The Monoball P0+Hybrid with Quick Set Device FlipLock from Arca-Swiss is an unconventional ball head with minimalist design built with portability, ease of operation, and performance in mind. The Monoball p0+ has an inverted, aspheric-shaped ball, which increases resistance as the camera is tilted further from the horizontal plane, stabilizing a heavy camera or long telephoto lens mounted on the head. Turning the highly visible knurled collar on the body will lock even a large camera firmly in place; no need to fumble for the locking knob that may be out of sight. The unique design of the head has negated the need for any lubricating grease that can work against the user and produce head creep, which can lead to a tripod and camera tipping over.
The p0+ incorporates two self-locking geared leveling mechanisms that can be continuously adjusted by up to 10°, which are arranged at right angles on the x-axis and y-axis perpendicular to each other. This allows the head to be quickly leveled without having to reset the tripod legs. The p0+ has also incorporated four locking points into the panorama swivel, which ensures that the fine adjustment of the gear can be carried out at a neat 90° angles.
Inside the head three locking planets clamp firmly around the ball, applying even force on all sides. This design ensures that all camera movements are smooth in any axis. The inverted ball design provides greater stability in keeping the camera's center of gravity closer to the center of the ball. The p0+ allows for a full 90° of tilt. Placing the head's panning system directly below the camera ensures that the panning motion is directly aligned with the camera itself and does not deviate from the same plane.
