JR said:I have a budget of around £150.00 - £175.00 and looking for a 1/2
decent GPS system.
Many devices around in the budget from Garmin and Magellan (and others)
which do most of the things on your list.
Your budget won't stretch to a decent mapping display, but also, unless you
get into DIY mapping or public domain hacks(*), there aren't maps to load
into hand-held GPS units which are useful for walking in Europe (except one
software product for Magellan which seemed inadequate when I looked at it).
Beware cheap imports of mapping GPS units, the basemap might not be the
European one and that might be a limitation for your use (so do some
research before chasing an Ebay bargain to decide if it really is a bargain
! I think the differences in non-mapping units is considerably less.)
Cheapest option would probably be a Garmin Geko 201 (the 101 doesn't connect
to a computer) or Etrex (the yellow model). If going for the base Etrex
check that its software version is 3.0 or higher, this means it has the
improved internals which give more waypoints, tracks, and better battery
life.
Altimeter & compass requirement reduces your options a bit; the Etrex Geko
301 is probably the best price option; its battery consumption is
considerably better than the old Etrex Vista, and the newer Etrex
Vista-Color (excellent device with superb screen, mapping and good battery
life) is double your budget. The Garmin altimeter is very good,
particularly its ability to self-correct against GPS data. Electronic
magnetic compass on Garmin units eats batteries, though can be turned on and
off fairly quickly. Leave it off most of the time and rely on the GPS
compass.
Include in your budget the lead to connect to computer, battery charger and
a few sets of rechargable NiMH batteries. This can easily be £50.
If purchasing a mapping unit, work out where your maps will come from in
advance; commercial hand-held GPS mapping is roads-only for Europe and quite
expensive.
USB isn't necessary for waypoint, route and track history access, serial
would be adequate.
However, USB makes a huge difference if you go up the price to a mapping
units; my Vista-C (USB) takes no more than 90seconds to load its entire
memory with a new set of maps, whereas a friends old Vista model takes 20-30
minutes over a serial lead.
(* whereas if you do get into DIY maps, you can get contour data for all of
Europe which is fairly accurate and does make a mapping unit quite useful).
