Kirk BH1 Ball head

Kirk manufactures the BH-1 ball head for precision and rugged stability...guaranteed! Featuring the same efficiency of design and rugged construction that make other Kirk products so popular, the Kirk Ball Head features our Satisfaction Guarantee and Five-year Warranty--the best in the industry. Of course it's American Made right in Angola, Indiana. This ball head features silky smooth ball-and-socket action for complete control--just by releasing and locking a single knob. Two smaller knobs control the 360-degree panning base and the amount of ball friction. The Model BH-1 features a universal quick-release platform with a built-in spirit level that accepts all Arca-style plates and mounts.

All external components are crafted from tough 6061-T aircraft aluminium including the solid, captive-design knobs, and the internal metal parts are stainless steel and brass to avoid corrosion.  This could be the last ball head you ever need to buy.
