The TA-3 Leveling Base with Low-Profile Knob and Platform with 3/8"-16 Stud from Really Right Stuff can level horizons for filming during a video shoot or for landscape photography. Your tripod's top plate can be replaced with the TA-3-VB or other industry standard 75mm video bowls. Therefore, the leveling base adapts right into the bowl, and it gives you the capability of leveling your horizon +/- 15°. Furthermore, with the built-in 12mm bull's-eye bubble level, it ensures your camera is leveled every time.
The top of the leveling base features a low friction anti-jam polymer plate with a 3/8"-16 male stud. Therefore, ball, gimbal, and fluid heads with the same female thread will screw directly to the base. After locking the level's low-profile knob in place, the base supports up to 25 lb of gear without slipping. In addition, the CNC machined 6061 aluminum leveling base has a Type II anodized finish, which makes it scratch- and corrosion-resistant.
