Only use marine-grade neutral cure polyurethane sealants. Do NOT use sealants containing acetate or silicone, which can cause damage to plastic parts.

Pre-installation test

Testing the transducer
Transducer operation should be checked before installation.

1. Connect the transducer to the transducer connection of a RealVision™ 3D sonar-capable device (e.g. Axiom RV multifunction display).
2. Fully submerge the transducer in water.
3. Power up the RealVision™ 3D sonar-capable device, and / or multifunction display.
4. Open a Fishfinder (Sonar) application on your multifunction display.
5. If required, select the relevant transducer / channel from the Channel selection page (Menu > Channel).
6. Check that accurate depth and temperature readings are displayed.
7. If you experience difficulties obtaining readings then contact Raymarine Technical Support.

Warning: Transducer operation
Only test and operate the transducer in the water. Do NOT operate out of water as overheating may occur.

Caution: Transducer cable

• Do NOT use the transducer cable to lift or suspend the transducer; always support the transducer body directly during installation.
• Do NOT cut, shorten, or splice the transducer cable.
• Do NOT remove the connector.

If the cable is cut, it cannot be repaired. Cutting the cable will also void the warranty.

Multiple transducers

Note: If you are installing a split-pair of transducers, ensure that you test both transducers together by connecting them to the RealVision™ 3D sonar- capable device (i.e.: MFD or sonar module) using a Y-cable and extension cable.

Refer to the colored “Port” and “Starboard” labels on the cables to ensure that you connect the transducer cables to the correct Y-cable tails.

Selecting a location

Warnings and cautions

Important: Before proceeding, ensure that you have read and understood the warnings and cautions provided in the Chapter 1 Important information section of this document.

Warning: 2 person installation required
To prevent potential product damage, vessel damage and personal injury 2-person installation is recommended.

Location requirements
Follow the guidelines below when selecting a location for your single transducer or split-pair transducers.

For best performance, transducers should be installed in a location with the least turbulence and aeration.

Important:
Do NOT install transducers in-line with trailer rollers, your vessel’s engine intake or discharge openings.

• Transducers should be installed as close to the center line of the vessel as possible.
  

1. Outboard   or I/O (Planing hull) — mount forward and to the side of the propeller(s).
2. Inboard (Planing hull) — mount forward of the propeller(s) and shaft(s).
3. Stepped hull (Planing hull) — mount on the first step as far aft as possible.
4. Displacement hull — mount approximately 1/3 of the way along the length of the hull, measured along the waterline.
5. Fin keel (Keel sailboat) — mount forward of the keel, ensuring that the keel will not obstruct the transducers wide beam width.
6. Full keel (Keel sailboat) — mount away from the keel at a location with minimum dead rise, ensuring that the keel will not obstruct the transducers wide beam width.

• The mounting surface should be flat so that transducer sits flush against the hull.

• When installing split-pair transducers with angled elements, you must ensure that the hull’s deadrise angle at the chosen mounting location is appropriate for the selected transducers.

• When fitting to a hull with a keel, ensure that the transducer beam will not be obstructed by the keel. If the transducer cannot be fitted fore or aft of the keel then use split pair transducers to overcome the obstruction.
  

• The transducers should be installed away from any protrusions such as other transducers, steps, ribs, strakes, or rows of rivets.

• Transducers should be installed in a location where no load will be applied to the transducers during, launching, lifting, trailering and storage of the boat.

• Transducers must be installed in the correct orientation, with the anti-rotation bolt closest to the stern of the vessel. Additionally, a direction arrow pointing to the bow is embossed on the anti-rotation bolt cap.

• When installing split-pair transducers:

  • the correct transducer (port or starboard) must be installed in the matching (port or starboard) side of the hull; each transducer in a split pair has a label on the attached cable, and markings and labels on the transducer body to help you identify the transducer:
    

1. Red — Port-side split-pair transducer cable

2. Green — Starboard-side split-pair transducer cable
   

3. Direction to vessel bow

4. Element angle and vessel side:

   • Single (all-in-one) transducers are marked “0°”
   • Split pair (“12°” or “20°”)
   • Split pair — port, “P” or starboard, “S”)

5. Split pair — Vessel side and direction to vessel keel (Single all-in-one transducers do not include this label.)

• Transducers should be installed in a location where there is sufficient clearance inside the hull to fit the nut and have at least 100 mm (4 in) of headroom to allow for withdrawal.
• To avoid interference with the internal magnetometer, mount transducers at least 1 m (39 inches) from other electrical devices.

