Summary: I bought this beacon End of 2010 and used it in an geocache for 3 3/4 years before the original battery died! After replacement I put it back and the battery just died again. I think if you're looking for a beacon this is it. At least when you've a Garmin GPSr :D
Summary: Works completely as advertised. I am glad I purchased this when I did. I have noticed an increase in cost every where these are sold. Works great and easy to install the battery. In fact, allow me to suggest that you wait until you are ready to place this in the field before installing the battery...
Summary: I am just getting into Geocaching and stumbled on the "Chirp" via Garmin's web site and my Montana 650T device. When I set the Chirp up and went to my first cache, it made a "chirp" sound on my GPS a half mile prior to the cache site to alert me I was getting close.
Summary: This little unit met and surpassed my expectations. It works as advertised. I'm using it in a multi stage geocache setup. As people get close to the beacon, it transmits the location data and hint or note to a respective GPSr unit. Great fun!
Summary: Works great with the Garmin GPSMAP 62! Not only for geocaching! Use this Garmin Chip to mark interesting places on the trail or your favorite camp spot. Battery lasts forever but its always a good idea to keep a spare 2032 battery in your camp or hiking sack for the chirp.
Summary: I love the chirp. I placed my first one the other week and it seems to be a hit. Easy to program, waterproof, small and easy to hide. I could hit it from 10 meters away without a problem. I never read the instructions until I had finished with it. I will be buying a few more of these.
