Constantly adjusting transmitter and receiver parameters, the DSM300 with HDFI technology intelligently analyzes fish and bottom echoes and automatically produces a crystal clear echo sounder display. An amazing technology breakthrough, HDFI echo sounders from Raymarine deliver exceptional clarity and detail that cannot be matched by conventional fishfinders.
