The GSLVLS Leveling Base from Gitzo is a basic leveling accessory designed for use with the Systematic series of tripods.
Ideal for flat base tripod heads, the GSLVLS is designed to help users level a standard tripod or fluid head in order to maintain level horizons and reduce time-consuming post processing corrections. Use of the leveling base requires a 75mm ball adapter which is available for all series 3, 4, & 5 Systematic tripod legs.
The leveling base features a lightweight aluminum construction which adds a negligible 0.8 lb to your existing tripod setup. The standard 3/8"-16 top mounting screw will accommodate most tripod heads and is connected to a tightening lever to secure the head and prevent unwanted twisting.
