[MLB-WIRELESS] Choosing GPS

Hi,

I bought a Garmin eTrex (yellow) in the US and have used it a bit here
mostly walking.  We compared the altimeter to a pressure based one we
were carrying, both were accurate enough to find our position amongst
contours (although we lost GPS in the woods at times).

I really like it, seems to meet your requirements (buy a 3rd party
serial cable on ebay or online).  I have the cable, but I've never used
it.

The yellow eTrex does not have the inbuilt magnetic sensor.  I am told
that these really kill batteries and thus are not so useful (you can
turn them off to conserve power).

Unless you want mapping, this unit is probably enough.

Cheers,
Tom
