I currently use the Triumph 2 as a base with the LS. For the last 5 years I have also had a Spectra Precision receiver paired with a Carlson data collector which was used with one of our local RTN systems. For certain jobs, it has been advantageous to use the Carlson data collector with SurvCE since I'm using Carlson office software. The Spectra Precision receiver has recently stopped working and I'd like to know what upgrades (and cost) if any are necessary so I can utilize the Triumph 2 as an RTN network rover with the Carlson data collector. It seems that the Triumph 2 is supported by Carlson SurvCE versions 4 and newer so hopefully that won't be an issue. I also want to make sure that whatever upgrades/changes are required would not interfere with the continued use of the Triumph 2 as the base for the LS.
