POCKET/KEEL MOUNT Pocket/Keel Chirp Transducers Unlock the true potential of your fishfinder with the superior quality and performance of an AIRMAR Chirp-ready transducer. PM411LWM screenshot courtesy of Garmin The Benefits of AIRMAR’s Chirp-ready Transducers Benefits of Pocket Mount Transducers • One broadband transducer covers up to 117 kHz of A popular choice for boat builders, pocket mount transducers are installed within a small custom pocket in your vessel’s hull or keel, flush to the surface. Though retrofit installation is possible, these transducers are most commonly used in vessels with a suitable pre-cut pocket. 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. Advantages: • All the benefits of a thru-hull without the need for a high-performance fairing • Can accommodate any deadrise angle based on pocket construction • Can be used with all propulsion types • Reliable, accurate sonar performance with less

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...
