Calibrated scale
This scale gives the user an intuitive image of the depth
of water and the depth to the shoal of fish. The user can
choose to enlarge a specific depth area to get a better look
at interesting shoals.
Upper zoom limit
Gives the value for the shown upper limit. The value
depends on the depth area and the zoom value. If local
zoom is disabled the upper zoom limit is 0. For other zoom
values the upper zoom limit corresponds to the difference
between the bottom zoom limit and the zoom value. If the
value for the lower zoom limit is less than the zoom value
the value for the upper zoom limit is 0.
