Range Menu
The Range menu is where you can pre-set
basic ranges, zoom range, bottom lock range,
and turn independent range adjustment on or
off. The default values are suitable for most
fishing applications, however you may wish to
change pre-set ranges to suit your needs.
Note that when the depth unit is changed all
range settings are restored to default. There-
fore, it is a good idea to change the depth unit
first and then change ranges.
