Product Overview

Covers popular fishing frequency of 50kHz and 200kHz plus everything else in the 40kHz to 60kHz and 130kHz to 210kHz bandwidths

Rely on Airmar’s broadband transducers for your ultimate fishing mission. Whether you’re a commercial fisherman, charter captain, or tournament angler, there’s a new game in town! CHIRP transducers enable bottom detection down to 10,000’ with five to ten times greater detail and resolution so precise it’s possible to distinguish between individual baitfish, game fish, and underwater structures.

The 1kW, flush-mount, Tilted Element transducer is perfect for fast, trailered, tournament sportfishing vessels that cannot have a High-Performance Fairing. The flush-mounted, bronze housing protrudes less than a quarter inch (6.35 mm) outside your hull and can sit on trailer rollers and bunks with no damage. The ceramic arrays are tilted 20° inside the housing giving you the perfect vertical beam with maximum energy on what is directly below your boat.
