The PROMASTER CH60 CINE HEAD uses the ProMaster dovetail quick release system (arca-swiss compatible). This dovetail Q/R can work with a host of plates and accessories from ProMaster and other brands. The plate included with this kit is long. You can slide it to find the best balance point for your camera and then record the number from the scale on top of the head to set up the same camera even faster next time. This Cine head also has an accessory attachment port (3/8” threaded) for connecting accessories such as an arm and external video monitor. The overall operation is very smooth and there is drag adjustment too.
