Thru-Hull Chirp Transducers Unlock the true potential of your fishfinder with the superior quality and performance of an AIRMAR Chirp-ready transducer. B265LH screenshot courtesy of Furuno The Benefits of AIRMAR’s Chirp-ready Transducers • One broadband transducer covers up to 117 kHz of bandwidth – greater opportunities to detect fish in the water column Superior resolution – precise separation between baitfish and gamefish represented on the display with crisp images Enhanced bottom fishing – resolve targets close to the bottom or near structure/wrecks Amazing detail – recognize haloclines and thermoclines Improved signal to noise ratio – find fish and track bottom at high boat speeds AIRMAR®, DEFINING CHIRP TECHNOLOGY. Benefits of Thru-Hull Transducers with High Performance Fairing Thru-hull installations provide best performance compared with other installation options for many reasons. • The best performance on vessels 25 feet and up because the transducer face is in “clean” water below the boundary layer (bubbles running down the hull) • The fairing compensates for hull deadrise and reduces turbulence over the transducer face, which allows tracking at speeds over 30 knots (35 MPH) • When mounted in clean water (forward of propellers and running gear), thru-hulls produce the most effective signal return since nothing on the vessel interferes with t

Why does frequency matter? High Frequency = Greater Detail (ex. 130-210 kHz) Selecting the best frequency for your specific application is very important. The good news is that once you know what frequency will work best for the type of fishing you do, there’s an AIRMAR transducer designed to maximize the performance of your sounder. • More sensitive to small targets and will send back detailed information which will display as crisp, high-resolution images on the echosounder screen • Best for shallower water and popular with anglers fishing at depths less than 1500 feet AIRMAR Chirp...

The Chirp Advantage Traditional sounders operate at only two discrete frequencies – typically 50 kHz and 200 kHz. This results in limited depth range, resolution, and ultimately what targets can be detected in the water column. In contrast, AIRMAR’s game-changing Chirp-ready transducers provide over 70+ kHz of bandwidth. Transmitting over a wide frequency band results in a greater o pportunity to detect what is in the water column. As a result, all targets detected in the entire bandwidth will be seen on the display–even those fish holding close to the bottom–ultimately improving target...
