I'm no apologist for any company and am aware of canopy in acquiring signals. In my province canopy is not a problem during hunting season and rarely during fishing. Going in, taking a shot at lake- or road-side provides lots of sky. Just punch that waypoint when you're coming out. Fifty-foot or less accuracy from my inexpensive etrex Venture has been backing up my dead-reckoning for the last five years. Its repeatability to a waypoint has been as close as three to five metres.

Fifteen years ago, my son, chief pilot for McCain's, bought a $1,500 Garmin for the hell of it and attached an antenna with suction cup to a Falcon 50's side-window. The expensive inertial navigation systems were all over the place during oceanic travel. Approaching, Europe he asked Shannon for a report on the Garmin's positioning through the "gate." Dead-centre.
