{"product_id":"garmin-gt51m-thp-sonde-traversante","title":"GT51M-THP Transom-Mount Sonar - CHIRP\/ClearVü\/SideVü Pair","description":"\u003cp\u003e\n    The Garmin GT51M-THP \u003cstrong\u003etransom-mount sonar\u003c\/strong\u003e is a cutting-edge solution for Garmin CHIRP sonar systems. Designed for optimal installation, it delivers superior performance by eliminating interference and turbulence commonly encountered with transom-mount transducers. Its transom-mount design is particularly well-suited for fiberglass hulls (with or without core) and metal hulls, offering installation flexibility for a wide range of vessels.\n\u003c\/p\u003e\n\u003ch3\u003eInstallation and acoustic performance\u003c\/h3\u003e\n\u003cp\u003e\n    GT51M-THP installation is detailed to ensure perfect integration and long-term reliability. It requires precise drilling of holes for the main stem and anti-rotation bolts, essential for keeping the transducer in place even at high speeds, preventing potential hull damage. The use of a fairing block is recommended if the hull’s deadrise angle exceeds 5°, allowing the transducer to be positioned parallel to the waterline for enhanced sonar accuracy. This technical approach minimizes cavitation and ensures clean water flow over the transducer element, maximizing the efficiency of ClearVü, SideVü, and CHIRP technologies.\n\u003c\/p\u003e\n\u003ch3\u003eRobust design and system integration\u003c\/h3\u003e\n\u003cp\u003e\n    The installation process emphasizes hull preparation, including sanding, cleaning, and applying a fast-curing, flexible marine sealant for flawless waterproofing below the waterline. Anti-rotation bolts and nut-secured mounting (with rubber and nylon washers) ensure robust mechanical stability. Unlike transom-mount transducers such as the GT20-TM or GT22HW-TM, the GT51M-THP’s transom-mount design provides a fixed and stable position, critical for acquiring detailed and consistent sonar data, particularly for precision bathymetry and SideVü underwater structure detection. It is imperative to update the Garmin display software during installation for optimal compatibility and performance.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Deck-through fitting","offer_id":55860284064084,"sku":"010-01966-11","price":1038.69,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_f32760f7-0e25-4760-8398-c2e6a812bd0e.jpg?v=1779191168","url":"https:\/\/skysat.fr\/en-gb\/products\/garmin-gt51m-thp-transom-mount-sonar","provider":"Skysat","version":"1.0","type":"link"}
