Medium-band CHIRP is a practical choice when you want clear fish and structure returns in mid to deeper water without narrowing the coverage as much as high frequency.\u003c\/p\u003e\u003cp\u003eThe housing mounts close to flush on the outside of the hull, and the internal tilt keeps the element level when installed on hull deadrise between 16 and 24 degrees.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e1 kW single-band Medium CHIRP element (85 to 135 kHz)\u003c\/li\u003e\n\u003cli\u003eFixed 20 degree Tilted Element corrects for 16 to 24 degree hull deadrise without a fairing block\u003c\/li\u003e\n\u003cli\u003eDepth plus fast-response water-temperature sensing at the transducer\u003c\/li\u003e\n\u003cli\u003eMedium-band beamwidth 16 to 11 degrees with a maximum depth rating of 457 m (1,500 ft)\u003c\/li\u003e\n\u003cli\u003eStainless steel thru-hull housing with a low-profile exterior\u003c\/li\u003e\n\u003cli\u003eBlack 9-pin connector with 10 m (33 ft) cable\u003c\/li\u003e\n\u003cli\u003eInstallation hole size: 95 mm (3-3\/4 in) for fiberglass or wood hulls, 105 mm (4-1\/8 in) for metal hulls\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis is the 20 degree version of the SS175M, intended for hull bottoms that measure roughly 16 to 24 degrees of deadrise at the mounting location. If the deadrise is outside that range, the element will not sit level and performance can drop.\u003c\/p\u003e\u003cp\u003eThe stainless housing is suitable for fiberglass, wood, aluminum, and steel hulls. The required cutout depends on hull material, and metal hulls use the larger 105 mm (4-1\/8 in) hole size, so measure before committing to the location.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eBecause it is a thru-hull, the inside clearance matters as much as the outside. Make sure there is room for the stem and nut, and that you can tighten it square to the hull without interference from stringers, tanks, or liners.\u003c\/p\u003e\u003cp\u003ePick a spot that stays in clean water flow when the boat is on plane and that is away from steps, strakes, intakes, and trailer bunks. The stem uses a 3-3\/4 in - 4 thread, and the sealing surface should be bedded with a marine sealant appropriate for your hull material.\u003c\/p\u003e\u003ch6\u003eSonar integration\u003c\/h6\u003e\u003cp\u003eThe attached cable terminates in a 9-pin plug. If your display or sonar module uses a different transducer port, an adapter may be required. Confirm that your sonar source supports 1 kW CHIRP and the Medium band (85 to 135 kHz) so the transducer can be driven correctly.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis transducer is a good match for anglers and cruisers who spend time in shallow through mid-depth water and want returns that stay readable as speed comes up. Medium CHIRP also works well when you are looking for bottom detail around structure without switching between separate low and high elements.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eCheck the exterior face for marine growth and clean it with mild soap and a soft pad. Periodically inspect the cable run for chafe, and keep tight bends out of the cable near the connector.\u003c\/p\u003e\u003cp\u003eIf you bottom paint the hull, avoid getting heavy paint build-up on the acoustic face unless the coating is specifically approved for transducer use.\u003c\/p\u003e","brand":"Simrad","offers":[{"title":"Default Title","offer_id":52269683474613,"sku":"QBP497407","price":1463.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1299827_qbp497407.jpg?v=1771545218","url":"https:\/\/www.qualityboatparts.com\/products\/qbp497407","provider":"Quality Boat Parts","version":"1.0","type":"link"}
