Sonda GT15M-IH - vnitřní CHIRP střední frekvence

The Garmin GT15M-IH is an in-hull type 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 transmit power of 600 W (RMS), giving it good detection capability.

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

The main advantages of an in-hull transducer include:

No hull drilling required.Reduction in drag since the transducer is installed inside the hull.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 transducer 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 tanks are supplied to accommodate these different angles.

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

Yes, you can add additional Garmin transducers to the GT15M-IH, such as the GT36UHD-TM or GT56UHD-TM models, to enable ClearVü and SideVü functions. This requires the use of an optional Y-cable.

For optimal performance, the transducer must be mounted:

On a solid fiberglass hull area, without air pockets or core material.In the bilge area, near the keel and transom.As flat as possible.Away from water intakes, protrusions, seams, and turbulence generated by the propeller.

For installing the GT15M-IH transducer, you will need:

A Phillips screwdriver size #1.
220-grit sandpaper.
High-quality marine-grade adhesive suitable for the hull material.
RV/marine antifreeze or mineral oil.
Isopropyl alcohol.

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

For a deadrise angle of 0 to 3 degrees, install the tank labeled 0°. For a deadrise angle of 4 to 8 degrees, install the tank labeled 5°. For a deadrise angle of 9 to 16 degrees, install the tank labeled 12°. For a deadrise 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 hull wetted at the chosen location, and observe the feedback on your chartplotter or depth sounder to verify performance.

The GT15M-IH transducer’s housing must be filled with RV/marine antifreeze or mineral oil. This liquid 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 results. This ensures proper placement and maximum performance of the transducer.
