Sada sond GT36-TM a GT15M-IH

This pack includes two separate transducers for versatile sonar coverage. It includes 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 transmission power of 600 W (RMS). It can reach a maximum depth of 549 meters (1800 feet), depending on water conditions. Its operating frequencies range from 85 to 165 kHz, with the exact range depending on your chartplotter or depth sounder model. Its 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 (core) hulls.

For optimal performance, the GT36-TM transducer must be mounted on the transom, 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 areas of turbulence 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 deadrise angle of the hull 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 chines that could create turbulence.

No, it is strongly advised not to cut the transducer cable. Cutting the transducer cable voids your warranty. If the cable is too long, it is recommended to coil it carefully or use a specific Garmin cable extension for the GT36-TM transducer (part numbers 010-11617-42 or 010-11617-32), without exceeding 9 meters (30 feet) to avoid signal degradation.

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

The combined use of GT36-TM and GT15M-IH transducers provides a hybrid and versatile sonar solution. The GT36-TM transducer (transom-mounted) delivers clear and 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 good performance at high speeds without creating drag. This pack optimizes seabed and fish detection in 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, mounted on the transom, is designed for ClearVü and SideVü functions, offering detailed imaging below and to the sides of your boat. The GT15M-IH transducer, installed internally, is a traditional sonar transducer that transmits the signal 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 up to 16 mm (5/8 in) thick. It is not recommended for metal, wood, or sandwich (core) hulls.

To ensure optimal performance, you must update the software of your Garmin chartplotter when installing this transducer pack. The specific frequency compatibility (85 to 165 kHz for the GT15M-IH and UHD frequencies for the GT36-TM) will depend on your chartplotter or depth sounder 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 stringers, struts, fittings, or through-hull fittings. 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 flat as possible and must not be placed behind water intakes 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 through your boat’s hull. It is mounted inside the hull, which protects it from external damage and eliminates drag.

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

Yes, you can add a cable extension (Garmin part numbers 010-11617-42 or 010-11617-32) if the cable of your GT36-TM transducer 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 cables of the transducers. Cutting the cables of the transducers 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, including the tank and the necessary screws for installation.
