Sonda GT51M-THP - průchozí dvojice CHIRP/ClearVü/SideVü

The Garmin GT51M-THP transducer uses CHIRP medium sonar, ClearVü and SideVü technologies. These technologies enable detailed detection of fish and underwater structures.

The GT51M-THP transducer is designed for installation on fiberglass hulls (with or without core) and metal hulls. Its through-hull design is optimized for these materials, providing installation flexibility for a wide range of vessels.

The GT51M-THP through-hull transducer is recommended for superior performance as it eliminates interference and turbulence often encountered with transom-mount transducers. Its installation through the hull ensures a clean water flow over the transducer element, maximizing the efficiency of ClearVü, SideVü, and CHIRP technologies.

Yes, using a fairing block is recommended if the hull drift angle exceeds 5°. This allows positioning the transducer parallel to the waterline, ensuring improved sonar accuracy and minimizing cavitation.

For installing the Garmin GT51M-THP transducer, you will need the following tools:

A drillBits of 3 mm (1/8 in), 9 mm (3/8 in), and 13 mm (1/2 in)A 13 mm (1/2 in) open-end or adjustable wrenchA wrench suitable for nuts up to 38 mm (1 1/2 in)Marine sealant (flexible, fast-curing, for below the waterline)Mild household detergent or rubbing alcoholSandpaperMasking tapeWaterproof electrical tapeHole saws of 25 mm (1 in) or 32 mm (1 1/4 in) may be required depending on hull type, along with a jigsaw or bandsaw and a rasp if a fairing block is used.

After printing the mounting template, it is crucial to use a ruler to measure at least one dimension line to verify that the template was printed at 100% scale. It is recommended to use the template provided in the product box. If you print your own, ensure the scale option is set to 100% in the PDF print settings of your application.

On outboard and sterndrive motorboats, the GT51M-THP transducer must be mounted forward and close to the engine(s). It is essential to choose a location where the water is clean and non-turbulent, away from keels, struts, fittings, water intakes or discharge outlets that could create air bubbles. The transducer must be in non-turbulent water for optimal performance.
