Sonda GT15M-THF 0° - transversal CHIRP freqüència mitjana

Yes, the Garmin GT15M-THF transducer is made of stainless steel and is compatible with a wide range of hull materials, including fiberglass, wood, composites, aluminum, and steel.

For installations on metal hulls (aluminum or steel), it is essential to use the included galvanic isolation components to prevent corrosion and ensure watertightness.

The designation "0 degrees" for this transducer indicates it is specifically designed and optimized for deadrise angles ranging from 0 to 5 degrees. For optimal sonar performance, it is critical that the transducer angle matches as closely as possible the deadrise angle at the chosen installation location on your boat.

Yes, to achieve the best possible performance and avoid potential damage to the device or your boat, installation by a qualified marine installer is strongly recommended. It is also important to always wear safety glasses, hearing protection, and a dust mask when drilling, cutting, or sanding.

The required drill diameters depend on your boat's hull material:

For a fiberglass hull (solid or cored), a 73 mm (2 7/8 in) hole saw is required.For a metal hull (aluminum or steel), a 75 mm (3 in) hole saw is required.

For installations on aluminum or steel hulls, it is mandatory to use the galvanic isolation components included with the transducer. Omitting these components during installation would create galvanic corrosion that could lead to water ingress around the transducer and damage your boat.

Yes, for optimal performance, the transducer must be installed in an area of clean, non-turbulent water. Here are the key points:

Avoid installing it behind ribs, struts, fittings, water intake or discharge openings, or anything that could create air bubbles.It must not be installed in the propeller wash path, as this could cause cavitation.On outboard or sterndrive-powered boats, it is typically mounted at the bow and near the engine(s).On inboard-powered boats, it must be mounted at the bow and away from the propeller and the engine shaft.The arrow on the top of the transducer must be aligned with the boat’s keel so that the internal angle aligns with the keel angle.

Yes, it is necessary to update the software on your Garmin chartplotter when you install this transducer. This update ensures compatibility and optimal operation between the transducer and your Garmin device.

To avoid permanently damaging the transducer surface, follow these recommendations:

Never use solvents such as white spirit, acetone, methyl ethyl ketone (MEK), or similar products.Do not use an electric sander or pressure washer to clean the transducer.A mild detergent or isopropyl alcohol can be used for cleaning.

The Garmin GT15M-THF transducer is made of stainless steel. This material ensures robustness and broad compatibility with various hull types, including fiberglass, wood, composites, aluminum, and steel.

The GT15M-THF transducer is compatible with fiberglass, wood, composite, aluminum, and steel hulls. Its stainless steel construction makes it particularly suitable for metal hulls, unlike other brass models.

The Garmin GT15M-THF transducer is specifically designed for deadrise angles ranging from 0 to 5 degrees. It is crucial to verify your boat's deadrise angle at the chosen installation location to ensure optimal sonar performance.

Hole diameters vary depending on your hull material:

For fiberglass hulls (solid or sandwich): a 73 mm (2 7/8 in) hole is required.For metal hulls (aluminum or steel): a 75 mm (3 in) hole is required.

Yes, using the included galvanic isolation components is mandatory when installing the GT15M-THF transducer on an aluminum or steel hull. Failure to install them could lead to galvanic corrosion and potential water ingress around the transducer.

For optimal performance, the transducer must be installed in an area with clean, non-turbulent water flow. Here are some general guidelines:

Outboard and sterndrive boats: In front of and near the engine(s).Inboard boats: In front of and away from the propeller and propeller shaft.Longitudinal-stepped hulls: In front of the first step.Deep-keel boats: At a slight angle pointing forward, parallel to the centerline.Fine-keel boats: Between 25 and 75 cm in front of the keel and no more than 10 cm to the side of 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.The transducer must not be mounted behind frames, stringers, fittings, water intakes or discharges, or anything that could create air bubbles or cause turbulent water flow.

The transducer must always be used when submerged. Operating it in air can cause damage due to overheating.
For cleaning, never use solvents such as white spirit, acetone, MEK (methyl ethyl ketone), or similar products, as they can permanently damage the transducer's surface.
Do not use an electric sander or pressure washer to clean the transducer.
Do not pull or lift the transducer by its cable to avoid damaging it.

To achieve optimal performance and avoid potential damage to the device or your boat, installation by a qualified marine technician is recommended.

For installing the transducer, you will need the following tools:

A drill and a 3 mm (1/8 in) bitA wrench suitable for nuts up to 75 mmMarine sealant (flexible, fast-curing type for below the waterline)Mild household detergent or rubbing alcoholSandpaperMasking tapeWaterproof electrical tapeA 73 mm (2 7/8 in) hole saw for fiberglass hulls or a 75 mm (3 in) hole saw for metal hulls.Water-based antifouling paint and grommets may be required as optional items.

Yes, the GT15M-THF transducer is made of stainless steel and is specifically designed for installation in aluminum or steel hulls, as well as fiberglass, wood, or composite hulls. It includes galvanic isolation components to prevent corrosion in metallic environments.

Yes, cutting or splicing the transducer cable, unless required to connect to a specific black box sonar unit, may void your warranty. It is recommended not to modify the cable.

During installation, it is crucial to rotate the depth sounder from inside the hull until the arrow on top of the transducer points toward the keel of the boat. This alignment is essential so that the internal angle of the transducer matches the keel angle of the boat, ensuring optimal performance.
