Summary: This unit worked really well for the first 4 uses, then it froze up and wouldn't restart. Upon further review, it turns out that Delorme has a bad capacitor setup in the device, which innumerable people have had similar problems with.
Summary: I purchased my PN-40 3 years ago and have found it consistently unreliable. It locks up unexpectedly, burns through batteries rapidly when it does work, and the screen blinks when I try to sync it to my computer.
Summary: I've been using my Blackberry Smartphone with the Trimble app for Geocaching. Being new to geocaching and to GPS', I found the combination to work quite well. The app costs about $6/month. I thought I'd try something more sophisticated to see if it was "better" than my Smartphone.
Summary: Delorme needs to stick with what they do best (maps), fire their software designers and partner with someone who can make a more functional GPS! After considerable research, I purchased my first GPS, a PN-20, primarily because of Delorme's reputation for great maps.
Summary: I'm a geocacher and thought that this gps would aid in my hobby. The PN40 was useless. It eats batteries like they're going out of style, and when it lost the signal it would take as much as 40 minutes to get it back.
Summary: I purchased the Delorme PN 40. It did not work. It was frozen on the first screen. Followed the fix it screens on the website and they did not work. Contacted DeLorme. Not user friendly. had to go thru a series of drills just to get authorization to ship it back. Have yet to use.
Summary: This is an over priced GPS. I called the company DeLorme and spoke with a technician and was told by him that lat/Lon positions could be imputed to go to that position. False. Download of maps is not only a challenge, but when done by the numbers there are errors which cause the maps not to be...
Summary: I paid promptly and the unit took over two weeks to get to me. When testing the unit it ran through 6 sets of batteries!!! Hard to believe you didn't notice that? I sent it off to DeLorme and they fixed it was a hassle that should of been handled by original purchaser.
Summary: I started out geocaching with an original Garmin 60 GPS. That was a very good unit but I wanted something that I could download caches easier with along with descriptions. I was going to upgrade to the Garmin 60CSx but with the recommendation of a friend I purched the Delorme PN-40.
