transducer body  
pointed forward, towards the bow (see the  
illustration Pressing the Transducer Into  
Place).  
NOTE: Proper operation requires the  
pointed end of the transducer body to face  
towards the bow.  
6. Weight the transducer so that it will not move while the epoxy is curing.  
NOTE: When the epoxy cures, no water is necessary inside the hull.

7. If you unplugged the transducer cable at the beginning of this procedure,  
plug it back into the depth sounder.  
NOTE: The connector is keyed to prevent reverse installation, so be careful not  
to force the plug into the connector the wrong way.  
NOTE: Neither water, spilled gasoline, nor oil will affect the performance of the  
transducer.  
Trolling Motor Transducer Installation  
Several styles of the transducer are compatible  
with trolling motor mounting. If you have a  
trolling motor bracket, refer to the separate  
installation instructions that are included with  
the bracket.  
Trolling Motor Transducer Options  
If you don’t have a trolling motor transducer, there are several options:  
• You may purchase a Trolling Motor Adapter kit that will allow you to mount  
the transducer on the trolling motor.  
• You may also exchange your NEW and UNASSEMBLED transducer (with  
mounting hardware included) for a trolling motor transducer.  
NOTE: There are also several transducer switches available that support the  
configuration of two depth sounders with one transducer or two transducers with  
one depth sounder.  
NOTE: Call the Humminbird® Customer Resource Center at 1-800-633-1468 for  
details and pricing, or visit humminbird.com for more information.

Operating the HDR 650  
Your HDR 650 Digital Depth Sounder sends a sound wave signal and determines  
distance by measuring the time between the transmission of the sound wave and  
when the sound wave is reflected off of an object. As your HDR 650 transducer  
receives sonar signals, it converts them to a digital depth that is shown on the  
HDR 650 display. The depth reading is continuously updated as you travel across  
the water. The liquid crystal display (LCD) offers sharp viewing, even in bright,  
direct sunlight, and is continuously lit for nighttime operation.  
NOTE: Actual depth capability depends on such factors as bottom hardness, water  
conditions, and transducer installation. Units will typically read to deeper depths in  
fresh water than in salt water.  
The HDR 650 Control Head  
The HDR 650 uses a backlit display, together with a 3-button keypad, to control

Maintenance  
To keep both your HDR 650 and your transducer working properly, perform the  
following maintenance tasks as needed.  
HDR 650 Maintenance  
If your HDR 650 unit comes into contact with salt spray, simply wipe the affected  
surfaces with a cloth dampened in fresh water. Do not use a chemical glass  
cleaner on the lens, as chemicals in the solution may cause cracking in the lens.  
When cleaning the LCD protective lens, use a chamois and non-abrasive, mild  
cleaner. Do not wipe while dirt or grease is on the lens. Be careful to avoid  
scratching the lens.  
WARNING: Never leave your HDR 650 in a closed car or trunk; the extremely high  
temperatures generated in hot weather can damage the electronics.  
Transducer Maintenance  
If your boat remains in the water for long periods of time, algae and other marine  
growth can reduce the effectiveness of the transducer. Periodically clean the face  
of the transducer with hot water. Pivoting the transducer up in the bracket may  
allow better access for inspection or cleaning.  
If your boat remains out of the water for a long period of time, it may take some  
time to wet the transducer after it is returned to the water. Small air bubbles can  
cling to the surface of the transducer and interfere with proper operation. These  
bubbles will dissipate with time, or you may wipe the face of the transducer with  
your fingers after the transducer is in the water.

Troubleshooting  
Before contacting the Humminbird® Customer Resource Center, please read the  
following section. Taking the time to review these troubleshooting guidelines may  
allow you to solve a performance problem yourself, and therefore avoid sending  
your unit back for repair.  
NOTE: Do not attempt to repair the HDR 650 yourself, as there are no user-serviceable  
parts inside, and special tools and techniques are required for reassembly in order to  
maintain the waterproof integrity of the housing. Repairs should be performed only by  
authorized Humminbird® technicians.  
HDR 650 Doesn't Power Up  
If your HDR 650 doesn't power up, refer to the Installation section, and make  
sure that:  
• the power cable is properly connected to the HDR 650;  
• the power cable is wired correctly, with red to positive battery terminal and  
black to negative terminal or ground;  
• the fuse is operational; a fuse can often appear to be good when in fact it  
is not; check the fuse with a tester or replace it with a known good fuse;  
• if the unit is wired through a fuse panel, make sure that the panel is  
powered, as accessory fuse panels are often controlled by a separate  
switch, or even the ignition switch of the boat;  
• the battery voltage of the power connector is between 10 and 20 VDC.  
Correct any known problems, including removing corrosion from the battery  
terminals or wiring, or actually replacing the battery if necessary.  
Troubleshooting

No Bottom Reading on the Display  
If there is no bottom reading visible on the display, there are a number of possible  
causes for this condition, including:  
• if the loss of bottom information occurs only at high boat speeds, then a  
transducer adjustment may be needed (refer to the Transducer Installation  
section);  
• check the transducer cable connection on the back of the HDR 650 and  
make sure that the cable to the transducer has not been cut or pinched, as  
even a small abrasion in the cable can affect performance significantly.  
Correct any known problems, including adjusting the transducer, or actually  
replacing the transducer cable if necessary.  
No Continuous Depth Display in Very Shallow Water  
Losing continuous depth when the boat is in very shallow water is normal,  
because the automatic range control cannot lock onto the bottom in depths of  
one foot or less.  
Screen Fades, Images are not Sharp  
If the screen begins to fade, and images are not as sharp as normal, check the  
input voltage. The HDR 650 will not operate on input voltages below 10 VDC.  
Bottom Reading Disappears During a Hard Turn  
Losing the bottom reading temporarily when the boat is executing a hard turn is  
normal, as the transducer emerges from the water during such a turn; this  
condition should correct itself once the turn is completed.

ENVIRONMENTAL COMPLIANCE STATEMENT: It is the intention of Humminbird®  
to be a responsible corporate citizen, operating in compliance with known and  
applicable environmental regulations, and a good neighbor in the communities where  
we make or sell our products.  
WEEE DIRECTIVE: EU Directive 2002/96/EC “Waste of Electrical and Electronic  
Equipment Directive (WEEE)” impacts most distributors, sellers, and manufacturers  
of consumer electronics in the European Union. The WEEE Directive requires the  
producer of consumer electronics to take responsibility for the management of  
waste from their products to achieve environmentally responsible disposal during  
the product life cycle.  
WEEE compliance may not be required in your location for electrical & electronic  
equipment (EEE), nor may it be required for EEE designed and intended as fixed or  
temporary installation in transportation vehicles such as automobiles, aircraft, and  
boats. In some European Union member states, these vehicles are considered  
outside of the scope of the Directive, and EEE for those applications can be  
considered excluded from the WEEE Directive requirement.  
This symbol (WEEE wheelie bin) on product indicates the product must not  
be disposed of with other household refuse. It must be disposed of and  
collected for recycling and recovery of waste EEE. Humminbird® will mark  
all EEE products in accordance with the WEEE Directive. It is our goal to  
comply in the collection, treatment, recovery, and environmentally sound disposal  
of those products; however, these requirements do vary within European Union  
member states. For more information about where you should dispose of your  
waste equipment for recycling and recovery and/or your European Union member  
state requirements, please contact your dealer or distributor from which your  
product was purchased.
