Zoom Pan

Your unit has the handy ability to quickly zoom in on any portion of the
water column with just the touch of an arrow key. The Zoom Pan feature
lets you rapidly move the zoomed area up and down to different depths.
By "pointing" your zoom at different portions of the chart as it scrolls,
you can get a good, close-up look at structure or cover below you.
To use Zoom Pan, switch to a manual depth Range setting (see page 23)
and turn on 2X or 4X Zoom. Then, simply press ↑ or ↓ to pan up and
down the water column.
