Cambo PCH Geared Head
The Cambo PCH tripod head is a welcome addition to the geared tripod head market, When I wrote this review it fell between the Manfrotto Pro 405 head that I had used extensively in the studio and the Arca Swiss range. The comparable Arca model was the D4 at a similar price point while their top of the range C1 cube, probably the ultimate in geared heads, is considerably more expensive.
My own tripod head choice is the Arca Swiss P0 model, if I was buying a geared head I would look very seriously at the Cambo reviewed here.
