This bronze transducer integrates depth, speed, and temperature functions, providing a compact solution that minimizes the number of hull penetrations required. Operating at 50 kHz and 200 kHz frequencies, it allows bottom detection up to 366 meters at 50 kHz and 213 meters at 200 kHz, making it suitable for mid-depth navigation and coastal fishing applications.\n\u003c\/p\u003e\n\n\u003ch3\u003eAcoustic Performance and Accuracy\u003c\/h3\u003e\n\u003cp\u003e\n    With a 600W RMS power output, the Airmar B744V transducer delivers high-quality data for various inland and coastal fishing applications. The 45° beam at 50 kHz provides wide coverage for detecting fish schools, while the 12° beam at 200 kHz offers precise bottom structure definition and better target separation. The speed range ensures reliable measurements even at high speeds, with excellent results up to 30 knots (34 MPH), a key advantage for planing hulls where signal stability is critical.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegration and Installation\u003c\/h3\u003e\n\u003cp\u003e\n    The B744V is a bronze through-hull transducer suitable for fiberglass or wooden hulls; it must not be installed on metal hulls due to the risk of electrolytic corrosion. Installation requires a 51 mm (2-inch) hole and the mandatory use of the high-performance fairing block provided. This fairing block ensures laminar water flow around the sensor, improving performance at high speeds and allowing stable readings up to 24° of deadrise angle. The 8-pin connector ensures direct compatibility with compatible Garmin systems, facilitating integration into the vessel’s existing electronics ecosystem.\n\u003c\/p\u003e\n\n\u003ch3\u003eDesign and Maintenance\u003c\/h3\u003e\n\u003cp\u003e\n    Equipped with a patented self-sealing retractable system, the transducer allows removal of the paddlewheel insert for cleaning or maintenance without requiring the boat to be dry-docked. Fins on the paddlewheel cavity optimize speed accuracy in cross-currents. For optimal watertightness, all O-rings must be lubricated, and a safety lanyard must be attached to prevent the insert from dislodging. For thicker hulls or more pronounced deadrise angles, the B744VL version with a longer shaft is available, offering greater installation flexibility compared to this standard model for specific boat configurations.\n\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":55860543848788,"sku":"010-10183-22","price":495.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_46edef3b-647c-44cf-954e-34e451e4e306.jpg?v=1779194193","url":"https:\/\/skysat.fr\/en-us\/products\/garmin-airmar-b744v-bronze-through-hull-transducer-600w-50-200khz","provider":"Skysat","version":"1.0","type":"link"}
