Sondi GT15M-IH – sisemine CHIRP keskmise sagedusega

The Garmin GT15M-IH is an in-hull transducer made of plastic. It uses CHIRP technology in the mid-band for optimal performance.

The GT15M-IH transducer operates on a CHIRP frequency range in the mid-band, from 85 to 165 kHz. This band provides detailed depth readings.

The Garmin GT15M-IH transducer has a transmission power of 600 W (RMS), providing strong detection capability.

No, hull-mounted transducers like the GT15M-IH typically do not include temperature or speed sensors. They only provide traditional CHIRP depth data.

The main advantages of an in-hull transducer include:

No hull drilling required.Reduced drag as the transducer is installed inside the boat.Protection against external damage (trailers, underwater obstacles).Maintains accurate depth readings even at high speeds.

The Garmin GT15M-IH transducer is equipped with an 8-pin connector, compatible with suitable Garmin fishfinders and chartplotters.

The GT15M-IH sounder is designed exclusively for solid fiberglass hulls. It is compatible with hulls up to 16 mm (5/8 in) thick.

No, the GT15M-IH transducer is not recommended for metal, wood, or cored hulls. It is specifically designed for solid fiberglass hulls.

The Garmin GT15M-IH transducer is compatible with solid fiberglass hulls up to 16 mm (5/8 in) thick.

The GT15M-IH transducer is recommended for hulls with a deadrise angle between 0 and 25 degrees. Four plastic fairings are included to match these angles.

No, the GT15M-IH transducer only provides traditional CHIRP depth sounder data. To add ClearVü or SideVü functions, it can be supplemented with other compatible Garmin transducers (such as the GT36UHD-TM or GT56UHD-TM) via an optional Y-cable.

Yes, you can supplement the GT15M-IH transducer with other Garmin transducers, such as the GT36UHD-TM or GT56UHD-TM models, to add ClearVü and SideVü functionality. This requires the use of an optional Y-cable.

For optimal performance, the depth sounder must be installed:

On a solid fiberglass hull area, free of air pockets or core material.In the bilge area, near the keel and the transom.As flat as possible.Away from water intakes, protrusions, strakes, and turbulence generated by the propeller.

To install the GT15M-IH transducer, you will need:

A Phillips screwdriver size #1.

The tank choice depends on the deadrise angle of your hull:

For an angle of 0 to 3 degrees, install the tank labeled 0°. For an angle of 4 to 8 degrees, install the tank labeled 5°. For an angle of 9 to 16 degrees, install the tank labeled 12°. For an angle of 17 to 25 degrees, install the tank labeled 20°.

Yes, it is strongly recommended to test the mounting location before permanent installation. You can place the transducer in a plastic bag filled with water, position it on the wetted hull at the chosen location, and check the readings on your chartplotter or depth sounder to verify performance.

The GT15M-IH transducer's tank must be filled with RV/marine antifreeze fluid or mineral oil. This fluid ensures proper transmission of the sonar signal through the hull.

You can measure the deadrise angle using a smartphone app, an angle finder, a protractor, or a digital level. It is important to measure this angle specifically at the location where you plan to install the transducer, as the hull may have multiple different angles.

Although hull-mounted installation is less invasive than through-hull transducers, professional installation is recommended for optimal performance. This ensures correct placement and maximum transducer efficiency.
