I've been wondering what is your range for a Trimble robotic total station? I have a 5603 with the super prism and I don't think I get more than 1200' with it. Shouldn't I get more? I do have the power stick but I don't think it works it probably should be recelled. I don't think it ever worked from the dealer but I didn't catch it until it was out of warranty. But does the power stick make a difference?
