Sondi GT54UHD-TM – tagumine paneel UHD ClearVü/SideVü

The Garmin GT54UHD-TM transducer is an all-in-one Ultra High Definition (UHD) transducer that integrates traditional CHIRP sonar, ClearVü, and SideVü technologies.

The UHD ClearVü CHIRP sonar of this transducer uses a frequency of 800 kHz, with a range from 760 to 880 kHz.

The UHD SideVü CHIRP sonar of this transducer uses a frequency of 1200 kHz, with a range from 1020 to 1230 kHz.

The UHD SideVü provides a side range of 125 feet (250 feet total) with a maximum depth of 30 feet (approximately 9 meters).

The GT54UHD-TM traditional CHIRP fishfinder has a power output of 350W and a frequency range of 150-240 kHz, reaching a maximum depth of 800 feet (approximately 244 meters).

The Garmin GT54UHD-TM transducer is designed for transom mount or trolling motor mount installation.

Transducers with transom-mount installation, such as the GT54UHD-TM, work with any hull material.

No, the GT54UHD-TM transducer is not recommended for sailboats due to excessive heel, nor for vee-hull vessels. For vee-hull hulls, it should be mounted at the lowest point before the first chine.

If your propeller rotates clockwise, creating turbulence on the port (left) side, the depth sounder must be mounted on the starboard (right) side. If your propeller rotates counterclockwise, creating turbulence on the starboard (right) side, the depth sounder must be mounted on the port (left) side.

For installation on the stern, you will need:

A Phillips screwdriver size #2
A drill
Drill bits of 4 mm (5/32 in), 3.2 mm (1/8 in), and 25 mm (1 in)
Masking tape
Marine sealant

No, it is imperative not to cut the transducer cables. Cutting the transducer cables will void your warranty.

Yes, if your boat spends a lot of time in the water, it is recommended to apply water-based antifouling paint to the transducer and mounting hardware to prevent marine growth. It is important not to use acetone or acetone-based products, as this would damage the transducer's plastic housing.

If you have a 4-pin cable, use a 16 mm (5/8 in) drill bit. If you have an 8- or 12-pin cable, use a 25 mm (1 in) drill bit. Make sure to choose a location well above the waterline and apply marine sealant.

Test the installation in open water:

Put the boat in the water and power on the chartplotter. Drive the boat at low speed. If the sonar works correctly, gradually increase speed while monitoring the chartplotter. If the signal is lost or degraded, note the speed. Return to this speed and perform moderate turns in both directions. If the signal improves when 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 on the transom and repeat the test. Also check for leaks around the screw holes below the waterline.

Yes, you must update the software on your Garmin chartplotter when installing this device to ensure compatibility and optimal performance. Update instructions are located in your chartplotter's user manual.

Yes, the GT54UHD-TM transducer is designed to be installed on an electric motor. You must use the supplied hose clamps to secure it to the motor body and route the cable to avoid pinching when deploying or stowing the motor.

Yes, you can use multiple transducers, but it is recommended to mount them at least 60 cm (24 inches) apart to avoid interference. If the transducers have the same frequency, they will interfere if used simultaneously. Transducers with different frequencies can be used at the same time without issues.
