Airmar M285C-HW CHIRP In-Hull With Bare Wire Mix-N-Match

The Airmar M285C-HW CHIRP In-Hull With Bare Wire Mix-N-Match transducer is purpose-built for anglers and boaters who demand reliable depth sensing and fish-finding capability without the commitment of a through-hull installation. This in-hull design makes it ideal for trailered boats, lifted vessels, or situations where hull penetration isn't practical or desired. Whether you're fishing inland lakes, coastal bays, or making the jump to offshore waters, this CHIRP-ready transducer delivers the sonar performance serious anglers expect at a fraction of the installation complexity.

Built on Airmar's proven CHIRP technology, the M285C-HW operates in the high-frequency 150–250 kHz range, providing exceptional detail for both shallow inshore structure and deeper offshore applications. CHIRP (Compressed High Intensity Radar Pulse) sends a continuous sweep of frequencies rather than a single pulse, resulting in superior target separation, reduced noise, and clearer bottom definition—critical advantages when distinguishing baitfish from bottom composition or locating suspended gamefish. The bare wire mix-and-match connector system gives you complete flexibility in cable routing and transducer integration, allowing custom installation that adapts to your specific boat layout. At 8 lbs, it's lightweight enough for easy handling while maintaining the rugged construction that survives seasons of freshwater and saltwater use.

This transducer suits boaters running depth-only sonar systems or those upgrading to CHIRP capability on existing equipment. The in-hull mounting approach eliminates hull drilling and potential water intrusion risks—a significant advantage for fiberglass, aluminum, or composite hulls where integrity matters. Professional guides, tournament anglers, and recreational fishermen working shallow to moderate depths will appreciate the high-frequency resolution that reveals bottom structure, thermoclines, and baitfish schools with precision. Installation requires dry hull contact and proper coupling medium, but once mounted, delivers years of dependable service in freshwater lakes, rivers, and coastal saltwater environments where reliable sonar makes the difference between a good day and a great one.
