It requires a Garmin sonar device or sonar module that accepts a 12-pin transducer and supports CHIRP on both the low and high bands.\u003c\/p\u003e\u003cp\u003eThe bronze housing is specified for fiberglass or wood hulls. On aluminum hulls, a different housing material is commonly used to avoid galvanic issues at the thru-hull.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eA thru-hull install needs access to both sides of the hull for drilling, bedding, and tightening the stem. The fairing is shaped to match the hull and aligned so water flows smoothly past the acoustic window.\u003c\/p\u003e\u003cp\u003eMost installs work best when the transducer is placed where the water stays solid and free of bubbles when running, away from strakes, intakes, and other fittings that introduce aeration. The fairing work matters on this style of transducer, so many owners have a yard or installer handle the cutout and final shaping.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThe wide high band suits anglers who want to cover more area under the boat while tracking bait and fish over reefs, wrecks, and open-water structure. The low band supports deeper drops when you run offshore or fish along the edge in several hundred feet and beyond.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eInspect the stem nut and bedding periodically, especially after the first trips and after haul-outs. Keep growth off the fairing and acoustic window, and avoid scraping that can gouge the urethane face.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":52269046661301,"sku":"QBP629296","price":2669.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1299218_qbp629296.jpg?v=1771541607","url":"https:\/\/www.qualityboatparts.com\/products\/qbp629296","provider":"Quality Boat Parts","version":"1.0","type":"link"}
