Sonda GT56UHD-THP - pár průchozích sond UHD ClearVü/SideVü

The Garmin GT56UHD-THP is a thru-hull transducer designed for a robust and permanent installation through your vessel's hull. This type of installation ensures stable and reliable sonar data acquisition, even at high speeds, as the transducer is securely integrated and less exposed to turbulence than transom-mounted models.

For optimal performance, the GT56UHD-THP transducer must be mounted in an area of clear water, free from turbulence generated by strakes, frames, fittings, or water intakes/outlets. It is essential to position it parallel to the fore-aft axis of the vessel. Specific locations vary depending on hull type:

Outboard and inboard vessels: In front of and near the engine (outboard/sterndrive) or in front of and away from the propeller/shaft (inboard).Step hulls: In front of the first step.Full keel hulls: With a slight angle pointing forward, parallel to the centerline.Fin keel hulls: 25 to 75 cm in front of the keel and no more than 10 cm from the centerline.Displacement hulls: Approximately one-third of the waterline length from the bow, and 150 to 300 mm to the side of the centerline.

Yes, it is mandatory to update the software of your Garmin chartplotter when installing the GT56UHD-THP transducer. This update is essential to ensure full compatibility and proper operation of the device with your system. You can find the update instructions in your plotter's user manual or on support.garmin.com.

Using a fairing block is recommended if the deadrise angle of the hull at the mounting location exceeds 5°. The fairing block allows positioning the transducer parallel to the waterline, which optimizes sonar accuracy. You will need to measure the deadrise angle of your hull to determine whether a fairing block is necessary in your case.

Yes, the GT56UHD-THP transducer is designed to be installed on various hull types, including fiberglass hulls (with or without core) and metal hulls. The installation instructions provide specific steps and suitable tools for each hull type to ensure secure and watertight mounting. It is critical to follow these detailed instructions to avoid damaging the vessel and ensure the transducer's performance.

When installing the Garmin GT56UHD-THP transducer, several safety precautions are essential:

Wear protective equipment: Always wear safety goggles, hearing protection, and a dust mask when drilling, cutting, or sanding. Check the surface: Before drilling or cutting, always check what is on the other side of the surface to avoid damaging the vessel. Anti-rotation bolts: The device must be installed with one or more anti-rotation bolts (included). Failure to do so may cause the unit to rotate while underway and damage your vessel. Qualified installer: This equipment should be installed by a qualified marine technician. Cable positioning: To prevent damage to the cable and transducer, do not use the cable to lift or pull the transducer.

The Garmin GT56UHD-THP transducer is designed to deliver Ultra High Definition (UHD) sonar capabilities. It supports:

ClearVü UHD scanning sonar for near-photographic images of fish and underwater structures.SideVü UHD scanning sonar for a detailed view of what is on each side of your boat.The traditional CHIRP high and wideband frequency sonar for clear fish target detection and excellent target separation.These combined technologies ensure stable and reliable data acquisition for better knowledge of the underwater environment.
