Sonda GT17M-THF 12° - transversal CHIRP freqüència mitjana

The Garmin GT17M-THF fishfinder is designed to be installed on a wide range of hull materials. Its stainless steel housing makes it compatible with fiberglass, wood, composite, aluminum, or steel hulls.

It is important to note that when installing on aluminum or steel hulls, the included galvanic isolation components must be installed to prevent corrosion.

The Garmin GT17M-THF transducer with an internal angle of 12 degrees is specifically designed to compensate for hull deadrise angles ranging from 6 to 16 degrees. For optimal performance, the angle of the purchased transducer should be as close as possible to the deadrise angle measured at the installation location.

Yes, Garmin strongly recommends that the installation of the GT17M-THF transducer be performed by a qualified marine installer. This ensures not only the best possible performance of the device but also helps avoid potential damage to the transducer or the vessel.

For installing the Garmin GT17M-THF transducer, you will need the following tools:

A drill with a 3 mm (1/8 in) bitA wrench suitable for nuts up to 108 mm (4 1/4 in)A 4.5 mm (3/16 in) Allen keyMarine sealant (flexible, fast-curing, for below the waterline)Sandpaper and masking tapeFor fiberglass hulls: a 98 mm (3 7/8 in) hole sawFor metal hulls: a 101 mm (4 in) hole saw and a file

The hole size to drill in the hull depends on the hull material:

For a solid or laminated fiberglass hull: a 98 mm (3 7/8 in) hole saw is required.For a metal hull (aluminum or steel): a 101 mm (4 in) hole saw is required.It is crucial to verify your hull material before drilling.

Yes, installing the GT17M-THF transducer in an aluminum or steel hull requires the mandatory use of the included galvanic isolation components. Failure to install these components will cause galvanic corrosion, potentially leading to water ingress around the transducer and hull damage.

For maintenance and cleaning of your Garmin GT17M-THF transducer, follow these recommendations:

Never use solvents such as mineral spirits, acetone, methyl ethyl ketone (MEK) or similar products, as they can permanently damage the transducer surface.Do not use an electric sander or pressure washer to clean the transducer.Always ensure the transducer is submerged when in operation, as operation in air can cause heat damage.
