Detailed instructions cover specific considerations for outboard and inboard motor vessels, stepped hulls, full-keel hulls, fin-keel hulls, and displacement hulls. It is imperative to mount the transducer in an area of clean water, free from turbulence generated by strakes, struts, fittings, or water intakes\/outlets. The transducer must be positioned parallel to the fore-aft axis of the vessel. If the hull's deadrise angle exceeds 5°, the use of a fairing block is recommended to ensure the transducer is parallel to the waterline, optimizing sonar accuracy.\n\u003c\/p\u003e\n\u003ch3\u003eTechnical Installation and Integration\u003c\/h3\u003e\n\u003cp\u003e\n    The GT56UHD-THP installation procedures are suited for fiberglass hulls (with or without core) and metal hulls. They involve drilling precise holes for the transducer shaft and included anti-rotation bolts, essential for preventing device rotation during movement. Rigorous application of marine sealant is critical for perfect waterproofing, and for fiberglass core hulls, the use of high-quality marine epoxy resin is required to seal the exposed core. The mounting kit includes anti-rotation bolts, washers (24 mm rubber, 26 mm nylon, 8 mm), and nuts (35 mm for the hull, M8) for secure and robust internal hull mounting. This installation method ensures increased reliability and durable integration in the marine environment, offering a more permanent and often higher-performance alternative to transom-mount solutions.","brand":"Garmin","offers":[{"title":"","offer_id":55860398653780,"sku":"010-02732-11","price":1222.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_eacc399a-fe53-4a1f-bc3a-555f4c30647c.jpg?v=1779192791"},{"product_id":"garmin-gt12m-thf-sonde-traversante-0-degre","title":"Sonde GT12M-THF 0° - traversante CHIRP moyenne fréquence","description":"\u003cp\u003e\n    Le transducteur traversant \u003cstrong\u003eGarmin GT12M-THF\u003c\/strong\u003e de 0 degré est conçu pour une installation sur les coques en fibre de verre, en bois ou en composite.
