The new HM-3 upgrade converts the Jobu Lightweight gimbal (BWG-LW3)
into a Jobu Heavy Duty (BWG-HD3). The kit converts the standard
sidemount lightweight (quick release mounted sideways) to a top-loading
The top-loading swing-arm improves balance characteristics of your
gimbal by allowing balance in the vertical direction. It also centres
all of your lenses as this function no longer depends on the height of
your lens foot or diameter of the lens. This makes it more useful for
panoramic photography, makes setup safer and faster and improves overall
handling and use of the gimbal.
Please note: In order to DOWNGRADE a BWG-HD3 to a LW3, you need simply purchase the QRR-STD, or QRR-Pro quick release kits.
