Its stainless steel housing ensures enhanced durability in marine environments, allowing installation on fiberglass, wood, composite, aluminum, or steel hulls.\n\u003c\/p\u003e\n\u003ch3\u003eInstallation and versatility of the GT17M-THF sonar\u003c\/h3\u003e\n\u003cp\u003e\n    This model features a 12° internal angle, specifically adapted to compensate for hull drift angles ranging from 6° to 16°, ensuring optimal orientation of the transducer element for precise sonar performance. When installing on aluminum or steel hulls, the use of the included galvanic isolation components is mandatory to prevent corrosion and maintain hull watertight integrity. Installation requires specific tools, such as 98 mm (3 7\/8 in) hole saws for fiberglass and 101 mm (4 in) for metal, along with a flexible, fast-curing marine sealant for watertight sealing below the waterline.\n\u003c\/p\u003e\n\u003ch3\u003eRecommendations and maintenance for the Garmin GT17M-THF sonar\u003c\/h3\u003e\n\u003cp\u003e\n    Garmin recommends professional installation by a qualified technician to ensure optimal performance and avoid damage to the device or vessel. A software update for the Garmin chartplotter is required after installing this device. Cabling must be routed carefully, away from potential interference sources such as engines and other wiring, using grommets to protect the cable when passing through bulkheads. For maintenance, applying water-based antifouling paint is an option to prevent fouling, and it is critical to check for leaks before leaving the boat in the water for an extended period. The \u003cstrong\u003eGarmin GT17M-THF 12° through-hull sonar\u003c\/strong\u003e stands as a reliable technical choice for demanding navigators, requiring careful installation but offering robustness and extended compatibility compared to transom-mounted or internal transducers, which are less suited to all hull configurations and marine conditions.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"12 degrees","offer_id":55860452360532,"sku":"010-02930-01","price":1052.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_be13740a-b741-4b18-b9d1-6c3346f11079.jpg?v=1779193685","url":"https:\/\/skysat.fr\/en-us\/products\/garmin-gt17m-thf-12-degrees-through-hull-sonde","provider":"Skysat","version":"1.0","type":"link"}