Cored fiberglass hull mounting
It is recommended that the transducer is mounted in a non-cored section, if installation in a cored section is required then the area around the hole must be adequately strengthened to ensure it is not damaged when tightening the hull and anti-rotation nuts.

Important: Installation in a cored fiberglass hull should only be carried out by a competent marine installer.

EMC installation guidelines
Raymarine equipment and accessories conform to the appropriate Electromagnetic Compatibility (EMC) regulations, to minimize electromagnetic interference between equipment and minimize the effect such interference could have on the performance of your system

Correct installation is required to ensure that EMC performance is not compromised.

Note: In areas of extreme EMC interference, some slight interference may be noticed on the product. Where this occurs the product and the source of the interference should be separated by a greater distance.

For optimum EMC performance we recommend that wherever possible:

• Raymarine equipment and cables connected to it are:
  • At least 1 m (3.3 ft) from any equipment transmitting or cables carrying radio signals e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance should be increased to 2 m (6.6 ft).
  • More than 2 m (6.6 ft) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element.
• The product is supplied from a separate battery from that used for engine start. This is important to prevent erratic behavior and data loss which can occur if the engine start does not have a separate battery.
• Raymarine specified cables are used.
• Cables are not cut or extended, unless doing so is detailed in the installation manual.

Note:
Where constraints on the installation prevent any of the above recommendations, always ensure the maximum possible separation between different items of electrical equipment, to provide the best conditions for EMC performance throughout the installation.

Transducer dimensions — RV-3xx

Note:
For installations where space behind the display is limited, a right-angled transducer cable adaptor is available (A80515). Using the right angled cable adaptor will reduce dimension P above by 20 mm (0.79 in.)

Transducer mounting

The mounting procedure below should be read thoroughly before attempting to mount the transducer.

Important:

• Only perform the installation with your vessel out of the water.
• Do NOT lift or suspend the transducer using its cable.
• Ensure that the transducer body is supported during installation.
• Do NOT remove the label attached to the transducer cable; as it helps to ensure correct connection.
• Do NOT overtighten the hull nut or anti-rotation bolt. Overtightening can cause damage to the hull which may result in water leaking into the vessel.

Important:
If you are installing the transducer using the High speed nose cone accessory (part number:
A80702) follow the ‘Transducer mounting’ procedure in the documentation supplied with it.

Drilling holes in the hull
To install a Thru-hull transducer, you must drill holes in the hull of your vessel for the transducer stem and anti-rotation bolt.

1. Check the labels on the top of the transducer to confirm that you are using the correct transducer (i.e.: port / starboard, 0°, 12° or 20° tilted element) for your chosen mounting location.

2. Using self-adhesive tape, attach the supplied mounting template to your chosen mounting location. Ensure that the ‘Bow’ arrow on the template is pointed towards the vessel’s bow and that the template is flat and not creased.

3. Mark the hole centers on the hull for the transducer stem and anti-rotation bolt holes, by piercing through the template and marking the hull.

4. Remove the template from the hull.

5. Drill a pilot hole for the transducer stem hole.

6. (1)Drill a 62 mm (229 /64 inch) hole for the transducer stem, using a hole cutter. (Only) if you are installing the optional High speed nose cone accessory (A80702), the transducer stem hole needs to be 70 mm (2 3 /4 inch)
   Important:
   If the specified size hole cutter is not available, use a slightly smaller size hole cutter and then carefully file the hole to the correct size. Alternatively you could use a jigsaw to cut the hole and then carefully file the edge to create a circle the required size.

7. Using a half round file and / or sandpaper, ensure there are no rough edges or burrs around the transducer stem hole.

8. Guide the transducer cable and then the transducer stem up through the transducer stem hole and support from beneath.

9. Ensure that the anti-rotation bolt hole is lined up with the mark, you made on the hull and the transducer is parallel to the centerline of the vessel.

10. Holding the transducer in place, carefully drill the pilot hole for the anti-rotation bolt (using the anti-rotation hole in the transducer as a guide).

11. Remove the transducer from the hull.

12. Drill a 9 mm (⅜ inch) hole for the anti-rotation bolt. (Only) if you are installing the optional High speed nose cone accessory (A80702), the anti-rotation bolt hole needs to be 16 mm (5 /8 inch).

13. Check that the anti–rotation bolt fits through the hole.

Fitting the anti-rotation bolt
The anti-rotation bolt and bolt cap should be fitted as detailed below

1. Wipe the anti-rotation bolt with an appropriate cloth and cleaning agent (for example: isopropyl alcohol), and ensure the surfaces are dry, clean and free from debris.

