Martin I assume B is the 'right angle' corner of the triangle formed by the trees. In this case, if I understand you correctly, you have described directions that are much more biased to particular orientations than Beats instructions (The diagonal plan and sloping directions are omitted). The instructions do say the particular orientation is not important, but given the troubles I am having I would have thought a uniform three dimensional spread described by cube faces and vertices would be less risky.
On the other I can see it is easy to implement in the field without any special equipment provided one can brace the disto-X against the tree and not bump it when the button is pressed.
I'll give it a go.

It is Beat's trick, he showed us it in Vercors. You are right, ABC should be +- right angle. Martin
