Sonda GT51M-TM - tauler posterior CHIRP/ClearVü/SideVü

For optimal performance, the GT51M-TM transducer must be installed in a clean water area (non-turbulent) and in direct, unobstructed contact with the water. Here are some important considerations:

Mount the transducer as close as possible to the center of the boat.Avoid mounting it behind frames, struts, fittings, water intake or discharge openings, or anything that could create air bubbles or cause turbulence.On single-engine boats, do not mount the transducer in the propeller wash to avoid cavitation and damage.On twin-engine boats, mount the transducer between the two engines if possible.Avoid areas where the transducer could be struck during launching, towing, or storage.

No, cutting the transducer cables is strongly discouraged. Doing so voids your warranty. It is important to plan the cable routing carefully to avoid excess length or interference.

The GT51M-TM transom-mount transducer is compatible with all hull materials. Unlike other transducer types (such as through-hull or in-hull models), transom mounting does not depend on hull material for signal transmission.

After installation, test your transducer in open water free of obstacles:

Put the boat in the water and turn on your chartplotter. Drive the boat at low speed. If the chartplotter is working correctly, gradually increase speed while monitoring the screen.

If the sonar signal is suddenly lost or if the bottom return is severely degraded, note the speed at which this occurs. Return to the speed where the signal was lost and make moderate turns in both directions while observing the chartplotter.

If the signal strength improves while turning, adjust the transducer so that it extends 3 mm (1/8 in) further below the boat’s transom. Repeat steps 2 to 4 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 ensure there are no leaks around the screw holes added below the waterline before leaving the boat in the water for an extended period.

Garmin GT-series transducers, including the GT51M-TM model, are designed to provide advanced sonar capabilities. They typically include ClearVü™ and SideVü™ technologies.

ClearVü: This technology delivers near-photographic imaging of what lies beneath your vessel, allowing you to clearly distinguish structures, submerged objects, and fish.SideVü: This function scans the sides of your boat to provide a detailed view of what is on either side, useful for locating structures and fish over wide areas.These technologies complement traditional sonar for a better understanding of the underwater environment.

The Garmin GT51M-TM transducer integrates three sonar technologies:

Traditional CHIRP sonar for excellent target separation.ClearVü CHIRP sonar for near-photographic images of what lies beneath your boat.SideVü CHIRP sonar for detailed images of what lies alongside your boat.

Yes, the Garmin GT51M-TM transducer is equipped with an integrated temperature sensor that measures water temperature.

The Garmin GT51M-TM transducer is a transom-mount transducer. It attaches to the outside of the boat's transom using a bracket and screws.

The Garmin GT51M-TM transducer is compatible with all hull materials. It is designed to be mounted on the transom, making it versatile for different types of boats.

To install the GT51M-TM transducer, you will need the following tools:

Drill and drill bits.Two 13 mm hex wrenches.Phillips screwdriver #2.Masking tape.Marine sealant.

For optimal performance, the depth sounder must be mounted as close as possible to the centerline of the boat, in an area of clean (non-turbulent) water. Avoid placing it behind strakes, frames, fittings, scuppers, or any other obstruction that could create air bubbles. It must also not be in the path of the propeller on single-engine boats.

No, the cables connected to the depth sounder must not be cut. Cutting the depth sounder cables voids the product warranty.

The drill diameter depends on the cable type:

For a 4-pin cable, use a 16 mm (5/8 in) drill bit. For an 8- or 12-pin cable, use a 25 mm (1 in) drill bit. Ensure you drill above the waterline if passing the cable through the transom.

To reduce interference, mount the transducer away from potential sources such as propellers, shafts, electrical cables, engines, radar, and hull features that create turbulence (strakes, chines). Avoid mounting it behind through-hull fittings, sea cocks, or water discharge outlets. If multiple transducers are used, space them at least 60 cm (24 in) apart and avoid operating two transducers of the same frequency simultaneously.

The warranty of your Garmin GT51M-TM depth sounder could be voided if the probe cables are cut. It is imperative not to modify the cables to maintain warranty validity.

The GT51M-TM transducer is designed to work with Garmin chartplotters and fishfinders compatible with traditional CHIRP, ClearVü, and SideVü technologies. It is recommended to verify the specific compatibility of your Garmin chartplotter model with the GT51M-TM transducer before purchase or installation.
