Arca-Swiss Monoball P0 tripod head (Model P0 801213) with a built in panning system and attached Slidefix QS quick release system for sale.
The head is very solidly built and is rated to support 20 Kg (44 lbs) yet weights less than 300 grams. It has a 90° tilt range and a 360° panning range. There is a built in bubble level on the top surface. It has a very smooth action and is a real joy to use. It is 2 years old and has only been lightly used. I am selling it to upgrade to an RRS tripod head that will connect to my RRS camera plates.
Included is one Arca-swiss Slidefix QR camera plate 48mm x32mm (#802265) which will attach to most cameras. Additional plates specific to most popular cameras are available from B&H.

This head and plate cost me about $425 CND, it is offered for sale for $265
Thanks to everybody who viewed/contacted me about this tripod head, it is now SOLD.
