PM411LWM Ultra-wide Chirp-ready Pocket/Keel Mount
Part NumberPM411LWM
2 kW
Today’s top billfish-tournament captains are calling Airmar’s PM411LWM their “go to” transducer for seeking out targets and pinpointing them in deep water. This ultra-wide transducer features a 40° beamwidth for an amazing amount of fish-finding coverage under the boat. Coupling the low-frequency range of 40 to 60 kHz with the medium range of 80 to 130 kHz, this tournament-series transducer reveals more fish in the water column than ever before.
Captains are pairing this transducer with a PM275LHW or a B175HW for a combined package covering low to high frequencies with both wide and narrow beams.
The PM411LWM is one of our Universal Pocket Mount transducers, engineered to fit the same compact pocket footprint—with identical length, width, height, mounting bolt pattern and size, and faceplate. All models feature bare-wire terminations and can be used with electronics from any brand.
For boatbuilders and installers, this means you can standardize your hull cutouts while offering customers a seamless range of compatible options from 1 kW to 3 kW. One standardized footprint. More options. Greater flexibility.
