Inappropriate comments and flames will not be tolerated and will be deleted. Thank you for your cooperation. Tom, I have been using a Topcon APL1 robot with TDS data collection for two years. I have used the robot on large farm surveys, sewer and highway staking projects, small and large topographic surveys, subdivisions and ALTA surveys. At least 90 perecent of the time I work alone.
Robots are perfect for jobs which require lots of shots without moving the instrument much.
I really can't think of many other cons. Just demo all brands if you get a chance, but try to buy from a dealer who really knows something about them. Feel free to e-mail if you have any questions.
