Sonda HD-ID / ClearVü průchozí plastová 4kolíková

This Garmin transducer integrates two main sonar technologies:

Traditional HD-ID sonar: Operating at 77/200 kHz frequencies, it effectively displays fish arches and tracks the seabed with precision.
ClearVü™ sonar: Operating at 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 m (1,900 ft) with traditional HD-ID sonar (77/200 kHz).Up to 228 m (750 ft) with ClearVü™ sonar (455/800 kHz).

Yes, this Garmin transducer has a built-in temperature sensor that measures 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 vessels.

This transom-mounted transducer is compatible with hulls of all materials. It is particularly suited to towed boats. However, it is not recommended for sailboats due to excessive heel, nor for stepped-hull boats.

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 mounted:

As close as possible to the centerline of the transom.At least 38 cm (15 inches) 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 outlets, or any other features 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 90 degrees. A ferrite choke can be used.

Turbulence-induced interference: Mount the transducer as far as possible from hull fittings or features (seams, chines, strakes) that may agitate the water.

Acoustic interference: Avoid mounting the transducer near propellers, shafts, cables, other machinery, or behind 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 fine abrasive foam 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 mount to the motor body. The cable must be routed to avoid any pinching or excessive bending during motor deployment or stowage.

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 routing through the transom, use a through-hull hole 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. Turn on the chartplotter and navigate at low speed, then gradually increase speed. If the sonar signal is lost or degraded at a certain speed, note that speed and perform moderate turns. If the signal improves while turning, adjust the transducer so it extends 3 mm (1/8 in) lower below the transom. Repeat until the degradation is eliminated. If the signal does not improve, move the transducer to another location.

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 includes a spray shield, if you observe excessive water spray, it is advisable to review the mounting considerations and adjust the probe's position. Adjusting its depth or angle often resolves this issue. A robust transom mount with a spray shield (Garmin part number 010-12006-11) is also available as an option to reduce spray.

It is critical never to cut the transducer cables, as this will 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 outlets, or any other hull feature that could create air bubbles or cause turbulent water flow. For optimal performance, the transducer must have direct and unobstructed contact with smooth water.
