We know that specific frequencies excel at detecting certain fish species: bluefin tuna (60 kHz), squid (133 kHz), and cod (175 kHz). The Airmar TM265LH transducer includes all of these frequencies, plus all other frequencies within the high and low bandwidth ranges. This capability delivers excellent resolution, bottom discrimination, and bait-to-game fish separation at all depths. The Airmar TM265LH is equipped with a seven-element low-frequency array operating between 42 and 65 kHz for outstanding deep-water performance. The high-frequency ceramic operates between 130 and 210 kHz with a narrow 10° to 6° beam, making it ideal for separating structure and identifying fish tightly holding to structure.
