WARNING!!!!
This depth sounder should not be used as a navigational aid to prevent
grounding, boat damage, or personal injury. Always operate the boat
at slow speeds in unfamiliar water, or if you suspect shallow water or
submerged objects, as water depth may change too quickly to allow
time for you to react.
TRANSDUCER SELECTION
The transducer supplied with the DF1000D is suitable for installation and operation on most boats. For optimal perform-
ance the transducer should be mounted to the transom of the boat as per the installation instructions supplied with the
transducer installation instructions. On fiberglass hulls (non-cored) and some aluminum hulls it can be glued to the inside
of the hull, but this type of installation will reduce the performance of the DF1000D slightly.
Some boats may require a specialized transducer. If after completely reviewing the transducer installation instructions supplied with
the transducer you find that the supplied transducer is not appropriate for your vessel, please contact NMP at 888-667-2767, or visit
us on the internet at www.norcrossmarine.com for exchange information. You may exchange your new and unused transducer for
another type, but keep in mind that some transducers may have additional costs. Included

IMPORTANT!!!!
Install the transducer before
installing the display to ensure that
the transducer cable is long enough
to reach your desired mounting
location. Read ALL the instructions
completely before proceeding with
the installation.
DISPLAY INSTALLATION
Installation of the DF1000D Display
1. Find a location on the boat that will allow clear viewing of the LCD Display. Please
keep in mind that the wires for the transducer and power must reach the mounting
location.
2. After finding the right location for the display, mark a 2-inch hole.
3. Check behind the desired mounting location for any cables or wiring which could be
damaged, then cut out the 2-inch hole and seal any exposed wood with a marine
sealant.
4. Insert the display from the front of the panel, and install the bracket and locking nut
from the rear of the panel (see Figure 1). Make sure that the face of the display is
rotated upright and aligned to your satisfaction for easy viewing from the vessel’s
helm.
The DF1000D can also be surface mounted using NMP’s exclusive MB01 Adjustable
Surface Mount Bracket (see Figure 2). Please see your local retailer, or contact NMP’s
by phone
888-667-27637 , or online at: www.norcrossmarine.com for purchase

Installing the Face and Bezel
1. Place the face over the display (Figure 3B) making sure to line up the cut outs on the face with
the notches on the display.
2. While holding the bezel (Figure 3A) place it over the display and turn counterclockwise until the
bezel locks into place.
Wiring of the Power Cable
The DF1000D has no ON/OFF switch. Therefore, you will need to wire it to a power source that
will turn the unit on as power is applied. The Key Switch or an ON/OFF power switch will be suit-
able for powering the DF1000D.
1. Connect the BLACK wire to the negative (-) battery terminal or suitable ground (see Figure
4).
2. Connect the RED wire to a positive (+) 12 Volt switchable power source (key switch, on/off
switch) (see Figure 4).

the display and press together as per figure Figure 5.
Figure 5
OPERATING THE DF1000D
The DF1000D’s auto-ranging, auto-sensitivity features means that you never have to worry about adjustments. Simply turn the
power on, and your ready to go. The DF1000D emits sound signals that travel through water, and then calculates the amount of
time that elapsed while the signal traveled down to the bottom and returned back to the transducer. This time is calculated by the
DF1000D and displayed as a depth reading. Extremely dirty water, very soft bottom, high speeds, deep water, or a combination of
the above will result in incomplete or inaccurate readings. Under these conditions variable readings or “- - -” (Figure 6) will be dis-
played.
Setting the Units of Measure
The UNITS of measure for depth readout and alarm functions can be set in 4 easy steps. The two settings available are Feet
(FT) and Meters (M).
To Set the Units:
1. Press and hold the "UP" and "DOWN” keys at the same time for 5 seconds until the units indicator (FT or M) blinks (Figure
7).
2. To set the units to FEET press the “UP” key. “FT” will flash on the Display.
3. To set the units to METERS press the “DOWN” key. “M” will flash on the Display.
4. The display will return to the normal operation mode automatically after five seconds.
Setting the Shallow Water Alarm

