We can see the 60CSX is very steadily drifting around. It travelled over a mile while at my desk. If I view the map screen on the unit and am sufficiently zoomed in, it's pretty black.
The 60CS, since it had no lock, tended to rack up distance quickly in the bursts when it did have a lock as it didn't have opportunity to average for very long and had a poor fix when it had anything at all.
The Explorist readings quickly stablized and levelled off as the positional averaging in that unit kicked in. |
