The Acratech GV2 Ballhead/Gimbal Head is a sturdy, heavy duty, yet compact ballhead that is similar in design to most conventional ballheads (unlike the unique Ultimate head). However, the GV2 model has been improved so that it can be locked down when the head is in the 90° orientation, which effectively turns this ballhead into a gimbal-style head. This will now allow the camera to pivot around its center-point, gimbal style.
The GV2 features a low profile design, and sports all-rubber knurled knobs that are more comfortable to use, especially in extreme weather.
The built-in industry-standard Arca-Swiss style quick release clamp makes it compatible with the many different plates available from Arca-Swiss, Kirk, Wimberly, Really Right Stuff, Foba, Novoflex, etc. The clamp also feature a spring-loaded detent pin that projects into the pockets or windows that are cut into the bottom of most manufactures (Acratech, Kirk, Really Right Stuff, etc.) quick release plates. This detent pin will prevent the plate from accidentally sliding out in the event that the knob is partially loosened.
In addition, this model uses a "leveling" q.r. clamp, which features a large 15mm bulls-eye bubble level that extends out of the side of the clamp.
