Top part, long battery life

I use this, we call it gadget geocaching and biking in the area. With moderate use, it holds now been exactly 647 days with a battery!
Interesting to see how the temperatures behave when it rains while biking or you can take in valleys or deep woods!
Would buy again!

Those who have mounting problems. Just take a cable tie and pulls it through the bracket when stationary mounted, for example on the bicycle. I've attached it to the GPS wrist strap on Garmin. In the 2 years it is not even abegegangen! When Geocaching not, nor in bumpy downhill rides! I am even so dangling run in his hand, holding clip!
