It is built around a low-profile bronze housing that extends less than 6.35 mm (0.25 in) below the hull, which helps it stay out of harm’s way on trailer bunks and rollers.\u003c\/p\u003e\u003cp\u003eThe 20° internal tilt is meant to match hull deadrise angles from 16° to 24° at the mounting location, so the sonar beam points straight down when the boat is on plane. At 50 kHz it uses a wide beam (22°) for deeper water tracking, and at 200 kHz it uses a narrow beam (6°) for better bottom detail and target separation.\u003c\/p\u003e\u003cp\u003eThis is a bronze-housed thru-hull style that suits fiberglass or wood hulls and is not a fit for aluminum hulls. Depth performance is rated to 549 m (1,800 ft) at 50 kHz and 244 m (800 ft) at 200 kHz, depending on water conditions, bottom type, installation quality, and sounder settings.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eTraditional dual-frequency sonar at 50\/200 kHz with 1 kW RMS power\u003c\/li\u003e\n\u003cli\u003eFixed 20° tilted element for hull deadrise angles from 16° to 24° at the install point\u003c\/li\u003e\n\u003cli\u003eDepth and fast-response water temperature sensing (no speed function)\u003c\/li\u003e\n\u003cli\u003eLow-profile bronze thru-hull housing that extends less than 6.35 mm (0.25 in) below the hull\u003c\/li\u003e\n\u003cli\u003eBeam coverage: 22° at 50 kHz for wider deep-water coverage, 6° at 200 kHz for tighter detail\u003c\/li\u003e\n\u003cli\u003eThru-hull cutout size of 95 mm (3-3\/4 in) for typical fiberglass or wood installations\u003c\/li\u003e\n\u003cli\u003e6-pin connector for systems that use the Garmin 6-pin transducer port\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eConfirm three things before ordering: your hull material, the deadrise where you plan to install, and the connector style at the sounder or sonar module. The 20° tilt is intended for 16° to 24° deadrise at the mounting location, and the bronze housing is intended for fiberglass or wood hulls.\u003c\/p\u003e\u003cp\u003eYour sonar must support 50\/200 kHz traditional sonar and a 1 kW transducer. If your Garmin device uses a different transducer port style than 6-pin, plan on using the correct adapter so the transducer can be connected without modifying the cable.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eThis is a thru-hull install that requires drilling a 95 mm (3-3\/4 in) hole and bedding the housing with marine sealant. The arrow on the top of the transducer should be aligned toward the keel or centerline so the internal element angle matches the hull’s deadrise.\u003c\/p\u003e\u003cp\u003eAfter launching, check for leaks right away and keep an eye on the install during the first hours in the water. Avoid pulling or carrying the transducer by the cable, and route the cable where it will not chafe or get pinched by panels, hatches, or rigging tubes.\u003c\/p\u003e\u003ch6\u003eOn-water use notes\u003c\/h6\u003e\u003cp\u003eThe 50 kHz channel is the go-to when you are pushing deeper water and want bottom tracking farther down, while 200 kHz tightens the beam for cleaner definition in shallower depths and around structure. Because the housing sits close to flush, it is a common choice for boats that run on plane and trailer often, where a larger fairing block would be vulnerable.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eKeep the face clean of growth and rinse it after saltwater use, especially if the boat sits in the water for extended periods. When cleaning around the transducer, stick with mild detergent and avoid solvent-based cleaners that can damage the transducer’s face and seals.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52269001638069,"sku":"QBP391527","price":1275.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298737_qbp391527.jpg?v=1771541402","url":"https:\/\/www.qualityboatparts.com\/products\/qbp391527","provider":"Quality Boat Parts","version":"1.0","type":"link"}
