Not sure how many of you are familiar with Geocaching but I started using my PB for the GPS and it's BB Bridge functionality to log my reports on Geocaching - The Official Global GPS Cache Hunt Site.
I download the free trial of CacheSense and went searching. I was very impressed with this app and the PB. The compass and radar worked well and when I found the cache I was able to log on the website within the app. If this experience continues throughout the trial I am definitely buying this app.
