GT56UHD-TH skersinė sonda – UHD ClearVü/SideVü

Yes, the Garmin GT56UHD-TH depth sounder is designed to be compatible with Garmin chartplotters. However, it is imperative to update your Garmin chartplotter’s software when installing this depth sounder 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 supplied with the unit and must be installed to prevent the transducer 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 transducer's orientation.

Location choice is essential for optimal performance and must be done carefully. Here are the main considerations:

Non-turbulent water: The transducer must be mounted in an area where the water is clean, 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 engine shaft.For single-propulsion boats: do not mount in the propeller path to avoid cavitation.For twin-propulsion boats: if possible, between the propulsions.Specific hull types:Planing hulls: in front of the first chine.Displacement hulls: approximately 1/3 of the waterline length from the bow, and 150 to 300 mm to the side of the centerline.Long keeled hulls: slightly angled toward the bow, parallel to the centerline.Fin keeled hulls: 25 to 75 cm in front of the keel and max 10 cm to the side of the centerline.Avoid impacts: Do not mount in a location where it could be struck during launching, beaching or storage.The transducer must be mounted parallel to the bow-stern axis of your vessel.

A fairing block is an accessory that positions the transducer parallel to the waterline, improving sonar data accuracy. 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 precisely.

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 sits in clean, non-turbulent water, which minimizes interference and ensures clearer and more accurate sonar images. This is particularly beneficial for ultra-high-definition scanning functions.

For the installation of the GT56UHD-TH transducer, it is recommended to use a flexible, fast-curing marine sealant specifically designed for below-the-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 intrusion.
