We know that specific frequencies excel at detecting certain species of fish: Bluefin Tuna 60 kHz, Squid 133 kHz and Cod 175 kHz. The PM265LH transducer includes all these frequencies plus every other frequency in the high and low bandwidth. This powerhouse transducer delivers excellent resolution, bottom discrimination and bait and game fish separation at all depths. The PM265LH is packed with a seven-element, low frequency array that operates between 42 kHz and 65 kHz for excellent deep water performance. The high frequency ceramic operates between 130 kHz and 210 kHz with a narrow (10 deg to 6 deg), perfect for pick apart structure and pinpointing tight holding fish in structure.
