The new Zercom LPG (Liquid Paper Graph) is a state-of-the-art, high-resolution fishfinder that provides highly detailed sonar images on a 320-by-240-pixel LCD screen. This dual-beam sonar yields excellent bottom detail and records fish targets as arches, just like the old paper-chart recorders used to! The LPG features simple rotary controls with all functions accessed through four knobs. One knob selects the operation mode, and a large rotary gain-control knob adjusts sensitivity. The LPG operates at 250 kHz, so it can be used simultaneously with other fishfinders. Additional features include a split-screen Real Time Sonar display, digital depth display, a shallow-water alarm, and speed and temperature indicators. The unit is completely waterproof and includes a high-speed transom transducer. Techsonic Industries, Eufala, AL; (800) 747-9329; www.zercom.com.
