Gee, Ian, do you really believe in that or just trolling? You have
about the same chance to get hit whether you look outside or fly blind
folded! What saves you is the big sky and nothing else. And all the
"threats" you think you detect are most likely non threats, the ones
which catch your eyes as moving targets close by. The real threats are
those which do not move and turned from a dot to full size in less
than 10 seconds. There are very few pilots who can honestly say they
had detected and avoided one of those thanks to just looking outside.

This is where I am sceptical. Yes, I am sure these things will give
lots of extra alerts - they'd hardly be worth buying if they didn't.
But we are not exactly plagued, world wide, by glider-glider
collisions, are we? So what this means is that pilots will spend a lot
more time reacting to false alarms (they must be false, because if
they weren't they'd end in a collision without the magic gadgets).

And what you think the reaction to those false alarm is? Looking
outside and scanning for the threat! Do you see a problem with this?
