I've readings from 3000-8000 FPS even shot it 5feet away. Can anyone give me advise?? I use one, and find that it is really sensitive to the light level. Trying to chrono at dusk is a no-go, direct sunlight going in the sensors - no-go. I generally put a target over the top, white side toward the sensors - shading the sensors from direct sunlight, and I get good readings then. Mark K.

Do you know what happen when I get the funny 3000 FPS readings? Edited November 3, 2009 by Limited Custom Link to comment Share on other sites More sharing options...
Jman Posted November 3, 2009 Share Posted November 3, 2009 When I had one I found that 9-10 feet worked well for pistol. And, 12-14 feet for rifle. Like Mark K said, set it up in the shade. NO direct sunlight and you should be good to go. Jim Link to comment Share on other sites More sharing options...
Jeff686 Posted November 3, 2009 Share Posted November 3, 2009 5 feet is very close. You could be reading unburnt powder or other crap from the gun. Try 15-30 feet to see if they chrony settles in and is more consistent. I've got the same model, and I usually go as far as possible, but still close enough to read the numbers. Other posts are correct too, direct sunlight in late evenings or early mornings are more difficult. I've run mine against a couple other brands, and found as much as a 30 fps discrepancy, but the error was constant (always the same), so I'm not sure which one was correct.

Limited Custom Posted November 3, 2009 Author Share Posted November 3, 2009 10-15 feet is very far. The other brand works a lot closer. But will try out..... Sounds like I will need to buy another brand soon (after I shot it). Thanks guys Link to comment Share on other sites More sharing options...
Graham Smith Posted November 3, 2009 Share Posted November 3, 2009 I used one for pistol for two years before replacing it. My problem was the reverse - the only place I could set one up was indoors and for that I really needed a unit that had it's own light source. I did have it working using lamps and the sky baffles, but it was a hassle to setup. Other than that, I got pretty consistent results. Link to comment Share on other sites More sharing options...
