In this post on Choosing a GPSr (GPS receiver),we’d like to explain why or why not you may consider an alarm.
Some GPSr units can warn you when you’re approaching a waypoint. We can’t imagine why you’d want this for geocaching,because you’re presumably scrutinizing your destination anyway. What we’d really like to see is an alarm that reminds you to look up so you aren’t smacked in the head with a branch.
Do you use your GPSr’s alarm? Comment on this post to share!
