Thanks Lance, do you sell any of these products or are you mostly involved with the add-on  RTK type stuff? sounds like the 372 would open up my options considerably, which is probably the option I'll go with. 

I have a Raven Phoenix 300 and also the earlier version that is Omni unlocked and a Raven MBA 6 antenna, are those compatible with a Pro 700, and with some of the "things" you have available work to make it work on RTK ?

Feel free to contact me at 319 nine36 sixty364 or [email protected]
