It is my understanding that the software in WAAS enabled receivers do
not check constantly - that is my understanding.

Curiously enough, I have a Magellon 315 and 330M and the 315 is a tad
more accurate (will show zero error for instance) than the 330 (I
never get zero error) which is WAAS enabled.

When I first noticed that, I thought that the WAAS receiver would be
more accurate.

Aboard Lionheart, leaving the Raymarine Raystar 120 Seatalk WAAS-GPS
and its RL70CRC Plus radar display/chartplotter on for long periods of
time tied to E-dock, I plot the Raystar 120's position centered around
its position on the hard top varying from about 30' off the stern to
near the bow to about halfway across the boats next door to port and
starboard, easily within the 3 meter accuracy circle that's specified.
The boat's in Charleston, SC, so has good WAAS view at about 45
degrees elevation.

It's not quite good enough for ILS approach, but damned close!

Clicking the waypoints on top of a bouy symbol is NOT a good idea....
