Our Acratech GP Ball head is uniquely designed to function as a ball head, a gimbal head, as well as a leveling base. Named "Best Buy: Practical and Versitile" by DP Review April 2015
It weighs only 1 lb (454g) and has a 2 3/8 inch (60mm) base diameter.
Although it boasts all of the benefits and features of our GV2 ball head, what really sets the GP apart from the rest of our ball heads is that it was designed to be used upside down (image #2), which allows the ball to be used as a leveling base when taking stitched panoramic images. This eliminates any need to carry a separate leveling base in order to create accurate stitched panoramas, as you'll be able to pan paralell to the horizon even when using your tripod on rocky or uneven terrain.
This ball head includes a quick release clamp with either our double speed rubber knob, or a locking lever. It also includes a large bulls eye level and detent pin.
