As Chirp continues to redefine recreational fishing, AIRMAR has expanded the lineup of single band transducers to satisfy the growing demand for this game changing technology. The 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. The transducer is inserted into the housing and adjusted for the proper dead rise offset,insuring the beam is shooting straight down. The liquid provides the best medium to transmit through the fiberglass and into the surrounding water. The benefits to the in-hull transducer are that there are 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 25’ with solid core,fiberglass hulls.

Expert Overview

The Airmar M285C-HW CHIRP In-Hull Transducer with Navico 9-Pin Mix-N-Match is an IT hardware component designed for integration into marine electronics systems, specifically for depth-only fishfinding applications. This 1 kW, high-frequency (150-250kHz) transducer provides a fixed 25-degree beamwidth, suitable for both offshore and inshore environments. It is engineered for boats up to 25 feet with solid core, fiberglass hulls, and is particularly beneficial for trailered or lifted boats due to its in-hull mounting, which eliminates external protrusions. The M285C-HW-9N model utilizes a liquid-filled urethane housing to transmit through the hull, offering target resolution in depths up to 700 feet. This product addresses the need for reliable depth data without external hull modifications, making it a practical choice for IT buyers managing marine hardware installations where hull integrity and trailering convenience are priorities.
