There is a lot of stuff but getting out of date fast, so some help on
newer (as in still available) models would be appreciated.
I've checked
http://www.globalpositioningsystems.co.uk
and Garmin site
but not too clear on the functionality I need.
I want to enter preplanned walks using a many as 50 OS 2-letter and
3(or6) easting/northing per walk.
Must be able to store multiple walks.
Want to have a route shown so I can see how far between points I am
and get a rough idea as to how far to the next point (waymark ?).
Allow alternative routes per walk (ideally)
Good battery life 10 hours minimum so I can use one set at most per
day.
Compass (when I move is OK - but I've seen some reviews that suggest
that some devices don't have compasses although never seen a device
that doesn't)
Connecting to a PC so that I can use a keyboard for the grid
references and download easily (USB preferred).
Distance/average speed travelled.
Distance of planned walk (I know this won't be accurate as it will
have to be in straight lines and ignore height etc.) but it will be a
guide if I put enough points in.
AND
backtrack in case I get lost !
I'd like to go for a fancy system with maps and all but it looks like
these cost money to get the maps on and I really want OS maps with
contours etc. so looks like a basic GPS is more what I am after.
Last of all - cheap ! Will the 201 do the job (for £107) or is there
something that is missing. I might have forgotten something that a 201
owner would say...if only I had thought of .... ???
Many thanks
