pros... magnetospeed you can set it up without a cease fire ,small,portable cons...affects point of impact,so no shooting groups,,some say it doesn't,but on my rifle it does
pros...radar, i think you can get readings at different ranges? not sure,don't know much about them,no change in poi cons.....thousand ish dollaryroos,need a cease fire
pros... shade, cheap,they work,no change in poi,been around for years cons..you can shoot them, cloudy day can mess them up a bit,need a cease fire
been a few threads about crony's but this is my take on them,,,,i have the magnetospeed,good bit of kit,would be better if it didn't change the poi

I use a Competition electronics ProChrono Digital. I bought the link unit for it as well but have never played with that.
My old one lived out in the paddock under a plastic crate and eventually died. But as it did everything I wanted from a chrono I replaced it with the same model.
I can at least say that both give me similar measurements, so they're either accurate, or similarly inaccurate, which works as well
I shoot loads from 250fps to 4400fps through it. I don't use the shades so I tilt the sensors toward the sun to get the best consistency.

Looks pretty good.
From the website it's E250 or A$405 delivered, or A$420 via Ebay.
It's significantly more expensive than some others but I'm not sure it offers anything they don't.
Personally I don't bother with any of the number crunching. I just need something that will consistently measure my velocity, nothing more than that. If it retains the string for me to go back through it that's a neat feature, but I generally note the velocity down when I shoot anyway. Sometimes I even write the velocity on the cases as I fire them. If I want to bother working out the average, ES, or ED, I can do those myself when I've finished. I particularly like the easy "set up" of the ProChrono, just sling it over my shoulder when I walk up the paddock, screw it to the tripod (which stays out in the paddock), or lay it on the ground if I'm prone, switch it on, start shooting. Dead easy. I don't use the screens and there's no bag or box to mess with.
I think I paid $180 for my first ProChrono, and $225 for the new one. Even that is a lot of money, in my opinion, for a device you are deliberately setting up in front of a high-velocity rifle
I would ideally like to just have the sensors in the firing line and have the electronics separated on a two-meter cable. I think my old one has only died in the display as it just throws up random segments, I might have a play with it. I did have a problem with it once, until I discovered a spider had built her home in one of the sensor slots

you could even ask someone who has one at the range if they would put a few shots threw there's for you
Bills Shed wrote:I run a base model Alpha chrono. It works, reliable, and it just puts out the numbers. If you want all bells and whistles, buy it. There is no "best". I mainly pull mine out if I want to do some low velocity work with a new projectile I have built. Even then it is an after thought as I want the projectile to hit my target and the speed is mostly irrelevant. Book specs will be close if you are working out of a book. I thought a chrony would be a great advantage but it really is a want and not a need. It can lead you to some load chasing, trying to get better results, consistency, etc,etc....but at the end of the day if what you have as a load works the velocity is a nice to know. Would I buy one again. NO. Another toy that does little work for my hunting/ culling needs. I do not shoot paper and a sub MOA is fine. All the tech guys may get a bit bent out of shape with this line of thinking but I say get out into the paddock and shoot. A well placed shot means dead, regardless of speed.

Absolutely Bill. My 303 loads are grouping fantastically so now I am curious about what speed they are doing. I have already decided that the best grouping load is now my standard load, and to be honest I really couldn't care if it runs at 1800fps.

WHere are you located? If you are in the CQ/coalfields areas you could borrow my old chronotech.
