Had one. Never used it. Rather shoot than keep score. YMMV.

Guys at the Club have them and love them.
I think Zeus has had one since they first came out.
Guessing he'll chime in....

The literature on it reads real good, I’ve been drooling over them since they came out Axe, might have to pull the trigger on one this summer. I don’t think there is any down side to these units, other than they appear to be more compatible with PC than my Mac. If you go for it, please give us the details.

Stan..... Lee is using the LabRadar chronograph in conjunction with benchers. I asked him to measure deceleration of our Bradshaw-Martin cast powder coat 194 SWC GC .357 Maximum. My impression has been the bullet gets downrange quick, but it may be no faster than some other bullets. The LabRadar can measure velocity in increments to 100 yards. Deceleration is a function of velocity as assuredly as of ballistic coefficient. Air resistance compounds with velocity rise.
Not sure why bench resters use LabRadar at matches, beyond bench shooters strive to eliminate variables. Convenient setup is a huge advantage. Bench resters don’t seem obsessed with velocity for its own sake. Various personalities addicted to the declarative sentence (insecurity, perhaps?), claim a bullet achieves its best accuracy at a certain velocity. For which I await explanation of how a bullet that starts @ 1,600 fps continues fine accuracy----having crossed the "sound barrier”----down to 800 fps, and below. In fact, if a bullet dropping transonic lost accuracy there would be no such thing as a good silhouette revolver.
Nor should one directly correlate low Extreme Spread or Standard Deviation to accuracy. Yes, a high extreme spread deepens trajectory on the slower rounds at long range. Yes, a high extreme spread causes vertical stringing with big heavy bullets, in rifles as well as handguns, but this is a measure of BARREL TIME, not accuracy. (A slow heavy bullet exhibits longer barrel time, raising departure angle higher at bullet exit.)
Check with Lee.

We use them all the time. Even when shooting an ELR match. If you see your velocities start to take off, then you know the data you have for dope is gonna change fast.
I love mine. The new apps set up for using and controlling it with your iPad are nice for arming it etc.

You guys looked at this chrono? The literature on it reads good. Ran across a family using one at a public range last year. Watched and talked with them at length about it. It was easy to set up and never missed a reading for the several hours and multiple calibers they were using. If I ever wear out (or shoot) my Chrony, I'll be buying one! |

You guys looked at this chrono? The literature on it reads good. ONCE YOU GET PAST THE LEARNING CURVE IT IS VERY EASY TO SET UP AND USE. HANDIEST "CHRONOGRAPH" I'VE HAD IN 40 YEARS. |

Only down fall I saw was it wont run with 20's and 17's. Both of which I have been playing with a lot as of late.