TROUBLESHOOTING
There are no user repairable parts within the DF1000D. Attempting to repair the unit yourself
will only void the warranty. If you have a problem with your DF1000D, consult the following trou-
bleshooting guide. If this does not remedy your problem, please contact NMP at 888-667-2767
for assistance.
The DF1000D does not turn on.
1. Check the inline fuse located on the main power supply to the unit. If it is blown, replace it with a 1 amp, normal blow fuse. Clean all corrosion from
the fuse housing, and replace the fuse holder assembly if necessary.
2. Check the power cable connection. Be sure that the unit is connected to a known power source: RED wire to positive, BLACK wire to negative or
ground.
3. Ensure that the power source is powered using a test light, or some other reliable form of testing 12 volt power.
4. If you are sure that the unit is receiving power and is still not turning on, please refer to the warranty and service section.
The Bottom Reading is Random, Flashing, or Appears as “---” on the display.
1. The depth is less than 2.5 feet or greater than 200 feet. Operate the unit under normal operating specifications and check to see if it operating prop-
erly.
2. If this condition occurs only at certain speeds, then a transducer adjustment is needed. Refer to the “Helpful Hints for Transducer Installation” sec-
tion below. Refer to the Transducer Installation Instructions for adjustment procedures.
3. Under certain circumstances the DF1000D may not perform at the best of its ability. Extremely dirty water, very soft bottom, high speeds, deep
water, or a combination of the above will result in incomplete or inaccurate readings. Please refer to the Transducer Installation Instructions to min-
imize the effects of these conditions.
4. If the transducer is transom mounted check to make sure that the transducer is not “kicked-up”. To prevent damage to the transducer, it will auto-
matically release from the mounting bracket (kick-up) when it is impacted. If this occurs refer to the Transducer Installation Instructions to reset the
transducer for normal operation. If this happens frequently make sure that the trailer or boat lift supports do not interfere with the transducer during
loading and unloading.
5. Check the transducer cable connection on the back of the unit. Make sure that the connection is made as per the instructions in the Connecting the
Transducer section of this manual.
6. Contact NMP at 888-667-2767 for assistance if you are unable to correct the problem.
Helpful Hints for Transducer Installation (Transom Mounting)
1. Make sure the transducer is not mounted in any area where the water flow is interrupted by propeller turbulence or
aerated water. If standing at eye level, behind the transducer and looking forward along the bottom of the boat hull
there should NOT be any strakes, chimes, steps, or hull fittings inline with the transducer. If there are any of these
obstructions, the transducer will need to be relocated to achieve optimal performance. The transducer CAN NOT be
transom mounted on a Stepped-Hull vessel, it must only be in-hull mounted.
2. Make sure that the leading edge (bow - side closest to the bow of the boat) of the transducer extends at least 1/8” (3
mm) below the bottom of the hull. Also make sure that the trailing edge (stern - side furthest from the bow of the boat)
is 1/16” to 1/18” (1-3 mm) below the leading edge (Figure 11)
releasing the key will change the value in 1-foot increments per second. Holding down the key will change the value in 9 foot increments per second.
3. After your selection is made, the unit will return to normal operation after 5 seconds.
4. The " "and " " icons will now be present
When triggered, the alarm sounds an audible "alarm" for ten seconds while flashing the warning LED and the " "and “ “ icons on the display. After
10 seconds the audible alarm mutes and the warning LED and the " " and " " icons continue to blink until the depth increases, or the alarm is reset.
To reset the alarm repeat step 1 thru 4.
Setting the Keel Offset
The Keel Offset feature is used to adjust the depth readings displayed by the DF1000D to compensate for the depth of the water required for your ves-
sel to operate safely.
For Example: If your boat’s draft is 3 feet, the Keel Offset feature should be set to 3 feet. The DF1000D will then sub-
tract 3 feet from the actual depth reading, and display this figure as the depth. If the water depth is 5 feet and the Keel
Offset is set to 3 feet, the depth will be displayed as 2 feet, indicating to the operator that there is 2 feet of safe operating
water.
The maximum Keel Offset setting is 20 FT (6.1 M), settable in .1 (1/10th) Foot or Meter increments. The DF1000D will read
“---” when a negative value occurs due to the Keel Offset Subtraction.
To set the KEEL OFFSET:
1. Press and hold the “UP” and “DOWN” keys at the same time for 3 seconds. When “K/O” begins flashing in the upper
left hand corner of the display, release the keys. (see figure 10)
. Press the "UP” key to increase the Keel Offset value. Press the "DOWN" key to reduce the value.
3. The display will return to the normal operation mode after five seconds if no keys are pressed.
4. “K/O” will remain illuminated in the top left hand corner indicating that the depth readings are adjusted to the Keel Offset setting.
WARNING!!!!
If you are unsure of the Draft of your vessel, please consult with the vessel’s manufacturer
before setting the Keel Offset. An improper Keel Offset setting can cause accidently ground-
ing of the vessel and may cause severe damage to the vessel and it’s passengers.

