| WE have tried them all, and there is nothing that comes even close to an Oehler.
Do yourself a favor, and buy the best. |

Gee, that's exactly what I did, except I haven't bought the Oehler yet.
The nice thing about the shooting chrony is that it easy to set up, and they do give accurate readings. The only problem I've had is with the sun at an angle, one of those uniquely Alaskan issues of the mid-day sun still being low in the sky during winter shooting sessions.
If you can afford the Oehler off the bat, go that way. It is the only unit I haven't heard anyone complain about. It is also the only unit I'd classify as an industrial measurement device as opposed to a consumer electronic device, which is what all the other units are built as. |

| Bruno Shooters Supply has it for the same price as Oehler does, so just order it direct from the manufacturer.

Having never used a chronograph, why would the sunlight matter? 
Does that mean that you can't use a chronograph in the shade?
I've seen that a local importer sells CED Millennium chronographs. Are these any good, or is the Oehler far superior?

| Rikard, You have to explain this to me with very small teaspoons! I have no experiance withs chronographs whatsoever! Although I am planning on starting to reload rifle cartriges in the near future and am thus curious! How does light play a role with the chronographs measuring of speed? Are there lightsensitive detectors or something? What are diffusers? Sorry for the stupid questions...  Erik D. |

| According to Oehler (paraphrased):
In a chronograph, two photodetectors are spaced at a known distance along a bullet's path exposed to ambient light from the sky.
The diffuser eliminates light reflection from the bullet which can cancel the "shadow" of the bullet and prevent the photodetector from responding to passage of the projectile.
Make sense?

Erik,
I forgot the international audiance and my Norwegian kinsmen, as it isn't a uniquely Alaskan issue, plays havic with all of us in the far North, don't know if anyone is far enough south to have the issue.
I'm not an expert on how chronos work. I do know what problems I've had. Actually shady days seem to work best. The difuser keeps overhead bright sunlight from directly hitting the light screens. The problem in the winter is on sunny days, the light is coming it at an angle, and the difuser does no good. |

| George / Paul,
Thanks for explaining!
So have I understood it correctly that it is actually better that the chrono is in the shade and not direct sunlight, where shadows aren't so much a problem?

| Yes, as long as there is a fair amount of ambient light. In other words, it may not work all that well on a gloomy morning or at dusk.

|  Any direct light source can play havoc with the readings. We found this opaque cover on the screens works very well. |

| Just remember, there are only two kinds of people with chronys. There are those that have shot it  , and those that are going to shoot it  !!!! |

| Spring,
wait about 3 weeks, for me to have finished some (statistically insignificant) testing on the chrony, the pact pro, and a couple oehlers.
Since they ALL state .5% (.005) error rate, I would like to do a head to head on this, for VELOCITY, as this should serve the average joe just fine

| I have a CED Millenium that I purchased from Dillon. I also got the infrared attachment and can shoot in any light condition, even in the dark. |
