Whether you’re a commercial fisherman, charter captain, or tournament angler, there’s a new game in town. Traditional marine fish finders 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 transmit 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 fish finder.Specifically designed for small boats (25′-40′), the TM265LH Chirps across the following bandwidths:LH Model – Low Frequency 42-65 kHz/High Frequency 130-210 kHzSpecificationsLow frequency42-65 kHz (25 to 16 beamwidth)High frequency130-210 kHz (10 to 6 beamwidth)Boat Size8 m to 12 m (25 to 40)Boat typeOutboards, I/OHull typeFiberglass, Wood, MetalHull DeadriseUp to 28Acoustic WindowUrethaneWhat’s in the Box:TM265CLH-MMTransom Mount HardwareMMC-11R
