Gitzo G2270m ist a joy to use! This head has super smooth movements and the locking is pretty easy, you do not need much effort. This is the best pan/tilt-head and best head in general that I have used so far. Do not own one myself, but intensely used one a friend had allowed me to use. Unfortunately it felt a little bit too small for my SL66 and I finally went for the bigger G1570m, which is not that smooth but I feel more comfortable with it. The smaller G2270m would be well suited for your rangefinder I suppose. I have used the version with the large plate, but there is also one with quick-release.
Best regards, Benjamin
