Hi Ron,I was in the same boat not that long ago, looking at chronographs. After alot of research, reviews, and otherwise, I went ahead and got the ProChrono Digital. Many factors went into my decision, and I'm really happy with the unit. It's been flawless so far, and hasn't missed a shot indoors since I got the light kit. It'll store up to 10, 99 shot strings if you want. I like to shoot 15-20 shots normally, to get a really good average of how a gun is performing. 99 shots is a bit much, but I have the option of going that far if I want to in one string. The light kit works great, and consists of 36 infrared LED's per arch, and one red one to indicate power to the arch, since humans can't see IR. The side benefit is no visible light entering the front of the scope to cloud your view. It just sits there nice and dark. The red LED is the only indicator that the lights are even turned on, but you can see them with most digital cameras/phones if you have one. I prefer the non-folding case for a couple of reasons: sensor alignment, and rigidity. My opinion is that these things are precision instruments, and a solid case offers protection, and guaranteed alignment of the sensors, which are exactly 12 inches apart, center to center. The skyscreen guide rods are solid aluminum, 1 piece, instead of a sectional design, like some others. The case, rods and skyscreens are quite sturdy, with no slop or play. It also offers a larger shooting area or sweetspot, if you will, then some other brands I tried. Just get the shot above the sensors, and anywhere between the rods, and it will score.I mount mine on a tripod. I'm a photographer on the side, and I have several to choose from in my gear, but any inexpensive one will do, really. Being able to change the tilt and elevation is nice, instead of setting it on a table or whatnot, then having to change my shooting position to compensate for however the chrono is positioned. I'd rather shoot comfortably, and adjust the chrono to be wherever the pellet is going to fly.For 50 bucks, there is software and a 20ft. (I think) connection to a Win based computer to log all sorts of data, but alas, I don't run Win, so I haven't used that option yet. Anyone with RadioShackability could make a cable of any length.Lastly, it's one of the few pieces of electronic gear I've bought in the last decade that's made in USA. That factored into my choice very strongly. That's my mini-review, and no I don't work for Competition Electronics, but I have used their shot timers at some pistol matches in the past. StephenThanks for the input..I have a mac laptop so the software is not for me..From other posts this seems like the way to go.Just have to shop around for best deals.
