Airmar M285HW High Wide Chirp In-Hull 1KW - Requires Mix and Match Cable

The Airmar M285HW High Wide Chirp In-Hull 1KW transducer is purpose-built for serious anglers who demand reliable, economical sonar performance in both offshore and freshwater environments. This in-hull transducer eliminates the need for through-hull drilling, making it ideal for retrofit installations or boats where hull penetration isn't practical. Whether you're targeting deep-water structure or shallow spawning beds, the M285HW delivers the frequency range and beam width needed to read water column dynamics and locate fish with confidence.

Operating at 1 kilowatt of power across a high frequency band of 150–250 kHz with a fixed wide 25-degree beam pattern, this CHIRP transducer provides excellent target separation and bottom definition across varying depths and bottom compositions. CHIRP technology sweeps across the frequency range rather than pinging at a single frequency, yielding superior image clarity and reducing clutter—critical when distinguishing baitfish from gamefish or identifying hard bottom transitions. The compact 8 x 5 x 12-inch footprint and 4.75-pound weight make installation straightforward in tight mounting spaces, whether mounted in the bilge or against the hull interior using marine epoxy or transom brackets.

Anglers and boaters running GPS-integrated fish finders will appreciate the M285HW's compatibility with modern sonar systems that support CHIRP frequencies. Note that this transducer requires a Mix and Match cable—verify connector type and length before purchase to ensure proper integration with your existing chartplotter. In-hull mounting works best in freshwater and calm-water applications; offshore anglers in heavy seas may prefer through-hull options for peak sensitivity, though this model delivers solid real-time performance for recreational and semi-professional fishing operations seeking budget-conscious, reliable sonar without sacrificing frequency range.
