When you open the echosounder settings, the first option you will see is the "Hyper" toggle button. This allows you to turn on the Hypervision mode in the Downscan echosounder view. This function can only be used when the Downscan view is active, whether in single view, sidescan or in the 50/50 view.

The differences between having Hypervision activated and deactivated will be further explained in the Downscan section.
