It runs dual-band CHIRP with a low band of 42 to 65 kHz and a high band of 130 to 210 kHz, giving you wide coverage for finding fish and tracking bottom, plus a tighter beam when you want to pick structure apart.\u003c\/p\u003e\u003cp\u003eThis model is rated for depths up to 3,000 ft on the low band and up to 1,000 ft on the high band, with beamwidths of 25 to 16 degrees (low) and 10 to 6 degrees (high). The thru-hull uses a fairing that supports deadrise angles up to 20 degrees and helps keep the flow clean at speed.\u003c\/p\u003e\u003cp\u003eIt installs through a 30 mm (1-3\/16 in) hull hole and has a 121 mm (4.75 in) usable shaft length. The housing is specified for fiberglass or wood hulls, and the attached cable is 39 ft long for routing to the helm or to a sonar module.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e1 kW dual-band CHIRP: 42 to 65 kHz (low) and 130 to 210 kHz (high)\u003c\/li\u003e\n\u003cli\u003eDepth capability: up to 3,000 ft on low band and up to 1,000 ft on high band\u003c\/li\u003e\n\u003cli\u003eBeamwidth ranges: 25 to 16 degrees (low) and 10 to 6 degrees (high)\u003c\/li\u003e\n\u003cli\u003eBronze thru-hull housing with depth and fast-response water-temperature sensing\u003c\/li\u003e\n\u003cli\u003eFairing supports deadrise angles up to 20 degrees and helps performance at higher speeds (over 30 knots)\u003c\/li\u003e\n\u003cli\u003e30 mm (1-3\/16 in) installation hole size and 121 mm (4.75 in) usable shaft length\u003c\/li\u003e\n\u003cli\u003e12-pin connector for compatible Garmin sonar ports\u003c\/li\u003e\n\u003cli\u003e39 ft cable length for flexible routing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis transducer connects to Garmin chartplotters and sonar modules that accept a 12-pin transducer plug. Confirm your display or black box has the 12-pin transducer port before ordering, and plan the cable route so it stays clear of sharp edges, moving parts, and sources of heat.\u003c\/p\u003e\u003cp\u003eCommon pairings include GPSMAP 7600xsv series displays and the GSD 25 Premium Sonar Module when the system uses a 12-pin transducer connection. If your boat already has a different connector style, the connector type needs to match the sonar hardware you are using.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eAs a thru-hull, installation means drilling a 30 mm hole, bedding the stem, and orienting the fairing so the transducer face sits correctly in the water flow. Placement matters: pick a location with clean water under way, away from strakes, steps, intakes, and turbulence that can cause dropouts at speed.\u003c\/p\u003e\u003cp\u003eBecause this is a bronze housing and a permanent hull penetration, take the same care you would with any underwater fitting: proper sealant, correct torque, and a final leak check after launch. If you are not comfortable cutting a thru-hull, this is the kind of job many owners hand to a marine installer.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis is a strong fit for offshore fishing boats and cruisers that want one thru-hull transducer that can hold bottom in deeper water and still show detail when working reefs, wrecks, and bait schools. It is also commonly used on larger fiberglass hulls that spend time running at speed and need consistent sonar returns.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eKeep the transducer face clean of growth for consistent readings, and inspect the fairing and bedding periodically, especially after groundings or haul-outs. If you bottom-paint around it, use products and application methods that are safe for transducer acoustic windows, and avoid building paint thickness across the sensing face.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52269042827445,"sku":"QBP358921","price":2069.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298975_qbp358921.jpg?v=1771541576","url":"https:\/\/www.qualityboatparts.com\/products\/qbp358921","provider":"Quality Boat Parts","version":"1.0","type":"link"}
