I hadn't realised before that the allen key is necessary to attach the head to the tripod and camera. I suppose it's a consequence of the head being so small.
It would be good if there was a way to have the key captive in the head. The really neat idea would be to be able to use the key as a panning bar!
We are also including with the Recon a 3/8-16 to 1/4-20 insert if your tripod has a 1/4-20 connection instead of the standard 3/8.
