TM265C-LM-12F Transom Mount Transducer with 12-Pin Connector for Furuno TZT12F, TZT16F & TZT19FRely on Airmar's broadband transducers for the ultimate fishing mission! Whether you're a commercial fisherman, charter captain, or tournament angler, there's a new game in town. Traditional marine fishfinders operate at discreet frequencies such as 50 kHz and 200 kHz, use relatively short-duration pulses, and use narrowband sonar transducers. In contrast, CHIRP uses a precise sweep pattern of many frequencies within a long-duration transmits pulse from a broadband transducer, so the equivalent sound energy transmitted into the water is 10 to 1,000 times greater than a conventional marine fishfinder.Specifically designed for smaller boats (25'-40'), the TM265C-LM CHIRPS across the following bandwidths:Low & Medium-Frequency (LM)Low-Chirps from 42 kHz to 65 kHz, 25Adeg to 16Adeg beamwidthMedium-Chirps from 85 kHz to 135 kHz, 16Adeg to 11Adeg beamwidthMedium-frequency benefits include the ability to sound deeper than the high-frequency, along with better target resolution than the low-frequencyFeatures:8-Internal, Broadband Ceramic ElementsDepth & fast-response water-temperature sensorFishing Profile: Commercial and recreational inshore and offshore fishing (deep-water canyon and sea-mount tracking)Operating frequencies:Low-Chirps from 42 kHz to 65 kHzMedium-Chirps from 85 kHz to 135 kHzBeamwidth (Adjustable):Low-25Adeg to 16AdegMedium-24Adeg to 16Adeg10 m (33') cableThe depth and fast-response water-temperature sensor12 Pin Connector for use with Furuno TZT12F and TZT16F DisplaysUrethane transducer housing and stainless steel mounting bracketBoat Size: 8 m to 12 m (25' to 40')Hull Type: Fiberglass, wood, or metalExclusive Transducer IDThis product may not be returned to the original point of purchase.
