This is a good question on one level. Although there are limitations to anybodys' GPS's accuracy based on foliage, clouds, rain, etc., different model's chipsets are more accurate than others in places like the woods and urban canyons. May as well seek out the most accurate GPS, yes?
For instance, I have a Garmin eTrex legend, which uses a different chipset than the garmin 60Csx. I have heard people say that the chipset on the 60Cxs is so good that you can get a position fix indoors. My eTrex does not. I would imagine that under a tree canopy, the 60Csx will outperform the Legend.
I may be wrong, but the Garmin 60Csx uses the SiRF Star III chipset, yes? The Legend has a previous generation chipset.
Supposedly the DeLorme chipset is better than the SiRF Star III, but I have nothing to verify this other than a post from DeLorme somewhere in this forum. Apparently, they're having issues with WAIS reception, which also affects accuracy.
When looking for a GPS for The Pig, I had been looking at the DeLorme PN-40 and the Garmin 60Csx, so I had essentially the same question.
Then again, I'm a noobie too, so take this with a grain of salt...
