Get more coverage under your boat with Airmar’s unique wide-beam high-frequency Chirp-ready M285HW. The high-frequency band operates across a range of 150 to 250 kHz and has a fixed 25° beam for all frequencies. The high-frequency band delivers superior shallow-water performance bottom detail and fish-target separation. The constantly wide beam provides twice the coverage for detecting fish in the upper-water column and clear fish arches on the display compared to most high-frequency narrow-beam transducers. The high wide is the ideal choice for both inshore and pelagic fishing where resolution and maximum coverage are essential down to 152 m (500\').

The M285HW includes a plastic mounting base which is aligned to the centerline and secured inside the hull. Then it is filled with non-toxic antifreeze. The transducer is inserted into the base and adjusted for the proper deadrise offset ensuring the beam is shooting straight down for maximum echo returns. The eco-friendly coolant is the best medium to transmit through solid fiberglass and into the surrounding water. The major benefit of an in-hull transducer is no protruding features on the exterior of the hull making it the perfect choice for trailered or lifted boats. Designed for smaller boats up to 11 m (36\') with a solid-fiberglass hull.
