GT15M-THF 0° átmenő szonda – közepes frekvenciájú CHIRP

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

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

The "0 degree" designation 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’s 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 technician is highly recommended. It is also important to always wear safety glasses, hearing protection, and a dust mask when drilling, cutting, or sanding.

The required hole diameters vary depending 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 supplied with the transducer. Failing to install these components would cause galvanic corrosion, potentially leading to water ingress around the transducer and damaging your boat.

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

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

Yes, you must update the software on your Garmin chartplotter when installing 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 high-pressure cleaner to clean the transducer.A mild detergent or rubbing alcohol can be used for cleaning.

The Garmin GT15M-THF transducer is made of stainless steel. This material ensures robustness and 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 critical to check your boat's deadrise angle at the chosen installation location to ensure optimal sonar performance.

Drill 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, the use of the included galvanic isolation components is mandatory when installing the GT15M-THF transducer on an aluminum or steel hull. Failing 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 of clean, non-turbulent water. 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.Long-keeled boats: At a slight angle pointing toward the bow, parallel to the centerline.Fin-keel boats: 25 to 75 cm in front of the keel and a maximum of 10 cm to the side of the centerline.Displacement-hull boats: Approximately one-third back from the waterline length from the bow, and 150 to 300 mm to the side of the centerline.The transducer must not be mounted behind ribs, stiffeners, fittings, water inlets or outlets, or anything that could create air bubbles or cause turbulent water.

The transducer must always be used when submerged. Operating it in the air can cause damage due to overheating. 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 high-pressure cleaner to clean the transducer. Avoid pulling or lifting the transducer by its cable to prevent damage.

To achieve the best possible performance and avoid potential damage to the device or your sailboat, 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) drill bitAn adjustable wrench suitable for nuts up to 75 mmMarine sealant (flexible, quick-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 hullsGrommets and water-based antifouling paint 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 depth sounder cable, unless necessary for connection 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 transducer from inside the hull until the arrow on the top of the transducer points toward the keel of the boat. This alignment is essential for the internal angle of the transducer to match the keel angle of the boat, ensuring optimal performance.
