Today’s top billfish-tournament captains are calling Airmar’s R409LWM 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.
