Summary: Could not figure out how to get this product to work. I tried garmin.com's site, I tried the iPhone app. Ended up waiting my money and time for something that either does not work or is too hard to get working. Oh well. Neat idea. Fail.
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. I found the cache and logged my entry. Between the GPS and the chirp you can be a more successful Geocacher.
Summary: I purchased and then immediately returned it by the grace of Amazon because I guess that it's not normally accepted as a return - SO CHECK THE RETURN POLICY BEFORE YOU PURCHASE BECAUSE AMAZON MADE AN EXCEPTION FOR ME and accepted my return but they said that it's not usually accepted once you purchase it. I purchased the product because, stupid me, I expected it to work with my Nuvi GPS system, which it does not do.
Summary: We are finding these add a new and exciting element to the world of geocaching and intend to buy several more. So far, we are very pleased and are really having a lot of fun figuring out how we can add them to more and more geocaches.
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.
Summary: The chirp works as advertised, except that under typical conditions its range is shorter that specified. The "chirp" sound would be more effective, if the Garmin GPS devices had a louder audio alert beep.
