This model offers direct integration with compatible Garmin chartplotters, providing real-time sonar data for navigation and fish detection.\u003c\/p\u003e\n\n\u003ch3\u003eHigh-definition transom-mount transducer\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eGT56UHD-TM\u003c\/strong\u003e is a dedicated transom-mount transducer designed for installation on the transom for user-friendly setup. Unlike thru-hull models requiring professional drilling through the hull, this transom-mount transducer attaches directly to the transom using a screw mount, providing a non-invasive mounting solution. The model operates optimally up to 34 knots and in waters without excessive turbulence. Its design includes splash protection and allows for pivot mounting to prevent damage from underwater obstacles.\u003c\/p\u003e\n\n\u003ch3\u003eCompatibility and system integration\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eGT56UHD-TM\u003c\/strong\u003e integrates with Garmin navigation units equipped with the appropriate connectors. Installation requires a standard transducer cable (extension available up to 9 m maximum to avoid signal degradation) and a software update for the chartplotter. This transducer belongs to Garmin’s GT56UHD series, positioned for high-definition sonar applications on small to medium recreational vessels. The model includes the transom mount, mounting screws, star washers, cable clamp, and cable entry cover.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation and maintenance considerations\u003c\/h3\u003e\n\u003cp\u003eOptimal installation of the \u003cstrong\u003eGT56UHD-TM\u003c\/strong\u003e requires a position parallel to the waterline, an extension depth of 3.5 mm below a fiberglass hull (or 10 mm below aluminum), and positioning at least 38 cm from the propeller. The transducer must be kept away from propeller turbulence and sources of electromagnetic interference. For vessels spending significant time in the water, an antifouling coating based on water is recommended after light sanding and cleaning with isopropyl alcohol. The transducer must never be exposed to acetone, which damages the plastic housing.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Rear panel","offer_id":55860658209108,"sku":"010-13073-00","price":267.69,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_440ee5ae-1649-4a8c-9bcf-8e65df593abc.jpg?v=1779195817","url":"https:\/\/skysat.fr\/en-gb\/products\/garmin-gt56uhd-tm-transom-mount-sonar-transducer","provider":"Skysat","version":"1.0","type":"link"}
