I've just had a quick look at the Garmin Foretrex 301 GPS manual. Its pretty awful in that it is showing nothing I would consider useful. Yet the 301 is being marketed as useful for even military use.

I couldn't find any information on Datum settings and Compass Declination, WAAS etc, even my old Etrex Camo would even accept DGPS signals via the 232c cable for Differential GPS (using an external MBX-3S Differential Beacon Receiver) and would display OSGB 36 format for UK Ordnance Survey maps let alone MGRS, NAD27 etc (coordinate datum transformation) etc.

Connecting the Garmin eTrex GPS to another device using RTCM NMEA signals is also very useful to turn the GPS into a full electronic mapping system as well using a Notebook PC etc.

These basic eTrex's are fully featured (non electronic map display type) and cost effective.

Here is an example of a waypoint I recorded on my Samsung B2710 i.e. Ordnance Survey

and a video of the location where camp was setup

The location might be out by about 10-20 metres but technology today is pretty
