Using the Marine Timer
The Marine Timer, specically designed for sail boat racing, allows
you to easily count up or down by specied 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
nally a 1-minute nal countdown. Then during the race, mariners
might want to count up to keep track of their time.
You can use your GPSMAP 378/478 to perform each of these
different countdowns.
To open the Marine Timer:
1. Press MENU on the Compass Page.
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.
