Digger

I think it's fairly normal, and comes from fear of the unknown. They understand the position they are in, and when these boxes come along, with lots of technical descriptions and a totally different way of working to what they're used to, a lot of DOs will find it easiest to brand them as death machines and avoid getting into the debate at all.

I found a lot of the doubters, if you want to call them that, were won over to curiousity once they tried the unit in the pool. I let them try it, and explained quickly how it works, and they understood and tried it out. I don't think they'll be rushing out to buy one, but if they do a few dives with me they'll probably accept that I'm not likely to die at any moment, and that it's not that complicated!

Digs.
