Actually if you watch the Bear series you will notice that the Survival consultant is the Bushcraft Expeditions Team - Woody, Ross and Stani.
All we have to "show" that the Bear has experience is the TV programme which as we all know is heavily edited and where sometimes they order pizza for their motel rooms.
Strictly speaking all we can surmise is that Bear has considerable TV entertainment experience and probably has a free-fall parachutists ticket of some kind.
As for Ray, yes he has experience operating as a survival school and considerable TV bushcraft demonstration experience. But I have not seen an unedited handdrill demo yet.
I have never asked for any persons qualifications. I sometimes write about people who offer bush trips or survival training in this part of the world and have yet to meet any who were lacking expeirence - whether an illiterate native or an ex-squaddie.
Actually one should ask for Wilderness or Remote Areas first Aid and casualty evacution