Helpful Hints for Transducer Installation (In-Hull Mounting)
1. The hull must be made out of solid fiberglass or a maximum 1/8” (3 mm) aluminum. The unit will not work through wood, plastic, or any other com-
posite material.
2. The glue in location must be in direct contact with the water at all times during operation. The transducer CAN NOT be mounted in any area where
the water flow is interrupted by propeller turbulence or aerated water. It MUST NOT be mounted behind any strakes, chimes, steps, or hull fittings
that will disrupt the flow of clean water to the transducer (in line with the mounting location of the transducer and the bow of the boat). If there are
any of these obstructions, the transducer will need to be relocated to achieve optimal performance.
3. If mounting in-hull on a stepped hull vessel, the transducer must be mounted in a location where there are no steps forward of the transducer (between
the transducer mounting location and the bow of the boat). Keep in mind that the glue in location must be in direct contact with the water at all times
during operation or incorrect depth readings will occur.
The Transducer Cable Supplied with the Transducer is Too Short for My Installation, Can It Be Extended
YES: To extend the transducer cable:
1. Using a wire cutter, cut the cable on the transducer side 3” (76 mm) from the plug and the cable on the display side 1” (25 mm) from the plug.
2. At both cuts, strip back the rubber cable cover 1” (25 mm) exposing the three internal wires (blue, white, and bare).
3. Using a soldering iron, solder the desired length extension cable (available at a boating supply store or by calling 888-667-2767) between the depth
sounder display and the transducer. Be certain that the blue, white and bare wires are connected properly between the depth sounder display and
the transducer and make sure the colors are consistantly matched throughout the splice.
4. Using electrical tape, or heat shrink tubing make certain that the soldered connections are completely sealed and protected against accidental elec-
trical interference.

Does the Installation Vessel Have These Characteristics?
1. Outboard, inboard/outboard, single inboard, or jet-drive propulsion.
2. Hull deadrise angle below 30°.
3. Transom angle from 3-20°.
Mounting Location
Toobtain the best performance, the transducer should be mounted in a loca-
tion where the water flow is aeration and turbulence-free. Try to mount the
transducer as close to the centerline of the boat as possible.
•On a single drive boat mount on the starboard side at least 4” (101 mm)
beyond the radius of the propeller (see Figure 1 above).
•On a twin drive boat mount the transducer between the drives making cer-
tain that the transducers not directly in front of either drive or propeller.
•On an inboard boat mount the transducers far to the port or starboard as
possible so that the propeller turbulence does not effect the performance
of the sensor.
The MT01 Transom/In-Hull Transducer is suitable for installation and operation on most boats. For
optimal performance the transducer should be mounted to the transom of the boat as per the instal-
lation instructions. On fiberglass hulls (non-cored) and some aluminum hulls it can be glued to the
inside of the hull, but this type of installation will reduce the performance of the depth sounder slight-
ly.
Some boats may require a specialized transducer. If after completely reviewing the transducer installation
instructions you find that the supplied transducer is not appropriate for your vessel, please contact NMP at
888-667-2767, or visit us on the internet at www.norcrossmarine.com for exchange information. You may
exchange your new and unused transducer for another type, but keep in mind that some transducers may
have additional costs.
IMPORTANT!!!!
Install the transducer before installing the display to
ensure that the transducer cable is long enough to
reach your desired mounting location. If the transduc-
er cable needs to be extended, please follow the
instructions in the Troubleshooting Guide before start-
ing the installation.
Read ALL the instructions completely before pro-
ceeding with the installation.
TRANSOM MOUNTING THE TRANSDUCER
CAUTION!!!!
Do not mount the transducer in an area of turbulence or bubbles:
•Near water intake or discharge openings.
•Behind strakes, struts, fittings or hull irregularities.
•Behind eroding paint, hull deformities, or marine growth
Avoid mounting the transducer where the boat may be supported
during trailering, launching, hauling, or storage.
NOTICE!!!!
If the answer to any of these questions is no, skip to the In-Hull
Mounting Instructions within this manual or call 888-667-2767
to inquire about exchanging the transducer.

