See the following list of products, all of which are covered by this manual, to find your HELIX Series model: • HELIX SONAR: Wide screen Fishfinder with DualBeam PLUS sonar. • When all the echoes are viewed side by side, an easy to interpret “graph” of the bottom, fish, and structure appears. The sound pulses are transmitted at various frequencies depending on the application. Very high frequencies (455 kHz) are used for greatest definition but the operating depth is limited. • DualBeam PLUS Sonar (HELIX SONAR) The HELIX SONAR Fishfinder uses a 200/83 kHz DualBeam PLUS sonar system with a wide (60°) area 20˚ of coverage.
