Get more coverage under your boat with Airmar’s unique wide-beam, high-frequency, Chirp-ready transducers. The high-frequency band operates across a range of 150 to 250 kHz and has a fixed 25° beam for all frequencies which results in superior resolution. The constantly wide beam provides twice the coverage and excellent fish arches on the display compared to most high-frequency, narrow-beam transducer options.
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 Sealcast™ 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. Antifreeze is the best medium to transmit through solid fiberglass and into the surrounding water. Designed for boats up to 11 m (36') with a solid-fiberglass hull.