2. Apply a thick bead of marine-grade sealant around the stem of the anti-rotation bolt, near the head of the bolt.

3. Guide the anti-rotation bolt through the hole in the transducer ensuring that the bolt head is properly seated.
   The anti-rotation bolt hole includes a captive nut cutout to prevent the bolt from turning during tightening.

4. Apply a small amount of marine grade sealant to the inside of the anti-rotation bolt cap.

5. Fit the anti-rotation bolt cap by pressing it firmly into the hole in the transducer.

The embossed “BOW” arrow must be pointing towards the temperature sensor in the base of the transducer.

Fitting the transducer
Follow the steps below to fit the transducer to your hull.

Note:
Ensure that a generous amount of marine-grade sealant is used on all mating parts and that the parts are clean and dry before installation to ensure a long lasting watertight seal is achieved.

Mounting and sealant application

1. Carefully remove all labels from the top face of the transducer.

2. Remove the labels from the top face of the transducer including any residual label glue.

3. Using an appropriate cloth and cleaning agent (for example: isopropyl alcohol), wipe clean ALL surfaces of the supplied components and the mounting location, both outside and inside the hull ensuring that they are free from grease, debris.

4. Apply a thick bead of marine-grade sealant:

5. all over the top face of the transducer so that it is completely covered.

6. all around the bottom part of the threaded section of the transducer stem and the protruding anti-rotation bolt, ensuring that the sealant will protrude approximately 6 mm above the final tightened nuts.

7. all around and inside the transducer stem and anti-rotation holes on the exterior of the hull.

8. Guide the transducer cable through the stem hole in the hull.

9. Guide the transducer stem and anti-rotation bolt up through the holes in the vessel’s hull and support from beneath.

10. From inside the vessel, apply a continuous, thick bead of marine-grade sealant all around the base of the protruding transducer stem and anti-rotation bolt threads.

11. Guide the rubber washer down the transducer cable, and over the threaded section of the transducer stem, ensuring that the rubber washer sits flush on the hull.

12. If necessary, apply additional marine-grade sealant to the transducer stem, above the rubber washer.

13. With the top face pointing upwards, guide the large internal isolator sleeve down the transducer cable and over the transducer stem, ensuring it sits flush on the rubber washer.

16. Remove the cable protector by pulling the 2 tabs away from the back of the hull nut.

17. Apply a thick bead of marine grade sealant to the bottom face of the hull nut.

18. Screw the hull nut onto the transducer stem and tighten by hand.
    Ensure that the hull nut is adequately tightened. You should see the sealant protruding from the edges of all applied surfaces.

19. Place the small washer over the anti-rotation bolt, ensuring it sits flush on the interior of the hull.

20. If necessary, apply additional marine-grade sealant to the anti-rotation bolt above the small washer.

21. Screw the anti-rotation nut onto the bolt and fully tighten, using a suitable sized wrench  (spanner).

22. Secure the hull nut by feeding a piece of locking wire (not supplied) through the holes in the nut and then tightly wrapping around the threaded section as close to the top of the nut as possible. The wire should then be tied to prevent it coming loose.

23. Remove any excess sealant on the outside of the hull and transducer, ensuring a smooth transition between the transducer and hull.

24. Ensure that the marine-grade sealant has fully cured Refer to the sealant manufacturer’s instructions for curing times.

25. Unless local environmental regulations prohibit, apply a water based anti-fouling paint to the bottom face of the transducer, ensuring all of the externally exposed transducer surfaces are coated and the paint overlaps onto the hull.

26. Check for leaks around the transducer immediately upon putting the vessel back in the water.
    Important:
    Do NOT leave your vessel in the water unchecked after installing your transducer. Very small leaks may not be immediately obvious, and considerable bilge water could accumulate over the course of a day, or overnight.

27. Check for leaks at regular intervals after installation until you are satisfied that there are no leaks.

28. Ensure checking for leaks around the transducer is added to your routine vessel maintenance schedule.

Anti-fouling
Where local regulations allow, it is recommended that you coat your transducer using a water-based anti-fouling paint. This will help prevent the build-up of organic growth, which can reduce transducer performance.

Important:

• Before applying water-based anti-fouling paint, check that local environmental rules and regulations do not prohibit the use of anti-fouling paint.
• Never use copper-based anti-fouling paint as this can impact transducer performance.
• Never use ketone-based anti-fouling paint as this can attack the transducer’s plastic, damaging the transducer.
• Paint your transducer using a brush, do not use a spray can or a sponge roller as these methods can cause tiny air bubbles to be incorporated in the paint, which will also reduce transducer performance.
  

