Summary: There are a lot of "Cool Aid" drinkers for the Delorme products. Probably because if you somehow figure out their mapping software after hrs and hrs you dont want to admit you probably made the wrong choice. My PN40 never has worked properly, doesnt turn on, doesnt turn off, stays on for 5 mins- batteries die, freezes, compass constantly needs re-calibrating, etc. etc. If you research carefully you will find these issues are common. This is supposed to be a GPS!
Summary: The Pro's - maps are excellent. The con's - battery thirsty and prone to lock-up. I attempted to work through Delorme customer service to remedy the lock-up / clear the memory without success. I followed up by sending the unit to Delorme for repair - they offered to repair the unit for $100 - which sounds reasonable - but this unit has already been sent in during its warranty period and had the boards replaced during that occasion for the same reason.
Summary: First the pros. The unit is bigger than the Garmin Etrex units. For me this is a good point since I have biggish hands and prefer a unit large enough to handle comfortably (the Garmin 76 line are what I consider a reasonable size). The accuracy and initial position fix times are excellent. Cons: . Battery life is pathetic, . Downloaded data files are problematic with other software.
Summary: This GPS has been nothing but problems. It always had problems turning on. It will not charge, and finally gave up switching on at all. Amazon will not take it back (used only 4 hours and less than 5 months). They have a 30 day return policy. STRONGLY suggest looking at another unit and purchasing at REI.
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. Reviews for the PN-40 were pretty good so I bought one. It's certainly not for the beginner. I'm a retired EE and am quite computer literate. The instruction manual is poorly written.
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. The PN-20's graphics were terribly slow, so I returned it and made the mistake of buying the newly-released PN-40.
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. I was in a deep search when the gps froze, thank goodness I had my 98 cent compass to get me back.
Good when you first buy, but beware of issues later

Summary: Purchased this unit in December of 2008 through Amazon. The units buttons wore immediately. After about six month of intermittant usage, the system started to reset and occasionally lose geocaching data. Found resolve on message boards, but issue continued. After about 17-18 months of usage, base map would not show after zooming out to 4 miles. Had to hard boot and reinstall software. Beware of the claim that the unit is waterproof, it is not.
