I am not a surveyor, but this tool is very easy to use and is well made, even though it is made in China. The only improvements I would like to see would be replaceable reticles and perhaps variable power on the scope. There is some lens flare when looking towards the sun, but it is not a significant problem. Maybe the best feature is that the system remains stable and aligned in use. It does not wander around while handling the unit. All moving parts fit snugly, but do not bind so it is easily repeatable. That is very important. My unit did not have a level to pre-level the tripod. The manual seems to indicate one is included. I had a small bubble level and that is working well to rough level the tripod before leveling the transit.
