Thanks for the manual, it's a big help. I don't have a data collector at the moment, I just bought this for personal use, I am fairly new to them. What is the most cost effective way to go regarding data collectors for these?

Also I seem to be having issues with the EDM. I don't have a prism as of yet so this may be causing the issues I am encountering. Is there a way to test without one? It does turn on, I can hear a click and see a red light in the scope.

Topcon Gts-236n User Manual

It comes up with - C in the display which according to the manual means poor light. I am not getting any error messages which hopefully is a good sign and it is just operator error. I have only used regular electronic theodolites in the past, so these total stations are new to me. Any help would be good. There is a great variation in how well bicycle/traffic safety reflectors work. I find that the approx 1 inch ones distributed in the US are useless because their scatter pattern is too broad and has holes in it. Some brands of the 3' ones are good.

The Hillman brand red 3' is better. The Hillman reflective tape strips are not as good as the circular reflectors, but better than most other tapes. For initial testing, use a range of several yards/meters. If you get too far from something that isn't returning a strong signal it won't work, but you can also be too close, say under 3 or 4 yards. Car tail lights are quite variable, but you might be able to get a response on one as a quick test rather than waiting to buy something.
