Power Saving
iFINDER contains a battery capacity indicator, and will also flash low battery warning messages when battery power declines to a certain level. When plugged into the DC cigarette lighter adapter, the power indicator displays the "External Power" message. This message some- times appears for a few minutes when using fresh batteries.

The power save feature conserves battery power by changing the posi- tion 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 (300 ms) or 1 second update (200 ms) and see if accuracy is adequate for you.
WARNING:
Full power settings will always give you the best, most accurate performance with iFINDER. Power save functions can extend bat- tery life, but aggressive power saving settings can reduce GPS ac- curacy, particularly in demanding situations when signal availabil- ity is less than ideal. It is up to you to decide if position accuracy or battery consumption is the most important consideration for a par- ticular 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
