Ok I have just learned that the Multi Use Monocular (MUM aka NVM) made by Insight Technologies can take up to 4 seconds to light the tube after... the switch has been engaged. Yep you read that right the MIL spec allows for this delay. I beat my head against a wall trying to figure this out and even sent a customers unit in to get checked for this defect only to be told "Ohhh that's normal." I could not believe that.
Well my opinion of the MUM is taking a nose dive.
