USING THE PRO CRAFT UNIT
MENU FUNCTIONS
The Zoom range is shown on the left side of the
screen and full range information is shown on the
right side of the display. Zoom can either operate
automatically, in which the Zoom range is constantly
adjusted to show the bottom, or manually, in which
the user controls the location of the Zoom range.
Automatic Zoom is especially helpful when looking
for structure or bottom detail. The Automatic
Zoom keeps the bottom in view even in quickly changing terrain, but is most
useful in flatter areas without considerable depth variation. Manual Zoom pro-
vides detailed information of any area from the surface to the bottom. In man-
ual Zoom, the Zoom range does not move as the terrain changes.
When the range is shown in the menu, the upper number represents the top of
the current Zoom range. The lower number represents the bottom of the Zoom
range. Use the UP and DOWN ARROW buttons to move this range. The upper
number can never be less than 0 (the surface of the water), and the lower num-
ber can never be greater than the active depth range. The difference between
the two numbers (the Zoom range) is preset and determined by the active depth
range.
Once manual Zoom is selected, the display appears the same as in Auto Zoom,
but the zoom range does not change automatically.
To disable Zoom, press the MENU button until the Zoom menu is on-screen. Use
the UP ARROW to highlight Off, and let the
menu time out.
When the unit is powered off, the Zoom
menu returns to Zoom Off.
Depth Alarm.
The Pro Craft unit contains
an audible alarm to warn you of shallow
water depths. The alarm is adjustable to
depths of 2' (.6m) to 99' (30m). When the
alarm is enabled, an audible alarm sounds if
the water beneath the boat is equal to or
less than the selected alarm depth. The
