Side imaging: 420KHz to 520KHz
DualBeam Plus: 175kHz to 225kHz and 75kHz to 95kHz
Down-imaging: 420kHz to 520kHz
The side imaging fish finder sonar can emit about a 240-foot beam on either side, and it helps to cover a large percentage of the water the surrounds the boat. Another lovely thing about the Helix 7 CHIRP SI transducer is that it is fitted with a thermometer measuring the water temperature. It comes with a transom mount and 6m cable.

Max Mode displays terrain information, fish representations, and water currents.
