I have in excellent condition a Foba tripod with a geared center column which can also be used as a side arm. It has never been used outside, in fact the studio was carpeted so even the feet are like new. Everything works smoothly. There is minimal wear one of the legs was tapped up in the photo but I removed that. Short of some glue from gaffers tape it is excellent. With the geared column fully extended it is 78" tall. Since this is part of the Foba system the the bottom leg section can receive a Foba Combitube. This can be used to extend the height of the tripod another 3-4 feet.
