I am about to purchase a new GPS unit. I currently have a GeoXT and have used the combo of GPS Correct/ArcPad with GPS Analyst/ArcMap to correct the collected data to submeter (or close to it).
Looking at the GeoXH specs, it will already collect data at submeter. So if I use GPS Correct with a GeoXH, how much more accurate will it be? Will it just verify that my data has been collected at submeter accuracy or will it get corrected down to like subfoot accuracy or something?
I'm not familiar with technical details of GPS units, but was wondering if the upgrade to a GeoXH is worth the added cost?

We use the GeoXH with an external "Hurricane" antenna for sub-meter location using both Terrasync and Arcpad. With no canopy or obstructions and with longer fixes we have gotten close to foot level accuracy without a base station.
