I've only always used Topcon GPS and Total stations running Carlson SurvCE and am interested in a used, older but still reliable robotic total station. In particular, the models that can also be set up as a Smartstation. I'm not really sure which ones are capable, but I'm looking at TCRP 1203/1205, 1203+/1205+ models. What is the difference between the plus and non-plus models? Also, can the older 1103/1105 models be set up as a Smartstation. And what are the differences between say R100, R400, and R1000's?
Please forgive my ignorance, as Leica is completely foreign to me.
Please weigh in with anything and everything.
