Sirui LE-60 Leveling Base
The LE-60 Leveling Base from Sirui fits between a tripod and video or ball head, and lets you quickly adjust and level the head independently from the tripod. It can be used with any tripod or monopod with a 3/8" stud. The LE-60 has a 2.4" platform with an off-set bubble level that can swivel 15° in any direction, and is rated to hold camera systems weighing up to 33.1 pounds. The top platform is compatible with heads with 3/8" or 1/4" mounts.
