So far in this thread I have been pro Delorme, but the PNs do have some drawbacks.
First, the PN-20 and PN-40 eat batteries like crazy. The -60 is supposed to be better, but I don’t know how much. And… they will even drain the batteries when turned off.
The learning curve is a little steep, but after a short time, you will be able to use the most common features without even looking at the unit.
The screen is easy to read in any light, including bright sunlight, but it’s too darn small…
I haven’t figured out if this is a pro or a con, but the default proximity beeps (nearing turn, turn now, nearing cache) are different than the Garmins, so they really bug the heck out of zuma. They can be changed to sound more Garmin-like.
