| I've done some more testing, and I still can't simulate the problem. I have tried two different heads and several HID lights. I have stacked lights on the head including dual 24 watt video lights.
So at this point I don't know what we're dealing with. It could be radio frequency, electro mechanical, or magnetic. But I can say with some comfort that it is not a normal output from an HID light.
If it happens again, there is no need to reset the primary controller. It is unaffected by the pulse.
All that happens to the HUD is that is recalibrates unsuccessfully.
I have been told that RFI does not propagate through water, if this is RFI, so it is unlikey to be a problem in real diving conditions.
I will continue to build electronics that might be destroyed by a nuclear blast but can survive being dropped.