Assembling and Mounting
1. With the Locking Tab in the up position, align the transducer and bracket as per Figure 2 and slide the trans-
ducer into the Pivot Bracket until it cannot slide any further. (minimal force is required)
2. Press the Locking Tab down against the Pivot Bracket until it locks firmly into place.
3. Tape the template inserted in this manual against the hull as per Figure 3.
4. At the desired mounting location, position the template so the arrow at the bottom is aligned with the bottom
edge of the vessel making certain that the template is parallel to the waterline of the vessel.
5. Using a 9/64" (4 mm) drill bit, drill two holes 7/8" (22 mm) deep at the locations indicated on the template
marked with an “X”. To prevent drilling too deeply, wrap masking tape around the bit 7/8” (22 mm) from the
point. To minimize surface cracking on fiberglass hulls use a chamfer or countersink bit. If either is not avail-
able, start drilling with a 1/4” (6 mm) bit to a depth of 1/16" (1 mm), then finish the hole with the 9/64” (4mm)
bit.
6. Apply a marine sealant to the threads of the two #10 x 1-1/4" self-tapping screws and screw the bracket to
the hull. DO NOT tighten the screws completely until you position the transducer as per the next section.
Positioning
The bracket is designed for a standard 13°transom angle. To determine if the plastic shim is needed, posi-
tion the transducer at the desired location. Using a straight edge, compare the underside of the transducer rela-
tive to the underside of the hull. The stern (trailing edge) of the transducer should be 1/16” – 1/8" (1 – 3 mm)
below the bow (leading edge) of the sensor.
Cable Routing
Route the transducer cable over the transom, through a deck or splash-well drain hole or through a new hole drilled in the transom.
1. If a new hole is required, it MUST be drilled well above the waterline.
2. Mark the desired location with a pencil
3. Check for obstructions behind the desired location inside the hull.
4. Drill a hole through the transom using a 3/4” or 19 mm hole saw or spade bit.
5. Route the cable over or through the transom.
6. On the outside of the hull secure the cable against the transom using the included cable clamps. Evenly distribute the clamps between
the transducer and the location where the cable passes through or over the hull and mark the location with a pencil (Figure 6).
7. At the marked locations, use a 1/8" (3 mm) bit to drill a hole 3/8” (10 mm) deep. To prevent drilling too deeply, wrap masking tape around
the bit 3/8"
8. Apply marine sealant to the threads of the 2 #6 x 1/2" self-tapping screws, position the two cable clamps and fasten them in place. (skip
to #13 if the cable was routed over the transom or a hole that was already in the hull)
9. If a hole has been drilled in the transom position the clam shell cover over the cable where it enters the hull and mark the two screw
holes.
10. Use a 3 mm or 1/8" bit to drill a hole 10 mm (3/8") deep. To prevent drilling too deeply, wrap masking tape around the bit 10 mm (3/8")
from the point of the bit.
11. Fill the remaining space in the hole with marine sealant.
12. Apply marine sealant to the 2 #6 x 1/2" self-tapping screws and fasten the cable clam shell cover into place.
13. Route the cable to the depth sounder to the mounting location of the depth sounder . To reduce electrical interference, separate the transducer cable
from other electrical wiring. Coil any excess cable and secure it in place using tie-wraps.
14. Refer to the depth sounder owner’s manual to connect the transducer to the instrument.

