Airmar P155C-M In-Hull Medium Wide CHIRP With Bare Wire

The Airmar P155C-M In-Hull Medium Wide CHIRP With Bare Wire is the go-to transducer for anglers and boaters who demand real-time sonar performance without the complexity of through-hull installation. Designed for in-hull mounting directly against the inner hull, this medium-wide beam transducer delivers the clarity and coverage serious fishermen need to locate structure, thermoclines, and target species in freshwater and saltwater environments. Whether you're working shallow flats or probing deep offshore channels, this transducer bridges the gap between full-featured sonar capability and straightforward boat integration.

Airmar's CHIRP (Compressed High Intensity Radar Pulse) technology transmits a continuous frequency sweep across a broad spectrum, producing superior target separation and bottom detail compared to conventional single-frequency designs. The medium-wide beam pattern—typically 7° to 9°—balances wide coverage with precise target definition, making it ideal for mixed-use fishing where you're switching between shallow structure and deep water. The bare wire configuration offers direct connection flexibility, allowing integration with compatible fishfinders without unnecessary connector constraints. At just 2 lbs, the transducer is lightweight and simple to position, mounted flush against the inside of your hull with appropriate epoxy or sealant for optimal acoustic coupling.

In-hull mounting makes the P155C-M ideal for anglers unwilling to drill through the transom or keel, or for boats where through-hull access is compromised or impractical. This transducer pairs seamlessly with Airmar-compatible systems from major manufacturers, delivering CHIRP sonar performance without sacrificing hull integrity. Proper installation requires clean, solid contact between the transducer face and hull interior; air pockets or debris will degrade signal transmission. If you're upgrading an existing system or equipping a new rig with reliable, straightforward sonar capability, the bare wire configuration adapts to your existing wiring harness, making retrofit and troubleshooting hassle-free.
