Fine adjustment works brilliantly. Scanning from target to target at 100 and 200 yds was easily done. Much better than manhandling the entire scope. Only issue is with the stability of the tripod when adjusting the adjustment on my spotting scope (Bushnell Legend 15-45x60). Adjusting the focus on the scope at highest magnification shook the image so much that i couldn't see what i was adjusting for due to the shaky tripod.
Pros: fine adjustment
Cons: stability at high magnification
