Manfrotto 676B Digi Compact Black Monopod (~60" Extended) -Near Mint in Box-
This is a nice heavy duty monopod made by Manfrotto. It is relatively lightweight and very sturdy, this would be an excellent monopod to give you lens support while shooting with extremely long lenses in the field. I use a monopod (not this one!) with a fluid head attached for my video work when I'm in tight spaces.
It has a 3/8" mounting screw for a tripod head and supports up to 10 pounds.
This one is in near mint condition in its original box. There is only very light signs of use. The locks are all sturdy and secure and everything works perfectly. It is ~60" tall when fully extended.
This is a nice one.