Antifouling Paint
Marine growth can accumulate rapidly on the transducer’s surface. If the vessel is left in saltwater for extended periods of time, all components of the
transducer below the waterline must be painted with WATER BASED antifouling paint.
• Never use ketone-based paint, as this type of paint can damage to the transducer’s plastic shell.
• Clear, spray on antifouling paints are very easy to apply and can be purchased from your local boating supply store.
• Reapply paint as needed to prevent marine growth.
Testing
1. Become familiar with the depth sounders function and performance at idle speeds.
2. Gradually increase the boat speed and observe performance of the depth sounder.
4. If the performance improves when turning, the sensors position probably needs adjustment
because it is in aerated water.
5. Move the transducer farther down on the transom.
6 .If the performance does not improve, move the transducer closer to the centerline making sure
to fill any unused screw holes with marine sealant.
Applications
•High Speed Boats to increase the performance of the depth sounder.
•Trailer boats to prevent accidental damage to the transducer from trailering.
•Shallow draft boats to prevent accidental damage to the transducer to from intentional or unintentional ground.
•NON-CORED hulls or Aluminum Hulls thinner than 1/8”
Hull Material
Since the hull absorbs acoustic energy, transmitting through the hull
reduces the transducers performance. Fiberglass hulls are often reinforced
in places for added strength. These cored areas contain balsa wood or
structural foam which are poor sound conductors. To achieve optimal per-
formance, find a location where the hull laminate is solid (not cored).
Location
Consult the boat manufacturer for the best in-hull transducer placement. If
this information is unavailable, follow the guidelines below and see Figure
7.
•Outboard powerboats - Install as close to the stern as possible
•Inboard / outboard powerboats - Install close to the engine(s)
•Inboard powerboats - Install forward of the propeller(s) and shaft(s)
•Sailboats - Install near the centerline of the hull and forward of the
leading edge of the keel
Testing at the Selected Location
•Place the boat into a body of water where the depth is generally known
(you may also consider using a stick to hang the transducer over the
side of the vessel to develop known depth readings).
• While the boat is anchored, use one of the methods below in Figure 8
to test the depth sounder with the transducer at the desired in-hull
location.
• If the test readings noticeably differ from the known depth you will need
to find another location.
• If the readings are similar mark the spot in the hull and proceed to
Selecting the Adhesive.
FIGURE 8A
•If the hull surface is not smooth, sand it with 30 grit sandpaper until a
smooth surface is obtained. Partially fill a thin plastic bag with water, place the transducer inside and close it tightly with a tie wrap. Wet the surface
of the hull and press the transducer face against it through the bag.
FIGURE 8B
•If the transducer will be located in an area in the hull that holds water, place the transducer
against the hull and allow bilge water to cover the surface where the transducer touches the hull.
FIGURE 8C
•If the hull surface is not smooth, sand it with 30 grit sandpaper until a smooth surface is obtained.
Coat the face of the transducer with petroleum jelly and press it against the hull with a twisting
motion. Use duct tape to hold it in place.

IMPORTANT!!!!
High Speed performance of the depth sounder
may require extensive adjustment and testing to
find the best transducer mounting location. This
transducer has been tested to perform up to 63
MPH in a transom mount application. Not all boat
hull configuration will allow for this type of perform-
ance. If you are not satisfied with the performance
of the depth sounder, it is recommended that you
seek the advice of a professional marine electron-
ics installer.

IMPORTANT!!!!
If you do not get satisfactory depth readings, try
different locations inside the hull. If you cannot
obtain a satisfactory reading using these methods,
you will not be able to mount the tranducer in-hull
on your vessel. Please contact NMP at 888-667-
2767 for transducer exchange information.

