Pakki af mælitækjum Garmin GT36-TM og GT15M-IH

This package includes two separate transducers for versatile sonar coverage. It contains the GT36-TM transducer, designed for transom mounting on your boat, and the GT15M-IH transducer, intended for internal hull mounting.

The GT15M-IH transducer delivers a transmit power of 600 W (RMS). It can reach a maximum depth of 549 m (1,800 ft), depending on water conditions. Its operating frequencies range from 85 to 165 kHz; the exact range depends on your chartplotter or fishfinder model. Operating temperature range is 0°C to 50°C.

The GT36-TM transom-mounted transducer is compatible with all hull materials.The GT15M-IH in-hull transducer is specifically recommended for solid fiberglass hulls with a maximum thickness of 16 mm (5/8 in). It is not recommended for metal, wood, or sandwich (cored) hulls.

For optimal performance, the GT36-TM transducer must be mounted on the stern, parallel to the waterline. It is recommended to install it at least 38 cm (15 in) from the propeller and preferably on the starboard side if the propeller rotates clockwise (port side if the propeller rotates counterclockwise). The transducer must protrude approximately 3.5 mm (0.125 in) below a fiberglass hull or 10 mm (0.375 in) below an aluminum hull. Avoid turbulence zones created by strakes, keels, or other equipment.

The GT15M-IH transducer must be installed in the bilge, near the keel and the transom, on a solid fiberglass hull surface without air gaps or core material. It must be mounted as flat as possible. The hull's deadrise angle at the chosen location is critical for selecting the appropriate internal mounting tank (available for angles of 0-3°, 4-8°, 9-16°, and 17-25°). Avoid areas behind water intakes, protrusions, or sheer lines that could create turbulence.

No, it is strongly discouraged to cut the depth sounder cable. Cutting the depth sounder cable voids your warranty. If the cable is too long, it is recommended to coil it carefully or use a specific Garmin cable extension (part numbers 010-11617-42 or 010-11617-32) for the GT36-TM transducer, without exceeding 9 meters (30 feet) to avoid signal degradation.

Yes, it is mandatory to update the software of your Garmin chartplotter when installing this transducer pack to ensure compatibility and optimal performance. You can find the update instructions in your chartplotter’s user manual on support.garmin.com.

Using the GT36-TM and GT15M-IH transducers together provides a hybrid and versatile sonar solution. The GT36-TM transducer (transom-mounted) delivers clear, detailed images in shallow waters and at moderate speeds, while the GT15M-IH transducer (in-hull) is ideal for fiberglass hulls, offering protection against external damage and strong performance at high speeds without creating drag. This setup optimizes seabed and fish detection across various sailing conditions and hull types.

The Garmin GT36-TM and GT15M-IH transducer pack provides a hybrid sonar solution for versatile coverage. The GT36-TM transducer, designed for transom mounting, is built for ClearVü and SideVü functions, offering detailed views beneath and alongside your boat. The GT15M-IH transducer, designed for in-hull mounting, is a traditional sonar transducer that transmits signals through the hull, ideal for fiberglass hulls without drilling.

The GT36-TM transducer (transom-mounted) is compatible with all hull materials. The GT15M-IH transducer (in-hull) is specifically recommended for solid fiberglass hulls with a maximum thickness of 16 mm (5/8 in). It is not recommended for metal, wood, or sandwich (core) hulls.

To ensure optimal performance, you must update your Garmin chartplotter’s software when installing this transducer pack. Specific frequency compatibility (85 to 165 kHz for the GT15M-IH and UHD frequencies for the GT36-TM) will depend on your chartplotter or fishfinder model.

For optimal performance, the GT36-TM transducer must be mounted parallel to the waterline and extend 3.5 mm (0.125 in) below a fiberglass hull or 10 mm (0.375 in) below an aluminum hull. It must be installed at least 38 cm (15 in) from the propeller and away from any turbulence sources such as strakes, struts, fittings, or through-hulls. If the propeller rotates clockwise, mount the transducer on the starboard side; if it rotates counterclockwise, mount it on the port side.

The GT15M-IH transducer must be mounted in the bilge area, near the keel and the transom, on a solid fiberglass hull section without air gaps or core material. It should be installed as level as possible and must not be placed behind through-hull fittings or other protrusions, nor above a strake. A preliminary test phase before permanent installation is recommended to validate the location.

No, the GT15M-IH transducer is an internal transducer and does not require drilling the hull of your boat. It attaches to the inside of the hull, protecting it from external damage and eliminating drag.

The deadrise angle is critical for installing the GT15M-IH. The kit includes mounting brackets designed for different deadrise angles. You must measure the deadrise angle at the installation location and select the bracket that ensures the transducer is installed as horizontally as possible. The brackets are designed for deadrise angles of 0-3°, 4-8°, 9-16°, and 17-25°.

Yes, you can add an extension cable (Garmin part number 010-11617-42 or 010-11617-32) if the GT36-TM transducer cable is not long enough to reach the chartplotter. However, to avoid signal degradation, it is recommended not to extend the cable by more than 9 meters (30 feet).

It is imperative not to cut the probe cables. Cutting the transducer cables will void the warranty of your product.

The pack includes the GT36-TM transducer with its transom mount, as well as the GT15M-IH transducer with its internal mounting kit, which includes the tank and the necessary screws for installation.
