The green S3 Lite Tripod from Fotopro is a 4-section aluminum support that has a twist leg lock system that allows, along with the rapid center column, for a maximum height 50". Collapsing the legs completely enables the tripod to go as low as 18.5", and the center column can be removed and reversed to get even closer to the ground. The built-in ball head has a single knob that locks and re-locks to control the movement of the head. Therefore, the ball head can be positioned at a 90° angle and rotated a full 360°. The ball head has a spindle-locking wheel that you turn to attach a camera to the top of the head, and it supports cameras weighing up to 5.5 lb.
