Using the Marine Timer
The Marine Timer, specifically designed for sail boat racing, allows
you to easily count up or down by specified time increments. As
is common in sail boat racing, there is often a 5-minute warning
countdown, followed by a 4-minute preparation countdown, and
finally a 1-minute final countdown.
You can use your GPSMAP 580/585 to perform each of these
different countdowns.
To open the Marine Timer:
1. On the Compass page, press Menu.
2. Highlight Set Up Page Layout, and press Enter.
3. Highlight 2 Columns With Timer, and press Enter. The
Marine Timer appears in the lower right corner.
