GT17M-THF 12° átmenő szonda - közepes frekvenciájú CHIRP

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

Yes, Garmin strongly recommends that 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 prevent 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, quick-drying, 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 size of the hole 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 an aluminum or steel hull: 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 absolutely requires the use of the included galvanic isolation components. Failure to install these components would result in galvanic corrosion, which could cause water ingress around the transducer and damage the hull.

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 running it in air can cause heat damage.
