Camas, WA — Furuno is proud to introduce the new CH-300 Dual-Frequency Searchlight Sonar, the world’s first dual-frequency sonar! This sonar is built specifically for sport fishing battlewagons and commercial fishing vessels that are looking for an extra edge. With traditional sonars, you pick either a low frequency or high frequency version, but with the CH300 it’s like getting two sonars in one.

This revolutionary, dual-frequency sonar has the advantage of both high and low frequencies in one unit to search on a rough seabed and to greatly enhance fish school detection. Its operating frequency can be selected from either 60/153kHz or 85/215kHz. The lower frequencies enable long-range searches of over 1,600 feet. The higher frequencies, give a highly detailed search near and around the vessel.

This week Simrad released a major software upgrade for the popular Simrad SH80 high resolution, high frequency fishery sonar.

The software upgrade includes a brand new noise filter. This will remove impulsive noise like cavitating propellers and interference from other sonars and echo sounders on nearby vessels.
