Simrad XSONIC (Airmar) TM275LH-W Urethane. 42-65 kHz/150-250 kHz Dual Channel CHIRP TM Transducer The TM275LH-W is a urethane, transom-mounted CHIRP transducer, ideal for sportfishing and commercial vessels 8 m (25 ft) and up. This dual-channel transducer combines Low CHIRP frequencies to accurately track the bottom in deep water, with High CHIRP at a constant 25° beam width for the best resolution and coverage in the upper water column and in shallower depths. The TM275C-LHW CHIRP transom-mount transducer has 8 internal, broadband ceramic elements. The low-frequency can be chirped from 42 to 65 kHz while the high-frequency chirps from 130 to 210 kHz. The beamwidth is a wide 25° across all frequencies. Also included is a high-precision water-temperature sensor for accurate sea-surface temperature readings.
