It is a 600 W unit with a 45-degree beam at 50 kHz and a 12-degree beam at 200 kHz, and it is specified for depth performance from 800 to 1,200 ft.\u003c\/p\u003e\u003cp\u003eIt uses a low-profile housing that extends about 5 mm (3\/16 in.) outside the hull and is intended for fiberglass and wood hulls. The mounting location should have 0 to 7 degrees of deadrise, and installation requires a 2 in (51 mm) thru-hull hole; it should not be used on metal hulls.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eTraditional dual-frequency sonar: 50\/200 kHz at 600 W for depth with water-temperature sensing\u003c\/li\u003e\n\u003cli\u003eBeam coverage options: 45-degree beam at 50 kHz and 12-degree beam at 200 kHz\u003c\/li\u003e\n\u003cli\u003eLow-profile bronze housing with about 5 mm (3\/16 in.) extending outside the hull to keep drag down at speed\u003c\/li\u003e\n\u003cli\u003eIntended for fiberglass and wood hulls; not suitable for metal hull installations\u003c\/li\u003e\n\u003cli\u003eFits 0 to 7 degrees of deadrise at the mounting location\u003c\/li\u003e\n\u003cli\u003eRequires a 2 in (51 mm) thru-hull hole and inside access for the retaining nut and cable routing\u003c\/li\u003e\n\u003cli\u003e8-pin connection with an attached 39 ft cable for routing to the sounder or sonar module\u003c\/li\u003e\n\u003cli\u003eDepth and temperature only, with no speed sensor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis transducer connects to Garmin sonar equipment that accepts an 8-pin traditional transducer plug. If the sounder has a 6-pin transducer port, an adapter cable is required for connection.\u003c\/p\u003e\u003cp\u003eBecause it is a 0-degree, low-profile thru-hull style, confirm the deadrise angle at the planned mounting spot is within the 0 to 7 degree range. Plan for a 2 in (51 mm) hull penetration and enough clearance on the inside to tighten the hardware and route the cable without sharp bends.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThru-hull transducers need a clean-water location for consistent readings, so pick a spot that stays submerged and avoids turbulent flow from strakes, steps, intakes, and other thru-hulls. Route the cable away from ignition wiring and high-current runs where possible, and leave a service loop so connections are not strained.\u003c\/p\u003e\u003cp\u003eUse proper marine sealing practices for the hull penetration and recheck the retaining nut after the first few outings, especially on boats that see heavy vibration or frequent trailering.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis is a straightforward match for boats that want dependable bottom tracking and water temperature while running at speed, including coastal cruising and fishing setups using traditional 50\/200 kHz sonar. It fits well when you have room for a thru-hull install and want the low-profile exterior shape that keeps drag and snag risk down.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eKeep the face of the transducer free of marine growth for accurate depth and temperature readings. During routine bottom checks, inspect the outside surface for fouling and confirm the inside hardware and bedding remain secure and dry.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52269102170293,"sku":"QBP731637","price":374.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298859_qbp731637.jpg?v=1771541887","url":"https:\/\/www.qualityboatparts.com\/products\/qbp731637","provider":"Quality Boat Parts","version":"1.0","type":"link"}
