Thread: Chronographs, what's the story

Close up of the small strip of printed circuit board with the LEDs on it.



Wildman that may be right, it may be possible to have too much light. I vaguely recall that cranking the LEDs up took the sensor circuitry out of it's designed operating range - a bit like trying to get them to work with direct sunlight. The LEDs on this one have a voltage regulator between them and the batteries so the light intensity can be adjusted. Feel free to PM if you like for other details.

Cheers, ta.

hi all
yeah, I know its an old thread but with recent experience and not seeing mention of my take on it....
l've found I need to take care on aligning the chrony parallel with the shot, one end higher than the other shortens the bullet path, hence higher (different) numbers.

Had a Steinert Superchronograph and it worked well regardless of the light conditions as it's sonic based. A little fiddly setting it up as both ends of the chrono must be dead parallel to the bullets path. Now use a Labradar which is easy to set up.

I have an old Canadian CHRONY F that is free to anyone that wants to pick it up. Just needs a 9v battery. Live 100m from SH1, Tokoroa.
