The iPhone Geocaching app that was developed by Groundspeak is an excellent app. A lot of new geocachers seem to be coming involved with the sport through this app. While groundspeak continue to refine and update the app there is one fatal flaw. That is the accuracy of the GPSr chipset as used by the iPhone.
I used the iPhone app to locate my first 50 finds before buying a GPS. My tip to the new geocacher are:
- If you are having problem as a cache always check the location of the cache with the Google Maps App. This will give you a better idea of where the cache is located. It will also show you your current location which you will see may be wrong because of the inaccuracy of the GPSr.
- Never set a hide location using only the iPhone coords. Check them against Google Earth to confirm them before posting the location. There have been a couple of new cachers caught out recently. The coords can be out by up to 1000m.
