Indoor Chronograph usage
A buddy of mine and I are going to our range tonight to do some 100 yard load testing.

"At night?" you say? Yes.

We have a 100 yard tunnel range

My question is to anyone who has used a chrony indoors. Is it possible?

The shooting room has power and lights. My idea was to bring a flourescent tube light and extension cord and hang it over the chrony.

Do you think that will work?

Unless you have IR screens you won`t have much luck. Indoor lighting cycles with the current and tricks the screens into thinking a bullet is whizzing by.

Why yes! Yes it actually IS possible!

If you are using a Shooting Chrony, you need the Chrony indoor lights. As the former poster pointed out, florescent lights flicker and screw with the Chrony. Chrony make a set of incan lights that affix to the shooting screens and over-ride the florescent bulb flicker.

How do I know it works? I have a set of the Chrony light fixtures. Here's the link for Midway...

Surely Mr. Woods has a special Thingy to allow chronographing in the house. rotflmo

Ask Michael458. He seems to do a great deal of it----Terminal bullet performance---in the big bore forum.

I use a shop light with a quartz bulb and sit it on a 6 foot ladder pointing down at the chrony. I get the same velocities as when I am outside.

I have a special thingy, it called a Pact
Chronograph. I simply put the skyscreens on it, and it works fine under flourescent or incandescent---don't know what kind of chrono you have, but give it a try--your going shooting anyways!

BTW, if I was going to buy a new chronograph, I would buy a CED Millenium...saw a guy at the range with one--Sweet.

Before you go to the range switch your chrony on inside near a flourescent light. This sort of light plays merry hell with a chrony, the read out continually changes of its own accord. Just will not work. Well mine doesn't and yet it has given 30 odd years of faithful service on the range but switch it on in the workshop and it goes crazy.

I used to shine this big cordless spotlight on my chrony and it solved any issues. It was nce because you could use it outdoors in the evening when I'd also get erroneous readings.


for every hour in front of the computer you should have 3 hours outside

CED has an indoor IR lighting set up.
It is as good as anything on the market.

CED M2 Chronograph
