Re: GPS units: need info.

["Duncan Fletcher" <dfletche@gte.net>]

There are 2 types of storage. They will store track points automatically. My
Garmin 12 will store 1024 of these. You can adjust how often these are
generated. Waypoints must be entered manually by pushing a button (and
another to confirm): the Garmin 12 holds 300. The numbers of other units
will vary.

But the automatic use can lead to not being aware that the unit has lost
satellite contact and is either giving you a track point based on only 2
satelites with substantially reduced accuracy or no reading at all.

Even with good view of the sky, there is an error range of several hundred
feet due to the miltary fudge factor.
