Re: controlling lighting with chrono?

Went shooting yesterday and set up 3 chrono's in-line with eachother under a pop-up ez-up shade. Worked great all 3 fuctioned pretty well ( one read a duplicate 1 time.)

Re: controlling lighting with chrono?

I have found that consistant light whether it be overcast or sunny outside works the best. It is hard to have the same even light day after day, but a fairly transparent material around the chrony so that the light is even worked the best for me. I think the only way to eliminate the issue is to build a box around the chrony that keeps most light out and use a seperate lighting system that you can control. I think strips of LED lights that would run off a 12 volt battery could be the fix. I am going to try this build this summer. Anyone else tried this?

Let us know how that works. I was satisfied with the ez-up canopy, worked well and was well, EZ! It would be difficult if you were by yourself but not impossible you would just have to stake one of the legs down to open and close it by yourself.

Re: controlling lighting with chrono?

The LED lights that run off a battery is basically what you get when you order the IR sky screen set for a CED Millenium chrono. The catch is... they are IR, so you can't tell if its on or not.

CED attempts to get around this by putting some visible red/green leds inline to show battery status, etc. They don't really light up enough to be visible (for me).

Being pretty far north (for the continental USA, not counting Alaska of course!) we get some steep sunlight angles... the sky screen shades don't do much good, and sometimes even with the IR lighting I have problems clocking shots - I think the direct sunlight coming in at such a steep angle interferes with the weaker (relatively) IR lighting coming straight down. Then again, I might be all wet on this one. I'm sure there's a lighting guru out there just waiting to chime in...

A few years ago I'd chatted with some action pistol shooters, and they described the chrono box they used at matches to certify guns as 'major' or 'minor' power levels... basically a plywood box with two CED Milleniums back to back, and interior lighting (incandescent, as they had 110VAC handy at the range).

Sounded like a neat idea, and the wife got me a heavy duty surveyors tripod from HD last Christmas... I was going to build my chrono box, but now I need new side screens because the wiring jacks are hosed.

The ez-up pop-up sun shade sounds like it might be a good bit easier...

Re: controlling lighting with chrono?

milanuk beat me to it...USPSA and IDPA major matches typically used IR screens inside a box back when i still had time to shoot that much. 2 CED chronos back to back setup this way made for a pretty hard to beat setup. It is a lot of trouble to tote around though.

I use a CED and almost always use the IR screens. It is a rare thing that it misses a shot and seems to stay fairly consistent day to day.

I used to rely on a chrono more than I do now. I will shoot a ladder through one getting started with a load and then use on paper performance from there on out. If the load has a bunch of vertical then I know the same thing as if it has a high ES.
