We will need the following

2 x tapes
Line
Arrows
Plastic Boards (sketching, drawing etc)
Suitable paper

Cameras Still
Cameras Video
Laptops a plenty

The cameras/lights I know are covered. JAG has a large explorer reel which we ought to use, as its still virgin, and I have a large no of unused line arrows which can be used to mark the line.

I think David has 1 x tape, can I ask the rest of you to sort out three/four plastic boards (a la NAS) the paper, and 2 additional tape measures.
