The Airmar M265LH covers 103 kHz of total bandwidth from a single in-hull transducer, targeting the precise frequencies that matter most — 60 kHz for bluefin tuna, 133 kHz for squid, 175 kHz for cod — along with everything else within its low and high bands. A seven-element low-frequency array operates from 42 to 65 kHz for deep-water reach, while the high-frequency ceramic element spans 130 to 210 kHz with a tight 10° to 6° beamwidth for precise structure and fish separation. Installation uses the included mounting tank, which is trimmed to the hull's deadrise angle and bonded inside the hull — no through-hull drilling required, making it well-suited for trailered or lifted vessels. A Mix & Match Cable is required and sold separately.
