Airmar P155C-M In-Hull Medium Wide CHIRP With Humminbird 14-Pin

The Airmar P155C-M In-Hull Medium Wide CHIRP With Humminbird 14-Pin transducer is purpose-built for serious bass and walleye anglers who demand reliable, high-resolution sonar in both freshwater and saltwater environments. As an in-hull puck-style transducer, it mounts flush within your hull without through-hull penetration, making it ideal for anglers who want to eliminate potential leak points while maintaining maximum performance. This transducer integrates seamlessly with Humminbird fish finders via the included 14-pin connector, delivering the modern CHIRP technology that has become standard in professional tournament fishing and dedicated freshwater angling.

CHIRP (Compressed High Intensity Radar Pulse) sonar transmits a continuous sweep of frequencies rather than a single frequency, producing exceptional target separation, reduced noise, and superior bottom definition in real-world conditions. The medium-wide beam angle of the P155C-M provides optimal coverage for structure fishing and suspended fish detection without excessive cone width that can cloud target identification. At just 2 pounds, this compact puck design minimizes weight distribution concerns and fits easily into most modern bass and walleye boat installations. The wideband frequency range ensures consistent performance across varying water conditions, from murky reservoirs to crystal-clear northern lakes, giving you confidence in your sonar data regardless of season or location.

This transducer is the ideal upgrade for Humminbird-equipped boats seeking enhanced sensitivity and target resolution without replacing your existing sonar head unit. The 14-pin connector ensures plug-and-play compatibility with compatible Humminbird HELIX and ONIX series models, eliminating the need for adapter cables or custom wiring. Installation is straightforward for anglers comfortable with basic boat maintenance—mounting inside the hull requires only a clean, flat surface and proper silicone sealant to ensure acoustic coupling. Whether you fish tournaments, guide clients, or pursue trophy walleye year-round, the P155C-M delivers the clarity and reliability that separate fish-finding success from frustration on the water.
