Sondă GT8HW-TM din plastic, pentru montare pe pupă sau motor electric, CHIRP larg și înalt (150-240 kHz, 250 W) (8 pini)

The Garmin GT8HW-TM transducer is designed for shallow-water fishing. Its primary function is to provide accurate detection in freshwater, offering clear bottom definition, sharp fish arches, and effective target separation thanks to its wide and high CHIRP sonar technology.

The Garmin GT8HW-TM transducer is optimized for freshwater fishing.

The GT8HW-TM transducer provides accurate detection in freshwater up to 800 feet, which is approximately 244 meters.

The GT8HW-TM transducer integrates CHIRP wide and high sonar technology (High-Wide CHIRP).

The GT8HW-TM transducer operates over a CHIRP frequency range of 150 to 240 kHz.

The GT8HW-TM transducer has a transmission power of 250 W.

The GT8HW-TM transducer offers a beam angle of up to 24 degrees, providing extended coverage and reliable fish detection.

No, the GT8HW-TM transducer is exclusively focused on traditional High-Wide CHIRP sonar. It does not include ClearVü or SideVü technologies, which are available on other, more advanced Garmin models.

The Garmin GT8HW-TM transducer is made of plastic.

The GT8HW-TM transducer is compatible with a range of Garmin devices, including:

STRIKER chartplotters/depth sounders
echoMAP CHIRP devices
GPSMAP devices
GSD25 sounder module

The GT8HW-TM transducer is equipped with an 8-pin connector.

The Garmin GT8HW-TM transducer is designed for installation on the transom or on an electric motor.

For optimal performance, the transducer must be mounted as close as possible to the center of the boat, in an area of clean water (non-turbulent). It is crucial to avoid placing it behind frames, reinforcements, fittings, through-hulls, or any other openings that could create air bubbles or cause turbulent water. For single-engine boats, avoid the propeller wash path.

To minimize interference with the sonar signal:

Route the transducer cable away from ignition wires, batteries and service wires, trolling motor batteries and wires, and high-energy wires (radar, audio amplifier, autopilot pump). Avoid mounting the transducer near sources of electromagnetic or acoustic interference, such as other transducers (space them at least 60 cm apart if they share the same frequency), propellers, shafts, or other machinery. If the cable must cross a power cable, orient the cables at 90 degrees.

No, it is strongly recommended not to cut the transducer cable. Cutting the transducer cables voids the product warranty.

When mounting on the transom, the bottom center of the transducer must be level with the lower edge of the transom and parallel to the waterline. The transducer must be in direct contact with smooth, unobstructed water for optimal performance. The waterline may vary depending on the boat's load and speed.

Yes, if your boat spends a significant period in the water, it is recommended to coat the transducer and mounting hardware with water-based antifouling paint to prevent marine growth. Before application, lightly sand the transducer and hardware with a fine abrasive pad, then wipe them with isopropyl alcohol. Never use acetone.

To mount the transducer on an electric motor:

Insert the hose clamp into the slot of the transducer bracket so that equal lengths protrude on both sides. Position the transducer bracket against the electric motor body with the narrow end of the transducer pointing away from the propeller. Secure the hose clamp around the motor body and tighten it. Align the transducer so that it is parallel to the hull bottom when in use. Use the provided cable ties to secure the transducer cable, ensuring it is not pinched during motor deployment or stowage.

When assembling the depth sounder, the mounting bolt must be tightened enough to keep the transducer in place at high speed, but loose enough to allow the transducer to pivot and deflect if it hits an obstacle. This helps prevent damage to the transducer.

The propeller creates a current (the "prop wash") that can interfere with the sonar signal. To avoid this:

Observe the propeller’s rotation direction. If it turns clockwise, it generates turbulence on the port side (left side of the boat facing forward); mount the transducer on the starboard side (right side). If it turns counterclockwise, it generates turbulence on the starboard side; mount the transducer on the port side. For transom mounting, it is recommended to place the transducer at least 38 cm (15 inches) from the propeller and on the side opposite to the "prop wash".
