I could not figure it out, and I turned around, and the glare from a parking lot full of cars was pretty bright. I had trouble the other day trying to get it to lock on me. It will sometimes lock onto other surfaces, but most robots will unless you are using an active prism. It has reflectorless, but it is limited to around 275'-300', depending on the surface. I use it with both onboard batteries, and an external battery as well.

I use it all the time, and have very few issues with it. I picked up a CTS-3005 with reflectorless for manual traversing and reflectorless ability. I have had zero problems with my gun and will more than likely run it until death do we part. The 810-815 were out shortly thereafter and had reflectorless capabilities and then I lost track of the progression. I believe this was the next generation after the APL series.

I have a GTS 802AR I purchased new in September, 2002. Also, if you have any personal experience of how good or bad a particular model was or is, please feel free to comment. But after that, there are an assortment of different model numbers and I don't know which order they came out. I am looking at used Topcon Robots and I was wondering, can someone give me a brief history of the models of Robotic Total Stations that Topcon has produced over the years? I currently have a Topcon AP-L1 which I believe was their first production model that was followed by the AP-L1A a few years later.
