Description

Airmar PM Series Broad-Band CHIRP Pocket/Keel Mount Transducers

Airmar’s PM Series delivers high-performance dual- and single-band CHIRP transducers designed for precision fish detection, bottom detail, and versatility in commercial and recreational fishing applications. Pocket and keel mount designs provide easy installation on fiberglass hulls, ideal for boats from 8 m (25’) upwards. These transducers feature powerful broadband ceramic arrays, fast-response temperature sensors, and rugged bronze housings for durability and high sensitivity.

Models Available

PM265-LH (Low/High CHIRP)
PM265-LM (Low/Medium CHIRP)
PM275C-LHW (Low/High Wide CHIRP)

Key Features

Extensive frequency bandwidths covering 42–65 kHz low, 85–135 kHz medium, and 130–250 kHz high CHIRP frequencies
Power output: 1 kW
Bronze transducer housing for robustness in harsh marine environments
Urethane acoustic window for clear signal transmission
Depth and fast-response temperature sensing
Flat Edge design for pocket/keel mount on fiberglass hulls
Compatible with various deep-water and inshore fishing styles
Exclusive Xducer ID® technology for seamless sonar setup

Technical Highlights

PM265-LH: Narrow high-frequency beam for detailed structure target separation combined with deeper low frequency for depth penetration
PM265-LM: Medium frequency balances depth and coverage between low and high CHIRP bands
PM275C-LHW: Wide high-frequency beam enables broader coverage and sharper detail with large target images
Suitable for both commercial fishing and recreational angling, focusing on deep-water canyon and seamount tracking
