    Primary Arms Advanced Micro Dot- MD-ADS

    Very nice! I am interested in hearing what the result is with the new battery. I'm inclined to change out a battery every year or so, not to wait the full 5+y for it to die. As long as I can rely on it beyond a year, then that would qualify it for serious purposes.

    Nope, not too fancy. Very low low tech. In fact, it's older than I am. My dad built it in the 1960s from a Heathkit. Swinging it would almost work, if it was bright enough to see at swinging distance and not tumbling all over.

    Anyone interested in donating an MD-ADS to me, I'll put it on my oscilloscope to see if it's pulsing that LED output:)

    Since it was August when you posted that, have you had to replace the battery at all yet? I'm really interested in the 50k+ hour assertion as well.
