{"product_id":"garmin-gt51m-th-transducteur-traversant","title":"GT51M-TH Thru-Hull Sonar Transducer - CHIRP\/ClearVü\/SideVü","description":"\u003cp\u003e\n    The \u003cstrong\u003eGarmin GT51M-TH thru-hull transducer\u003c\/strong\u003e is a sonar detection solution designed for robust and permanent installation on your vessel's hull. This thru-hull model is recommended for boats where consistent sonar performance without interference is critical, avoiding typical turbulence from transom-mounted transducers.\n\u003c\/p\u003e\n\u003ch3\u003eInstallation and compatibility of the Garmin GT51M-TH transducer\u003c\/h3\u003e\n\u003cp\u003e\n    Installing the \u003cstrong\u003eGarmin GT51M-TH\u003c\/strong\u003e requires precise procedures, detailed in the provided instructions, including hull preparation and securing with anti-rotation bolts. This method ensures increased stability of the device even in motion and prevents unwanted rotation. It is crucial to position the transducer in an area of clean water, away from propellers, keels, water intakes, or any turbulence source to optimize sonar signal quality. For hulls with a deadrise angle greater than 5°, using a fairing block is recommended to align the transducer parallel to the waterline, improving measurement accuracy. It is mandatory to update the firmware of the associated Garmin chartplotter to ensure compatibility and optimal performance with the \u003cstrong\u003eGT51M-TH\u003c\/strong\u003e.\n\u003c\/p\u003e\n\u003ch3\u003eSpecific mounting requirements for the Garmin GT51M-TH transducer\u003c\/h3\u003e\n\u003cp\u003e\n    Technical documentation highlights preparation steps for different hull types: fiberglass (with or without core) and metal, each requiring specific tools and techniques, such as using marine epoxy resin to seal fiberglass cores. Applying a marine sealant is essential to ensure a perfect seal between the transducer, the fairing block (if used), and the boat hull. The \u003cstrong\u003eGT51M-TH\u003c\/strong\u003e model, like other Garmin thru-hull transducers, is designed for durable and reliable integration, although details on specific frequencies or technologies (ClearVü, SideVü, CHIRP) are not directly provided in the installation documentation. The GT51M designation typically indicates advanced multi-beam capability, typical of high-end transducers from the brand.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Transom","offer_id":55860283244884,"sku":"010-01966-10","price":768.52,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_a25e84b2-6a53-46d0-84e8-feaff484ca16.jpg?v=1779191149","url":"https:\/\/skysat.fr\/en\/products\/garmin-gt51m-th-thru-hull-transducer","provider":"Skysat","version":"1.0","type":"link"}
