Custom screen 1

Custom screen 2

Low and high frequency echosounder display can be set up sepa-

rately. The low frequency display will show deep water bottom

contours, and the high frequency display will show the mid-water

section with trawl targets or bait fish in a higher resolution.

The Dual frequency display will provide both the 50kHz and the

200kHz echo displays in one screen.

The two custom screens will present multiple window combinations

(section 4.2), where one of the main echo displays i.e. 50kHz or

200kHz will be fixed in the left half of the screen. Adjustments can

be made individually to both displays (section 4.7).

function displays with a new display. Refer to section 2.1, 2.1.1 and
