job. Battery life is good (full day with rechargeable batteries at 1 sec
sampling). Resolution is good (down to 1 meter with good satellite
visibility), especially with the newer model. Position reproducibility is
also good (down to 2 meters with the etrex 20). They work for hours under
pouring rain. Apart from the well-known user-unfriendlyness of Garmin
products, the only fly in the ointment is that the newer unit occasionally
produces corrupt files - they are still perfect ASCII files, but the syntax
is not correct. Normally such files are easily repairable by hand - not
sure if it's a dodgy unit or a general problem.
OSM maps in the US are of different levels of quality. When I last mapped
on the CA west coast (Big Sur, where else?) I noted loads of non-existing
roads still there from the old Tiger import.
