I have for sale a Linhoff Profi-III ballhead. it is as new except I do not have the quick release plate. You can get one from B & H photo I believe for about $70.00. This beautiful head retails for over $1100.00. This one is used but there is no indication of it. It has independent pan lock. a tension adjustment on the ball head movement. accepts a 3/8" tripod screw. How about $650.00 including shipping CONUS. Over seas ok we need to get together on shipping.
