DualBeam Sonar

Your 500 Series™ Fishfinder uses a 200/83 kHz DualBeam sonar system with a wide (60°) area of coverage. DualBeam sonar is optimized to show the greatest bottom definition using a narrow (20°) beam yet can still indicate fish found in the wide (60°) beam when the Fish ID+™ feature is turned on. DualBeam is ideal for a wide range of conditions - from shallow to very deep water in both fresh and salt water. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions, and transducer installation.
