I'm looking into a Leica Rugby Laser to attach to my dozer. I think I'll probably go with the 400 DG dual grade. I wanted to see if anyone has one of these and what you think of them. I believe these are compatible with Leica's Automated Machine Control systems. I'm not interested in that right now, but may be in a few years if the work presents itself. For now, just the dual slope.I'd also like to know if anyone who has one of these systems, what you think it should cost, or did cost, to buy the complete kit with a mounted pole on a blade. AWJ- I saw in some searches that I did that you were looking at one of these at one time. Did you buy one of these, or something else? I'd like to hear your thoughts. Thanks.
