{"product_id":"airmar-b117-bronze-thru-hull-transducer","title":"Airmar B117 Bronze Thru-Hull Transducer","description":"\u003cp\u003eThe B117 series is the industry standard for low-profile, thru-hull transducers, featuring a high-performance 50\/200 kHz dual-frequency ceramic element. Designed for boats 8 meters (25') and up, this bronze housing unit is nearly flush with the hull, extending only 5mm (3\/16\") outside the surface to minimize drag. This makes it an ideal choice for center-console and trailered boats where streamlined performance is essential.\u003c\/p\u003e\n\n\u003cp\u003eEngineered for versatility, the dual-frequency element provides excellent target detail in shallow water at 200 kHz and superior bottom tracking in deep water at 50 kHz. The low-profile design is complemented by a right-angle cable exit, which offers a low headroom profile and protects the cable from damage if the transducer is stepped on. For installation ease, an included rubber washer allows the hull nut to be tightened securely against irregular hull surfaces.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-frequency performance: 50 kHz with a wide 45° beamwidth and 200 kHz with a 12° beamwidth\u003c\/li\u003e\n  \u003cli\u003eProvides depth and fast-response water temperature sensing\u003c\/li\u003e\n  \u003cli\u003e600 W power rating for reliable sonar returns\u003c\/li\u003e\n  \u003cli\u003eLow-profile bronze housing minimizes drag and is ABYC H-27 compliant\u003c\/li\u003e\n  \u003cli\u003eExcellent performance on fiberglass or wood hulls\u003c\/li\u003e\n  \u003cli\u003eRight-angle cable exit saves space and protects internal wiring\u003c\/li\u003e\n  \u003cli\u003eIdeal for leisure, yachting, and fishing applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Rating:\u003c\/strong\u003e 600 W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequencies:\u003c\/strong\u003e 50\/200 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth Range:\u003c\/strong\u003e 50 kHz: 235 m to 366 m (800' - 1200'); 200 kHz: 118 m to 206 m (400' - 700')\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBeamwidth:\u003c\/strong\u003e 45° (50 kHz) and 12° (200 kHz)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDeadrise Angle:\u003c\/strong\u003e Best performance through 7°; accommodates up to 12°\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter:\u003c\/strong\u003e 51 mm (2\")\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.9 kg (2.0 lb)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAcoustic Window:\u003c\/strong\u003e Urethane\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsable Shaft Length:\u003c\/strong\u003e 66.5 mm (2.62”)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eThis product may not be returned to the original point of purchase.
