SBH-300 is a lightweight ball head constructed of solid, strong magnesium alloy. It includes two bubble levels, 360-degree scale, fine-tuning knob, a safety lock for extra stability, and a panning base. A special universal VANGUARD quick shoe for body/lens is also included that is appropriate for any lens up to a 300 f2.8 size. It weighs 1.65 pounds.
Basically a good, reasonably lightweight, and rather large ballhead (making it easy to operate with gloves, etc.)
