Sonda GT51M-TM - zadní panel CHIRP/ClearVü/SideVü

For optimal performance, the GT51M-TM transducer must be installed in an area of clean water (non-turbulent) and in direct, unobstructed contact with the water. Key considerations include:

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 prevent 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, it is strongly discouraged to cut the fishfinder/sound transducer cables. Cutting the fishfinder/sound transducer cables voids your warranty. It is important to carefully plan the cable routing to avoid it being too long or causing 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 depth sounder in open water free of obstacles:

Launch the boat and power on your chartplotter. Drive the boat at low speed. If the chartplotter operates correctly, gradually increase speed while monitoring the screen. If the sonar signal is suddenly lost or 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 signal strength improves while turning, adjust the transducer so it extends 3 mm (1/8 in) further below the boat’s transom. Repeat steps 2 to 4 until 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 fishfinders, such as the GT51M-TM model, are designed to provide advanced sonar capabilities. They typically include ClearVü™ and SideVü™ technologies.

ClearVü: This technology provides a near-photographic image of what lies beneath your boat, allowing you to clearly distinguish structures, submerged objects, and fish. SideVü: This function scans the sides of your boat to give you a detailed view of what is on each 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 has a built-in temperature sensor for measuring water temperature.

The Garmin GT51M-TM transducer is a transom-mounted 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.

For the installation of the GT51M-TM transducer, you will need the following tools:

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

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). Avoid placing it behind frames, struts, fittings, drains, or any other elements 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 transducer must not be cut. Cutting the transducer cables voids the product warranty.

The drill diameter depends on the cable type:

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. Ensure you drill above the waterline if running the cable through the transom.

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

The warranty of your Garmin GT51M-TM transducer could be voided if the transducer 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.
