I guess that still seems a little optimistic to me for emergency purposes. I can understand
@Whiskey_Fish 's perspective where he keeps it on but doesn't send a track (relying on a missed check-in and the subsequent ping to locate him - please make sure you have that option for users to locate you turned on in Mapshare!), as it might save battery life and might be cheaper. However, turning it off unless you're in trouble seems silly.
Even when I hunt with a buddy, there are still times when we split up to attack an objective or scout an area. We always have a meeting point set up, and generally it's not far. But folks do get turned around (or "I just thought I saw something go over the ridge so I wanted to peek over", etc) and even if they are within a 1/2 mile, that can still be almost impossible to find it tough terrain (especially with a fall). To each their own, of course, but that almost nullifies the of the reasons I got the inReach in the first place.
