For medium-heavy camera rigs for drama production we have a fully-serviced Sachtler Video 18 III 100mm bowl head. Comes with quick release tripod plate using 1 or 2 large 3/8" screw threads.

This tripod head is compatible with our Sachtler 2 D tripod and can be used on our Losmandy Jib with the 100m adapter

The head can balance light or heavy loads up to 18kg with 2 switched in/out variable stages of counter weight (and no counterweight setting too) and a long head plate movement for front-back camera balancing.
The head also features 7 horizontal and 7 vertical grades of fluid drag.

An ideal tripod head for our Blackmagic camera rigs!
