Single Beam Sonar

Your Humminbird® 515, 525 or 535 Fishfinder uses a 200 kHz single beam sonar system with a 20° area of coverage. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation.

DualBeam Sonar

(565 Fishfinders only)

Your Humminbird® Fishfinder 565 uses a 200/83 kHz Dual Beam 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.

NOTE: It's important to note that your 565 Fishfinder is a DualBeam-only unit and should not be confused with the DualBeam PLUS™ functionality of the 575 Fishfinder. DualBeam will only show hollow fish symbols from the wide 83 kHz beam when Fish ID+™ is turned on. You cannot view the 83k Hz sonar information separately from the 200 kHz sonar information as you can in a DualBeam Plus™ 575 Fishfinder unit.
