I have a CED Millennium chronograph that I've tried to use off an on throughout the years, and I've never been able to develop a knack for getting it to reliably work whenever I want it to.

Tonight, I had it at the indoor range, with plenty of light (two bulbs almost directly overhead).  It wouldn't pick up anything I was shooting.

Ideas?

You ideally need natural light.   Indoor lighting will mess with the sensors, something to do with the hertz of the electricity and bulb used.  I see my green Chrony go whacko (display runs wild numbers) when I turn it in the house or garage, but settle to zero when I aim the sensors out to the sky.

Something I like to do is set my chrony in the shade,,,  but the sensors have clear blue sky above,  and try to use 10-15 ft from muzzle to entrance of sensors, and shoot straight  through.

You need a 100 watt incandescent flood light about 4 feet from the top of each screen, pointing down.  No other light will work.

They work on a bright day with clouds or direct overhead sun.

I have the same CED and I rarely have issues with it.

Passing clouds, fading evening light, and flying pests are my greatest nemisis.  That and short life of 9V battery.  I always use the white diffusers over mine though.

What about using it indoors?

They sell special lights for indoors for a reason. I just bought the CED, but it's been to damn cold to use it.

Oh, I'm sorry I didn't catch the indoors part.  I haven't had access to an indoor range in 15 years.

The CED catalog has a light kit but at that point you'd better have an AC setup to power it.
