Anyone have any real world experience with comparing the two units side by side as far as accurancy? Can you really get that much closer to your target?

My Garmin GPS-12 and GPS-12XL's are as accurate as any WAAS GPS that I ever compared them to. They put me right on top of my spots 100% of the time.
I am very interested in this too - could this be because the WAAS units
are not always able to pick up the required extra signals, and you are
essentially "non WAAS"? Wish I knew more about it, my differential receiver
has a screen you can go to and see how good your reception is, whether it
is working or not. Do WAAS units have this? I have heard some folks say
that the WAAS signal did not seem to work on theirs around here, is it
global coverage, or just in spots like Loran used to be? I guess I'm gonna
have to spend an entire evening searching the web to answer some of this...
Actually a a gogle search on WASS immediately brings up some very informataive information. It looks like it all boils down as to where you are. My boys got me one of Lowrance's iFinder H2O with an active external antenna. It seems to make a lot of difference on the strength and number of satelites acquired. Now I've go to figure out whta all that means. I've also got the Map Create 6 USA Topo version. Sure is a lot of info in that thing.Quote:

howdy; thanks for the websites. am majoring in gis/gps technology and they are just what i have been looking for to help understand some of what the teacher is talking about. sometimes it takes another point of view for something to penetrate this thick skull. again many thanks for the sites. tarfu
