The Jobu Design HM-Pro2 Horizontal Mount Upgrade for BWG-Pro Gimbal Head enables you to switch out the swing arm of your existing BWG-Pro Black Widow Gimbal head for a stiffer, stronger and more smartly designed successor arm. In minutes you can install the new arm using the included hardware and a 5/32" Allen wrench (not included).
The redesigned arm features not only the expected Arca-style quick-release clamp, but also a dovetail design for its vertical portion, which enables you to attach Arca-Swiss-compatible accessories such as flash brackets. The quick release is now integrated into the swing arm itself, which has allowed Jobu to reduce the number of components, increase the strength and improve the finger clearance of the redesigned arm.
The stiffer arm is recommended for supporting long telephoto lenses on your Gimbal head, including 600mm f/4 models and even larger lenses, too. The swing arm upgrade is CNC-machined from solid-billet aluminum and hard-anodized for a durable finish.
