The miliboo 501 Carbon Tripod Kit includes a compact travel tripod and a flat base fluid head with a 3/8"-16 thread on the bottom. The carbon fiber legs of the tripod make it highly lightweight as well as corrosion resistant, and the flat base of the fluid head allows you to efficiently move the head back and forth between the tripod and camera supports such as sliders that have a matching 3/8"-16 mounting screw. The fluid head supports up to 17.6 lb loads, while the tripod on its own supports up to 22 lbs.
