Nikon, self leveling/automatic optical levels are nice too, I cannot remember the optics on the ones we were using, I bought 3 of them for the company I worked for in between'01-'03, they were $800 or so, I did not like the aluminum tripod, fiberglass or heavier type was much better. I've used these in both site work and determining elevations off bench marks placed on columns on high rise jobs, it's got the self leveling bubble in a circle, the optics are important, as it makes it so much easier to take an accurate reading, one job we were on, had string dimensions on the drawings as small as 1/16", so even the increment mark thickness's on the darned rod were important to incorporate into your reading. It's a great tool to have, and I've got to get another one for my jobs now, would get one of those again, and you do have to take care in using them/keep calibrated, clean etc., our survey instrument supplier used to provide that service, I used to get them done before every job started and I was the only one handling the instrument on my jobs, so I knew it had not been dropped or tossed in a gang box. Instructions were given to others to do the same. Even lower cost models, you still need good optics for longer distances, not sure what pro's and or surveyors think of the Nikon's but I thought highly of them and depended on them to layout some intricate work on my jobs. Most contractors were using them too. They were great for site work as ground vibration from say a dozer working nearby, or other disturbances are not supposed to knock it off level, supposed to be the reason they call them automatic levels, I could be wrong, but I thought they made a good instrument to fill the need for elevation work etc.
