Sonda GT17M-THF 12° - prečna CHIRP srednje frekvence

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 purchased transducer's angle 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 optimal performance of the device but also helps prevent potential damage to the transducer or the vessel.

To install 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 its 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 result in galvanic corrosion, which could cause water ingress around the transducer and damage the hull.

To maintain and clean your Garmin GT17M-THF transducer, follow these guidelines:

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 high-pressure washer to clean the transducer.Always ensure the transducer is submerged when operating, as operation in air can cause heat damage.

Use only mild soap and water for cleaning. Rinse thoroughly and dry with a soft cloth.

Inspect the transducer regularly for signs of wear, cracks, or marine growth. Remove any fouling with a soft brush or sponge.

Avoid dropping or striking the transducer, as impacts can affect its performance.

Refer to the Garmin GT17M-THF user manual for detailed maintenance procedures and specifications.

If in doubt, contact Garmin technical support or a certified marine electronics technician.
