magnetospeed,about $360? or the radar one (cant remember the name.labdar?) $thousand ish, or a shade one,heaps of brands, $200 ish

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 :thumbsup:

Thanks tom604 :D The magnetospeed is reliable in it's readings?

Im not sure about my magneto...
I get low readings for every rifle i have-not sure if its my mild-moderate loads yet.. i havnt been able to check it against a proven chrono...

On my rifles however, it doesnt change POI-well not to a notable distance for hunting anyway...but it does alter group size on atleast one rifle.

Depending on budget the LabRadar is also great. Not mounting anything to the rifle and sits on the bench next to you so easier to set up if you shoot at a range.

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.

Labradar has a couple of cons apart from the cost. It chews batteries at a phenomenal rate. You have to use an external power source connected by a USB cable. It can pick up the shooter on the bench next to you, if you change the settings it sometimes will not pick up your rounds. It cannot read velocities over 4000 fps. Apart from that they are very good.

So far the score is magnetospeed 1.5/2
LabRadar 2.5/3
ProChrono Digital 2/2

I should say that it was the price that got me with the prochrony, I think I paid around $180 with the lap top accessories that I've never used :lol:
if you were wanting the best it would be something else, I dont use it for reloading just for ballistics
it has not let me down and IMO has been worth every penny :thumbsup:

The CED-M2 is a pretty robust unit for the price.
https://www.cedhk.com/ced-m2-chronograph
Pro's:
The CED M2 Shooting Chronograph has been the OFFICIAL CHRONOGRAPH for USPSA & IPSC Championships for the past 20 years,
Price,
A range of accessories,
Full range of replacement parts should you lend it to someone not inclined to look after your gear as you yourself would,
Data collection and storage computer not down range to be damaged should the above happen,
Data can be downloaded straight to ballistic programme on your desktop/laptop. Comes with a basic programme, but a much better one can be had from RSI,
Voice Chip technology – Results can be heard as well as seen
Good customer support.
Cons:
Price, some people think that because of the cheap price that unit won't work as well,
Set up takes a bit longer,
USB connection to your computer only (not wireless),
Can be a bit savage on batteries if using cheap ones.

"The results achieved by ALL brands of Chronographs depend heavily on isolating variables which can and do effect performance. These variables include lighting, muzzle blast, location / environment of use, and weather / temperature among many others. It is important to become familiar with the effects that each of these variables might have on the results obtained and how to control them properly."
I have been using a CED-M2 for the last 10 years or so, and yes there have been a fair share of faults and errors, but on analyis of the problem it has been found to be one on the variable mentioned above and not any fault of the unit itself.

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 :-)

OK, I admit I haven't kept up with price increases over the years. I only paid about $200 AU for mine, was part of a hardware/software package that meassures velocity, chamber pressure and recoil pressure. Back then, $200 for a chrony with these features was considered in the too good to true category. A quick look at AU LGS's shows average price of around $300, give or take, still not a bad price considering. As to the features, you don't have to use them, and do the mental arithmetics youself, but some prefer to just push a butom and have it done almost instantly, horses for courses I suppose.
Anyway, Stoney asked for recomendations for chronos, and after ten years, thereabouts, of use with this unit I would, like you have done with your chrono of choice, recommend Stoney look at the CED M2.

Magnetospeed.

Love mine.

Once upon a time i found a review of popular chronographs, and the magnetospeed ranked quite high.

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.

I have a magnetospeed sporter bought this year, paid 250 for it from a LGS. At that price it was a no brainer.

Easy to setup, doesn't take much space and while the screen may not be as good as the bigger brother it is good enough. Does ES, SD, Avg, max, min.
Blame it on the phone auto correct

Thanks for the advice fellas, very appreciated. I will have to have a good think about intended use. I'm thinking that renting one from the range when I need it might be the smart thing to do.
