M285HW Chirp In-Hull 1kw TransducerRequires Mix and Match CableThe M285HW, is a 1kW, economical Chirp transducer designed for offshore fishing and freshwater anglers. Operating at the high frequency range of 150-250kHz and a fixed wide beam of 25 degrees, these transducers reveal ultra-clear target resolution in shallow,murky waters at shallow to medium depths(up to 700 feet*).The transducer includes a plastic housing which is secured inside the hull of the boat and is filled with Eco-friendly anti-freeze.
