This model is distinguished by its stainless steel construction, ensuring compatibility with a variety of hull materials, including fiberglass, wood, composites, aluminum, and steel. Its specific \"0-degree\" 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\u003eIntegration and Hull 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 risks, 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 waterproofing. Installing this sonar 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 sonar’s top arrow 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 sonar 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 correct implementation, perfect waterproofing, and to avoid damage to the device or the vessel. Applying flexible, fast-curing marine sealant is essential for the waterway path. Additionally, updating the Garmin chartplotter’s software after installation is necessary 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":"0 degree","offer_id":55860431880532,"sku":"010-02868-00","price":715.18,"currency_code":"USD","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-us\/products\/garmin-gt15m-thf-through-hull-sonar-0-degree","provider":"Skysat","version":"1.0","type":"link"}
