The head is attached to the tripod with a screw thread 1/4 "standard. You can replace it with another ball (with déclipsable tethering) for comfort. The ball is supplied with the tripod 100g, complete with tripod 700g ball
The middle tube is locked with a screw and can be mounted to a total height of 125 cm (in monopod mode)
Feet apart at 124cm tall supports a Pentax K3 (Though not get away: D)
Feet apart max 118cm and he is quite stable. He would miss just a hook to hang below his camera bag and ballast. (Average pTet to find one screw on the bottom?)
Folded it is 42cm from the tip of Ball to toes
The construction fulfills the contract properly support the weight. However it's very light and it must be breakable if you type in.
