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, 25 to 16 beamwidthMedium-Chirps from 85 kHz to 135 kHz, 16 to 11 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 Elements; Depth & fast-response water-temperature sensor; Fishing Profile: Commercial and recreational inshore and offshore fishing (deep-water canyon and sea-mount tracking); Operating frequencies:; Low-Chirps from 42 kHz to 65 kHz; Medium-Chirps from 85 kHz to 135 kHz; Beamwidth (Adjustable):; Low-25 to 16; Medium-24 to 16; 10 m (33') cable; The depth and fast-response water-temperature sensor; 12 Pin Connector for use with Furuno TZT12F and TZT16F Displays; Urethane transducer housing and stainless steel mounting bracket; Boat Size: 8 m to 12 m (25' to 40'); Hull Type: Fiberglass, wood, or metal; Exclusive Transducer ID; This product may not be returned to the original point of purchase.
