Sonda GT54UHD-TM - tauler posterior 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 in this transducer uses a frequency of 800 kHz, with a range from 760 to 880 kHz.

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

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

The GT54UHD-TM traditional CHIRP depth sounder 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 mounted on the transom like 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-bottom hulls. For vee-bottom hulls, it should be installed 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 transom, you will need:

A Phillips screwdriver #2
A drill
Drill bits: 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 voids your warranty.

Yes, if your boat spends a lot of time in the water, it is recommended to apply water-based antifouling paint on the depth sounder and mounting hardware to prevent marine growth. Do not use acetone or acetone-based products, as they will damage the probe'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 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 on the transom and repeat the test.Also check for leaks around the screw holes below the waterline.

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

Yes, the GT54UHD-TM transducer is designed to be installed on an electric motor. Use the supplied hose clamps to secure it to the motor body and route the cable to prevent 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.
