Very thorough! I looked to see if you mentioned whether the GPS had
a feature to prevent accidental power-up (on my old Magellan Meridian
gold I have to press 'enter' within a few secnds after hitting the
power button) but didn't see it mentioned. Something like this might
be useful to know, but if I missed where you wrote it let me know....
Just a few spelling errors ans a couple of minor things, and you're
good to upload. Going through your report, I wondered if you somehow
told spellcheck that "labelled" really was a word (I've managed to do
the same quite often when running spellcheck, and now my computer
probably is nearly as bad at spelling as I am!)
N.B. The IPX-7 standard is defined as "Protected against heavy seas
**edit: I think NB was supposed to be part of formatting?
Stated dimensions: 5.25" x 2.43" x 1.5" (13 cm x 6 cm x 4 cm)
**Comment: with the precision given to the hundredths for inches,
going to the tenths with the cm would probably be equivalent accuracy.
N.B. The measured weights are subject to the approximately .2 oz (6
g) tolerance of my scale.

Screen size, stated: 176 x 220 [pixels] daylight-readable TFT
[i.e. "thin film transistor liquid crystal display"]
Screen dimensions, measured: 1.7" x 1.4" (44 x 35 mm)
Comment: it might be best to stick with cm, since you use it for the
dimension of the whole unit.
As with most electronic devices, the DeLorme warranty is a bit more
limited than that for most outdoors gear. although in line with

The functions of the buttons are described here. There is, rather
surprisingly, no diagram of the front and back of the case, but as
the buttons on the unit are generally labelled or
otherwise fairly obvious, this may have been deemed unnecessary.
although if I were a beginning user, I might consider this a
shortcoming. A labeled
The GPS has a pre-programmed world highway base map (I'm using
DeLorme's designations for the various map types here). This is
hardwired into the unit, and provides only the most basic data. Shown
are major cities, coastal outlines, and main roads. For the US, only
Interstates are labelled
This means that when I'm stationary, examining the map, if I turn to
face a feature in the landscape, the pointer will not move, as my
change in orientation can't be calculated from the received GPS
satellite data. If I walk a short distance in the direction of the
This may if enabled in Setup) be reached
**edit: delete parentheses, or is it supposed to be (Setup)??
As with the Find page, this can be reached by "leafing through" using
the Page button, but is most quickly available via the Make Waypoint
button. A wide selection of waypoint symbols is available, and the
waypoint can be labelled
On the Panther Mountain excursion, the elevation at the summit was
read as 3712 ft (1131 m), taken using the waypoint averaging feature,
and this was an excellent match to the known highest contorur of 3720
I am very impressed by the PN-20's ability to pull in satellites in
just about any position. It seems that antenna technology must have
improved a lot recently, to judge by this! I did not have to to
resort to rotating the GPS in the direction of a

block reception, commonplace manoeuvres for most users of older GPS
