The power save feature conserves battery power by changing the position
update rate. We recommend you test the power save feature in known
surroundings and determine its capabilities before venturing into unknown
territory. Experiment with modest settings, such as 1-second update (300ms) or
1 second update (200ms) and see if accuracy is adequate for you.
WARNING:
Full power settings will always give you the best, most accurate
performance with Atlas. Power save functions can extend battery life, but
aggressive power saving settings can reduce GPS accuracy, particularly in
demanding situations when signal availability is less than ideal. It is up to
you to decide if position accuracy or battery consumption is the most
important consideration for a particular navigation situation.
In potentially risky navigation situations, we suggest you consider the standard
operating procedure of professional cave explorers, who never enter an
undeveloped cave with fewer than
three
sources of light (a main light and
two
backups.) Even if you do carry a couple of spare sets of batteries, remember:
a
prudent navigator never depends on only one source of navigation information.
A good map and a Silva compass are important companions for you and your
Atlas.

There is another function that will help preserve battery life when practicing with
the unit indoors. Most of the time, the unit will not be able to find a satellite
