GT30-TH szonda – átmenő rozsdamentes ClearVü/SideVü

The GT30-TH transducer is compatible with Garmin chartplotters equipped with a 12-pin connection. For seamless integration and operation, a software update of the chartplotter is required.

The Garmin GT30-TH transducer is a through-hull stainless steel transducer that integrates ClearVü™ and SideVü™ sonar imaging technologies. It operates at frequencies of 455/800 kHz with 500W power and includes a temperature sensor. It is designed to be permanently mounted through the hull of your boat.

The GT30-TH transducer is specifically designed for hulls with tilts (drift angle) of less than 5°, ensuring optimal performance without requiring a compensating block. For hulls with a tilt greater than 5°, using a compensating block is recommended. This maintains the sonar beam perpendicular to the waterline and ensures optimal signal quality.

For optimal performance, the GT30-TH transducer must be installed in an area of clean, non-turbulent water. Here are some general considerations:

On outboard and sterndrive boats: Install the transducer in front of and near the engine(s).
On inboard boats: Install the transducer in front of and away from the propeller and propeller shaft.
On stepped hulls: Install the transducer in front of the first step.
On long-keel hulls: Install the transducer at a slight angle pointing forward, parallel to the centerline.
On fin-keel hulls: Install the transducer 25 to 75 cm (10 to 30 in) in front of the keel and no more than 10 cm (4 in) to the side of the centerline.
On displacement hulls: Install the transducer about one-third of the waterline length from the bow, and 150 to 300 mm (6 to 12 in) to the side of the centerline.
Avoid installing the transducer behind strakes, frames, fittings, through-hulls, or any other features that could create air bubbles or cause turbulent water.

To reduce interference with the sonar signal of your GT30-TH transducer, take the following measures:

Electromagnetic Interference (EMI): Ensure proper grounding of devices. If the transducer cable must cross a power cable, route the cables at 90 degrees to each other. You can also install a ferrite bead on the transducer cable and keep it away from other powered cables.\nInterference from turbulence: Mount the transducer as far as possible from any equipment or hull features (planking, chines, propeller) that could agitate the water. Areas of eroded paint on the hull often indicate turbulence zones to avoid.\nAcoustic interference: Mount the transducer away from propellers, shafts, cables, other machinery, and other transducers. If using multiple transducers, space them at least 60 cm (24 in) apart.

Yes, the Garmin GT30-TH transducer has an integrated sensor that measures and displays water temperature on your compatible chartplotter.

Yes, the GT30-TH transducer can be installed on a metal hull. Specific instructions are provided for preparing a metal hull, requiring the use of a file, a 13 mm (1/2 in) drill bit, and a 32 mm (1 1/4 in) hole saw for the shaft hole to ensure correct and secure installation.
