Summary: As a technical and computer savvy individual I expected to be able to overcome the poor user manual and complicated non-intuitive interface for loading data and maps. Was I wrong! Something as simple as paying for and downloading a USGS quad segment proved impossible. Tried with both PN-40 connected to computer and not. I can pay for and receive download to my hard drive, but downloaded file cannot be transferred to PN-40 or SD card.
Summary: alright let's review this thing. the pn-40 from Delorme is one bad mammajamma. but not in a "why did i spend that wad of cash" kind of way, more of a "i can't believe i can do this" kind of way. let me preface this review by saying that my main use of this device is geocaching. (though its orange case makes it incredibly more difficult to act as though i'm talking on my phone than staring at a map when there are Muggles--non geocache folk--around).
Summary: I purchased this product for my husband's birthday, as we both want to get into geocaching. Now, understand, I am not a stupid person, nor am I totally technologically challenged. I am the average buyer who owns a vehicle GPS unit and wanted to move on to the world of geocaching. I read reviews around the Internet before making the decision to buy this particular model and manufacturer.. but there's one thing all those great reviews have left off.
Summary: I used to own the Garmin Vista until it was stolen out of my car, so I have been looking for a new better GPS that is not so restrictive with maps and software like Garmin. AS I read reviews DeLorme was raved about due to its software, even tho it is really hard to learn how to actually use it. So I took the unit hiking and having already read the reviews about how bad this thing is with batteries I took 4 fresh Energizer batteries.
Summary: I must say that I find it interesting that there are so many glowing reviews about this flawless GPS. I am always skeptical of anything that sounds too good! I read many of the reviews online, and after evaluating the specifications and features, opted to buy the Delorme PN-40. Prior to this purchase, I owned a Garmin 60CSX GPS. I believed that the Delorme was poised to be a significant improvement in both the tracking ability and the display of aerial overlays.
Summary: This is a great GPS with many cool features, but it is definitely not intended for marine use with the advertised NOAA marine charts. You'll have to use the included cumbersome software to load NOAA charts at $10 per charts or unlimited with the subscription. The charts are basically scanned NOAA maps turned into bitmaps at very low resolution that get uploaded into the GPS and overlay on top of the maps. The resolution used is way lower than the original charts.
