Use WAAS/EGNOS
The iFINDER ExpeditionC has a new feature that allows users to turn
WAAS and EGNOS reception on and off. The default value is on. EG-
NOS (European Geostationary Navigation Overlay Service) is the
European equivalent of WAAS. Like WAAS, it makes GPS position cal-
culation more accurate. To determine the accuracy in your area, place
yourself in a known location and turn on the GPS. Note your location
on the map with WAAS/EGNOS on, then turn it off and check again.
Use the setting most accurate in your area.
