A member in good standing of Benro's new generation of B Series professional ball heads, the B3 Triple Action Ball Head uses magnesium-alloy components for better performance and lighter weight. The B3 has a triple action design featuring panning and locking knobs, and, a long, precise friction adjustment. Also, the head has a graduated panning scale, and an Arca-type QR adapter with a PU-70 QR plate. It can handle weights up to 39.7 lb, and only tips the scales at 1.5 lb itself.
