| For years now I had to listen to people saying that the military testing performed on the PRISM Topaz and Invader didn't apply to civilian divers, that those tests, including EMP testing, are not important.
I truly hope some of these naysayers are reading this thread, as it should change their mind. With electronics for underwater lighting getting ever more powerful, these effects should have been and need to be taken into consideration. We are talking about a life support system here, and using cameras and lights is a common reason for the use of rebreathers.
At first I considered to respond with a new thread in the PRISM section, but as this is the General Rebreather Forum and the subject fits, here it is:
The PRISM has passed full IV & V (Independent Validation and Verification) by the NAVY and to their standards. Even a coast guard flash fired into the battery/electronics compartment did not harm the electronics or prevent them from operating. At 10 volts/meter the electronics kept working and didn’t even need to reset.
The maximum exposure was 200 volts/meter. That's enough power to light the LEDs in the HUD up (even with the battery physically removed), but not enough to damage the electronics or prevent the unit from resetting itself, being fully operable within seconds and without operator action.
