[time-nuts] GPS question

[Joseph Gray]

Am I correct in assuming that the position given by a WAAS enabled handheld 
GPS unit is more accurate than the position reported by my Z3801? 
Specifically, I tried a Garmin eTrex Legend Cx with WAAS enabled and used 
averaging mode for the waypoint.

On a related question, the eTrex reported that the position was +- 6ft. Is 
that really 6ft, or is that 6ft in addition to the 3M claimed accuracy of 
WAAS?

Thanks.