Gluing In Place
1. All surfaces to be bonded must be smooth, clean and dry. If the hull surface is not smooth, sand it with 30
grit sandpaper until a smooth surface is obtained in an area a little larger in diameter than the length of the
transducer.
2. Clean and dry both the selected area and the face of the transducer with a weak solvent to remove any dust,
grease or oil.
3. Prepare the adhesive as per the directions supplied with the adhesive.
4. Apply a generous amount of adhesive to the center of the face of the transducer (side opposite from the cable).
5. Press the transducer face onto the hull with a twisting motion to expel all air bubbles. (If the hull is slanted, temporarily secure the transducer in place
with duct tape.) Allow the adhesive to cure as per the manufacturer’s instructions.
6. After the adhesive has cured, route the cable to the depth sounder mounting location. To reduce electrical interference, separate the transducer cable
from other electrical wiring and coil and secure the excess cable in place using tie-wraps.
The Depth Reading on the Depth Sounder is Random, Flashing, and Inconsistent
1. Operate the unit under normal operating specifications and check to see if it operating properly (pay attention to minimum and maximum depth capabil-
ities).
2. If this condition occurs only at certain speeds, then a transducer adjustment is needed. Refer to the “Helpful Hints for Transducer Installation” section
below. Refer to the Transducer Adjustment Instructions for adjustment procedures.
3. Under certain circumstances sonar may not perform at the best of its ability. Extremely dirty water, very soft bottom, high speeds, deep water, or a
combination of the above will result in incomplete or inaccurate readings. Please refer to the Transducer Adjustment Instructions to minimize the effects
of these conditions.
4. If the transducer is transom mounted check to make sure that the transducer is not “kicked-up”. To prevent damage to the transducer, it will automati-
cally release from mounting bracket (kick-up) when it is impacted. If this occurs refer to the Transducer Installation Instructions to reset the transducer
for normal operation. If this happens frequently make sure that the trailer or boat lift bunks do not interfere with the transducer during loading and unload-
ing.
5. Check the transducer cable connection on the back of the depth sounder. Make sure that the connection is made as per the instructions supplied with
the depth sounder.
6. Contact NMP at 888-667-2767 for assistance if you are unable to correct the problems.
Helpful Hints for Transducer Installation (Transom Mounting)
1. Make sure the transducer is not mounted in any area where the water flow is interrupted by propeller turbulence or aer-
ated water. If standing at eye level, behind the transducer and looking forward along the bottom of the boat hull there
should NOT be any strakes, chimes, steps, or hull fittings inline with the transducer. If there are any of these obstruc-
tions, the transducer will need to be relocated to achieve optimal performance. The transducer CAN NOT be transom
mounted on a Stepped-Hull vessel, it must only be in-hull mounted.
2. Make sure that the leading edge (bow - side closest to the bow of the boat) of the transducer extends at least 1/8” (3
mm) below the bottom of the hull. Also make sure that the trailing edge (stern - side furthest from the bow of the boat)
is 1/16” to 1/18” (1-3 mm) below the leading edge.
Helpful Hints for Transducer Installation (In-Hull Mounting)
1. The hull must be made out of solid fiberglass or a maximum 1/8” (3 mm) aluminum. The unit will not work through wood, plastic, or any other compos-
ite material.
2. The glue in location must be in direct contact with the water at all times during operation. The transducer CAN NOT be mounted in any area where the
water flow is interrupted by propeller turbulence or aerated water. It MUST NOT be mounted behind any strakes, chimes, steps, or hull fittings that will
disrupt the flow of clean water to the transducer (in line with the mounting location of the transducer and the bow of the boat). If there are any of these
obstructions, the transducer will need to be relocated to achieve optimal performance.
3. If mounting in-hull on a stepped hull vessel, the transducer must be mounted in a location where there are no steps forward of the transducer (between
the transducer mounting location and the bow of the boat). Keep in mind that the glue in location must be in direct contact with the water at all times
during operation or incorrect depth readings will occur.
The Transducer Cable Supplied with the Transducer is Too Short for My Installation, Can It Be Extended
YES: To extend the transducer cable:
1. Cut the cable on the transducer side 1” (28 mm) from the plug. If the depth sounder display also has a plug, you will need to cut this plug off as well.
2. At both cuts, strip back the rubber cable cover 1” (28 mm) exposing the three internal wires (blue, white, and bare).
3. Using a soldering iron, solder the desired length extension cable (available at a boating supply store or by calling 888-667-2767) between the depth
sounder display and the transducer. Be certain that the blue, white and bare wires are connected properly between the depth sounder display and the
transducer and make sure the colors are consistantly matched throughout the splice.
4. Using electrical tape, or heat shrink tubing make certain that the soldered connections are complete-
ly sealed and protected
against accidental electrical interference.

Selecting the Adhesive
Use a viscous slow-cure epoxy or a fairly rigid, one part adhesive sealant. In cold climates, a one-part polyurethane adhesive, such as Boat-Life’s
Life Seal‚ may be best. Do not use “5 minute” epoxies because they are generally brittle. RTV (silicone) adhesives (Weather Sealants, “Rubbery”
Caulks, 3M 5200, etc) are not recommended because most of the sound energy is lost.
