This model stands out with its stainless-steel construction, ensuring compatibility with a wide range of hull materials, including fiberglass, wood, composites, aluminum, and steel. Its specific \"0°\" design is optimized for deadrise angles ranging from 0 to 5 degrees, guaranteeing optimal sonar performance and accurate seabed readings.\n\u003c\/p\u003e\n\n\u003ch3\u003eHull Integration and Materials\u003c\/h3\u003e\n\u003cp\u003e\n    Unlike models such as the GT12M-THF, which uses brass and is unsuitable for aluminum or steel hulls due to galvanic corrosion risk, the GT15M-THF in stainless steel is specifically designed for these environments. For installations on metal hulls (aluminum or steel), the use of the included galvanic isolation components is mandatory to prevent corrosion and ensure watertight integrity. Installing this fishfinder requires a methodical approach, with specific drilling diameters: 73 mm (2 7\/8 in) for fiberglass hulls and 75 mm (3 in) for metal hulls. Precise alignment of the top arrow of the fishfinder toward the keel is critical so that the internal angle of the transducer element matches the vessel’s deadrise angle.\n\u003c\/p\u003e\n\n\u003ch3\u003ePerformance and Installation Precautions\u003c\/h3\u003e\n\u003cp\u003e\n    For optimal performance, the fishfinder must always be used while submerged. Operating it in air can lead to overheating and damage. Garmin recommends installation by a qualified professional to ensure proper implementation, perfect watertight sealing, and to avoid damage to the device or the vessel. Applying a flexible, fast-curing marine sealant is essential for the fairing. Additionally, updating the Garmin chartplotter’s software after installation is required to access all features. It is also important to note that the transducer cable must not be cut or spliced unless the sonar module requires bare-wire connections, to avoid voiding the warranty.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"","offer_id":55860431880532,"sku":"010-02868-00","price":657.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_2ba598eb-ff1b-4245-b48d-44b0403454ac.jpg?v=1779193323","url":"https:\/\/skysat.fr\/en-bh\/products\/garmin-gt15m-thf-through-hull-sonar-0-degree","provider":"Skysat","version":"1.0","type":"link"}
