Dual Search & Dual Frequency
The FishEasy 250 DS is packed with a Dual Search Skimmer Trans- ducer that can transmit at 83 kHz and 200 kHz. The SeaFinder 250 DF has a dual frequency transducer that transmits at 50kHz and 200kHz.
A new innovation, the 83 kHz frequency offers superior sonar perform- ance at all depths from very shallow up to 1,000 ft and provides up to 120º of fishfinding coverage.
