Sonda GT56UHD-TH - transduktor za UHD ClearVü/SideVü

Yes, the Garmin GT56UHD-TH transducer is designed to be compatible with Garmin chartplotters. However, it is mandatory to update your Garmin chartplotter's software when installing this transducer to ensure compatibility and optimal performance. Update instructions are typically found in your chartplotter's user manual on support.garmin.com.

Anti-rotation bolts are crucial for the safety and performance of the GT56UHD-TH depth sounder. They are included with the unit and must be installed to prevent the depth sounder from rotating when the boat is underway. Failure to install them could damage your vessel and compromise the reliability of sonar readings by altering the depth sounder's orientation.

The choice of mounting location is essential for optimal performance and must be done carefully. Here are the main considerations:

Non-turbulent water: The transducer must be installed in an area where water flow is smooth, free of air bubbles and turbulence caused by frames, reinforcements, fittings, scuppers, or water discharges.Distance from engine/propeller:For outboard and sterndrive boats: in front of and near the engine(s).For inboard boats: in front of and far from the propeller and propeller shaft.For single-propulsion boats: do not install in the propeller’s wash to avoid cavitation.For twin-propulsion boats: if possible, between the propellers.Specific hull types:Planing hulls: in front of the first chine.Vee hulls: slightly angled toward the bow, parallel to the centerline.Fin keel hulls: 25 to 75 cm ahead of the keel and max 10 cm to the side of the centerline.Displacement hulls: about 1/3 of the waterline length from the bow, and 150 to 300 mm to the side of the centerline.Avoid impacts: Do not install in an area where it could be struck during launching, beaching, or storage.The transducer must be mounted parallel to the fore-aft axis of your vessel.

A fairing block is an accessory that positions the transducer parallel to the waterline, improving the accuracy of sonar data. You must measure the deadrise angle of your boat’s hull at the installation location. If this angle exceeds 5°, using a fairing block is recommended for optimal transducer mounting.

Hole dimensions to drill in the hull vary slightly depending on hull type:

For the stem hole (central hole for the transducer stem):
Fiberglass hulls (with or without core): 25 mm (1 inch) diameter.
Metal hulls: 32 mm (1 1/4 inch) diameter.
For the anti-rotation bolt holes:
Fiberglass hulls (with or without core): 9 mm (3/8 inch) diameter.
Metal hulls: 13 mm (1/2 inch) diameter.
It is recommended to use the mounting template provided in the product box to mark hole locations accurately.

The main advantage of a through-hull transducer like the Garmin GT56UHD-TH is its ability to provide optimal and reliable sonar readings. By being installed directly through the hull, it is immersed in clean, non-turbulent water, which minimizes interference and ensures better clarity and accuracy of sonar images. This is particularly beneficial for ultra high definition scanning functions.

For installing the GT56UHD-TH transducer, it is recommended to use a flexible, fast-curing marine sealant specifically designed for below-waterline applications. This type of sealant ensures a strong and durable watertight seal between the transducer (or the fairing block, if used) and your boat's hull, preventing water ingress.
