BEAM
Beam allows you to switch the frequency of your sonar beam. The Beam
function allows you to eliminate cross-talk interference from neighboring
fishfinders or to simply choose the type of beam that suits your fishing needs.
Selecting 240 kHz will provide a wider beam with more coverage but less detail, while
selecting 455 kHz will provide a narrower beam with more resolution.
NOTE: Your other option is to use the Noise key to reduce cross-talk interference (see
Noise Rejection for more information).
1. Press the Beam key to toggle between 240 kHz and 455 kHz.
