We know that specific frequencies excel at detecting certain species of fish: 
Bluefin Tuna—60 kHz, squid—133 kHz, and cod—175 kHz. The B265LH transducer 
includes all these frequencies plus every other frequency in the high and low 
bandwidths. This powerhouse delivers excellent resolution, bottom 
discrimination, and bait and game-fish separation at all depths.
Airmar’s B265LH is packed with a seven-element, low-frequency array that 
operates between 42 and 65 kHz for excellent deep-water performance. The 
high-frequency ceramic operates between 130 and 210 kHz with a narrow, 10° to 
6°, beam—perfect for picking apart structure and pinpointing tight-holding fish 
in structure.
The included High-performance Fairing improves broadband performance at speeds 
over 30 knots (34 MPH).