The anti-fouling paint should be applied in a thin and even coat covering all externally exposed transducer surfaces.

You should clean your transducer regularly and re-apply anti-fouling paint every 6 months, or sooner depending on how rapidly organic growth builds up.

General cabling guidance

Cable types and length
It is important to use cables of the appropriate type and length.

• Unless otherwise stated only use cables supplied by Raymarine.
• Where it is necessary to use non-Raymarine cables, ensure that they are of correct quality and gauge for their intended purpose. (e.g.: longer power cable runs may require larger wire gauges to minimize voltage drop along the run).

Strain relief
Use adequate strain relief for cabling to ensure that connectors are protected from strain and will not pull out under extreme sea conditions.

Cable shielding
Ensure that cable shielding is not damaged during installation and that all cables are properly shielded.

Caution: Transducer cable

• Do NOT use the transducer cable to lift or suspend the transducer; always support the transducer body directly during installation.
• Do NOT cut, shorten, or splice the transducer cable.
• Do NOT remove the connector.

If the cable is cut, it cannot be repaired. Cutting the cable will also void the warranty.

Cable routing

Cable routing requirements for the transducer cable.

Important:
To avoid interference, the cable must be routed as far away from VHF radio antenna cables as possible.

Important:
The transducer cable’s connector is supplied with a separate locking collar assembly, used to secure the cable firmly to a RealVision™ 3D sonar-capable device (e.g. Axiom RV multifunction display). Ensure that you route the cable all the way to the 3D sonar-capable device before attaching the locking collar.

• Check that the cable is long enough to reach the equipment it will be connected to. If you are installing split-pair transducers, you must use a Y-cable (A80478) along with an extension cable to connect the transducers to your RealVision™ 3D sonar-capable device (e.g. Axiom RV multifunction display).
• Use grommets in any pass-through holes to prevent damage to the transducer cable.
• Secure the cable at regular intervals using cable clips (not supplied).
• Take care not to apply excessive strain to the cable where it leaves the transducer. Where possible, allow the cable to lay naturally as it leaves the transducer, before securing it with cable clips.
• Do not bend the transducer cable beyond its minimum bend radius. This is particularly important at the point where the cable leaves the transducer.
• Any excess cable should be coiled up at a convenient location.

RealVision™ 3D transducer extension cable

For best performance, cable runs should be kept to a minimum. However, for some installations (including all split-pair transducer installations) it may be necessary to extend the transducer cable.

The following optional extension cables are available:

• Real Vision™ transducer extension cable 3 m (9.8 ft) (part number A80475)
• Real Vision™ transducer extension cable 5 m (16.4 ft) (part number A80476)
• Real Vision™ transducer extension cable 8 m (26.2 ft) (part number A80477)

It is recommended that a maximum of two cable extensions are used, with the total cable length (including the transducer’s fitted cable) not exceeding 24 m (78.7 ft).

Attaching the connector locking collar

The supplied cable is provided with a separate locking collar assembly, ensuring that the cable connection is secure.

This procedure describes how to attach the locking collar to the cable connector. The locking collar parts are supplied in a separate bag, in the package with your product.

Important:
Ensure that you route the cable all the way to its destination before attaching the locking collar

1. Slide the locking collar over the end of the connector, then push it towards the cable-end of the connector.
   Important:
   Ensure that the lugs on the locking collar (labelled ‘A’ in the illustration), are closest to the plug-end of the connector.
   

2. Slide the split-ring over the end of the connector, then push it towards the cable-end of the connector.
   Important:
   Ensure that the tabs on the split-ring (labelled ‘B’ in the illustration), are closest to the cable-end of the connector.
   
   The split-ring slides easily for approximately 1 cm (0.39 in) onto the connector, before butting up against the connector moulding.

3. Carefully insert the pointed end of the supplied tool into the split-ring’s gap (labelled ‘C’ in the illustration).
   
   The tool widens the gap in the split ring, enabling the split ring to be pushed further back onto the connector in the following step.
   Important:

   • Always use the supplied tool when attaching the split ring. The split ring may become overstretched and break if you try to attach it without using the tool.
   • A spare split ring is supplied with the locking collar assembly, in case of breakage.

4. Use the tool to gently lever the split ring over the moulding on the connector until it snaps into position approximately 0.5 cm further back towards the cable-end of the connector.
   
   You can now remove the tool. The split-ring stays in position on the connector, but rotates freely.

