HD-ID / ClearVü 4 pólusú HD átvilágító műanyag merülőszonda

This Garmin transducer integrates two main sonar technologies:

Traditional HD-ID sonar: Operating on 77/200 kHz frequencies, it effectively displays fish arches and tracks the bottom with precision.ClearVü™ sonar: Operating on 455/800 kHz frequencies (CHIRP 435-475 kHz and 800-840 kHz), it provides near-photographic images of submerged structures and fish beneath the boat.

The transducer has a power output of 500 W for each integrated technology. It can reach the following maximum depths:

Up to 579 meters (1,900 feet) with traditional HD-ID sonar (77/200 kHz).Up to 228 meters (750 feet) with ClearVü™ sonar (455/800 kHz).

Yes, this Garmin transducer has a built-in temperature sensor for measuring water temperature.

This Garmin transducer has a 4-pin connector, ensuring a secure connection to your compatible device.

The transducer is made of plastic, making it suitable for installation on the transom of most boats.

This transom-mounted depth sounder is compatible with hulls of all materials. It is particularly well-suited for towed boats. However, it is not recommended for sailboats due to excessive heel, nor for deep-V hulls.

Yes, this transducer is designed to work with Garmin devices (chartplotters or fishfinders) that support HD-ID and ClearVü™ sonar technologies and have a 4-pin connection port.

For installation on the transom, you will need the following tools:

A #2 Phillips screwdriver. A drill. 4 mm (5/32 in), 3.2 mm (1/8 in), and 16 mm (5/8 in) drill bits for the 4-pin cable. Masking tape. Marine sealant.

For optimal performance, the transducer must be installed:

As close as possible to the centerline of the transom.At least 38 cm (15 inches) away from the propeller.On the starboard side (right when facing forward) if the propeller rotates clockwise, or on the port side (left) if it rotates counterclockwise, to avoid propeller wash.In a clean water zone (non-turbulent), away from seams, reinforcements, fittings, water discharge outlets, or anything that could create air bubbles.

The transducer must be mounted parallel to the boat's waterline. It should extend approximately 3.5 mm (0.125 in) below a fiberglass hull or 10 mm (0.375 in) below an aluminum hull to ensure direct and clear contact with the water.

To reduce interference, follow these recommendations:

Electromagnetic Interference (EMI): Route the transducer cable away from ignition wires, batteries, trolling motors, and high-energy cables (radar, audio, autopilot). If the cable must cross a power cable, do so at a 90-degree angle. A ferrite choke can be used.
Acoustic Interference: Mount the transducer as far as possible from equipment or hull features (planking, chines, ribs) that may agitate the water.
Acoustic Interference: Avoid mounting the transducer near propellers, shafts, cables, other machinery, or at the rear of through-hulls and water intake/discharge openings. If using multiple transducers, space them at least 60 cm (24 in) apart.

Yes, if your boat spends a lot of time in the water, it is recommended to apply a water-based antifouling paint on the transducer and mounting hardware. Before application, lightly sand the transducer with a fine abrasive pad and clean it with isopropyl alcohol. Never use acetone.

Yes, this transducer can be installed on an electric motor. Installation requires the use of hose clamps to secure the transducer bracket to the motor body. The cable must be routed to avoid any pinching or excessive bending when deploying or stowing the motor.

The transducer cable must be routed away from ignition wires, batteries, trolling motors, and high-energy wires (radar, audio amplifier, autopilot pump) to minimize noise and interference. Avoid sharply pinching or bending the cable. If running it through the transom, use a through-hull opening well above the waterline and seal it with marine sealant and the supplied cable gland.

When installing screws on a fiberglass hull, it is recommended to use a countersink drill bit to pre-drill only through the top gelcoat layer. This prevents cracks in the gelcoat when the screws are tightened. Always apply marine sealant to the screw threads to prevent water from seeping into the transom.

After installation, launch the boat and check for leaks around the screw holes below the waterline. Power on the chartplotter and navigate at low speed, then gradually increase. If the sonar signal is lost or degraded at a certain speed, note that speed and make moderate turns. If the signal improves when turning, adjust the transducer so it extends 3 mm (1/8 in) lower under the transom. Repeat until degradation is eliminated. If the signal does not improve, relocate the transducer to another position.

Yes, it is important to update the software of your Garmin chartplotter when installing this depth sounder to ensure optimal performance and compatibility. Update instructions are available in your chartplotter’s user manual at support.garmin.com.

Although this transducer has a spray shield, if you notice excessive water spray, it is advisable to review the mounting considerations and adjust the position of the transducer. Adjusting its depth or angle often resolves this issue. A sturdy transom mount with a spray shield (Garmin reference 010-12006-11) is also available as an option to reduce spray.

It is critical never to cut the transducer cables, as this would void the product warranty. Any unauthorized modification of the cables or the transducer itself may also invalidate the warranty.

No, the transducer must not be installed behind frames, reinforcements, fittings, water discharge openings, or any other hull feature that could create air bubbles or turbulent water. For optimal performance, the transducer must have direct and unobstructed contact with smooth water.
