A member in good standing of Benro's new generation of B Series professional ballheads, the B3 Double Action Ballhead uses magnesium alloy components for better performance and lighter weight. The B3 has a dual action design featuring separate drag adjustment and lock knobs, long, precise friction adjustment, a graduated panning scale, and an Arca-type QR adapter with a PU-70 QR plate. It can handle weights up to 66 lbs (30 kg), and only tips the scales at 1.5 lb (0.7 kg) itself.