5. Slide the O-ring (arrowed) over the end of the connector, and ensure that it is seated squarely against the connector moulding, adjacent to the split-ring.
   

6. Slide the locking collar towards the plug-end of the connector, rotating the collar as necessary to ensure that the lugs on the locking collar (labelled ‘D’ in the illustration) pass through the channels (labelled ‘E’) in the split-ring.
   The locking collar slides easily towards the plug-end of the connector, before butting up against the split-ring moulding.

7. Grasp the body of the connector with one hand, then with the other hand, pull the locking collar firmly towards the plug-end of the connector.
   

As you pull the locking collar, it clicks into place over the split-ring. The locking collar stays in position on the connector, but rotates freely.

Making connections

Follow the steps below to connect the transducer cable to a RealVision™ 3D sonar-capable device (for example, Axiom RV multifunction display).

1. Ensure that the vessel’s power supply is switched off.
2. If your installation comprises split-pair transducers:
3. Connect the cable from each transducer to the Y-cable tails (A80478); check the colored labels on the cables to ensure that the transducers are connected to the correct Y-cable tail.
4. Connect an extension cable to the remaining free plug on the Y-cable. See RealVision™ 3D transducer extension cable.
5. Ensuring correct orientation, push the transducer cable (or extension cable) connector fully onto the corresponding connector on the RealVision™ 3D sonar-capable device (for example, Axiom RV multifunction display).
6. Turn the locking collar clockwise to secure the cable.

System checks and troubleshooting

Chapter contents

• 5.1 RealVision™ 3D AHRS calibration on page 40
• 5.2 Troubleshooting on page 40

RealVision™ 3D AHRS calibration

RealVision™ 3D transducers include a built-in AHRS (Attitude and Heading Reference Sensor), which measures the motion of your vessel to assist in the rendering of sonar images. After installation all RealVision™ 3D transducers require calibration.

An uncalibrated transducer can produce an offset to the front edge of the render of the bottom in the sonar image, as illustrated below.

Uncalibrated

Calibrated

Calibration is an automatic process and starts after your vessel has turned approximately 100° at a speed of between 3 –15 knots. Calibration requires no user input, however at least a 270° turn is required before the calibration process can determine the local deviation and apply a relevant offset.
The time it takes to complete the calibration process will vary according to the characteristics of the vessel, the installation environment of the transducer, and the levels of magnetic interference at the time of conducting the process. Sources of significant magnetic interference may increase the time required to complete the calibration process. Certain areas with substantial magnetic deviation may require extra circles or “figure of 8” manoeuvres to be performed. Examples of such sources of magnetic interference include:

• Vessel engines
• Vessel alternators
• Marine pontoons
• Metal-hulled vessels
• Underwater cables

Note:
In some circumstances, it is beneficial to disable Realvision AHRS if local sources of magnetic interference are distorting the sonar image. Realvision AHRS can be disabled from Settings.
Menu > Settings > Sounder > AHRS stabilization

Note:
The Calibration process will require repeating after a Sonar reset or MFD Factory reset.

Transducer cleaning
You must clean your transducer regularly to remove organic growth. Organic growth can build up quickly on the bottom face of your transducer; this can impact transducer performance in a matter of weeks.

Important:

• When cleaning growth from an anti-fouled transducer, take care not to let paint dust and other debris enter the water, as this can have an impact on aquatic life.
• Take care not to scratch the surface of the transducer as this can impact transducer performance.
• Do NOT use harsh cleaning solvents such as acetone as this will damage the transducer.

Follow the guidance below to clean growth from your transducer:

• use a soft cloth and a mild household cleaning detergent to clean mild growth build up.
• use a scouring pad, such as a green Scotch Brite™ pad and a mild household cleaning detergent to clean moderate growth build up.
• you may need to use a fine grade wet and dry paper and a mild household cleaning detergent to clean severe build up.

Re-applying anti-fouling paint
If you have applied anti-fouling paint to your transducer, it is important to re-apply it at least every 6 months, to maintain effectiveness.
Follow the instructions below to re-apply anti-fouling paint.

Important:

• Following environmental best practice, preparation and re-application of the anti-fouling paint should be performed using suitable washdown facilities, which ensures paint particles do not enter the water and impact aquatic life.
• Take care not to scratch the transducer face, as this may impact transducer performance

1. Remove your vessel from the water.
2. Clean your transducer, ensuring all organic growth is removed.
3. Remove any flaking anti-foul paint.
4. Use a soft dry cloth to remove any loose bits of paint.
