Nice info! Can you run all 3 simultaneously so you can get the 3 readings for each shot? That might be an even better comparison.
I'm also very curious about Magnetospeed's potential to influence the shot. It would be interesting to see group velocities & POI statistics with Labradar alone (as a control) and Labradar + Magnetospeed. (Forgive me if this was already discussed; I admit to skimming through the thread) |

I think I've just about talked myself into the Magnetospeed Sporter. It will work on the rifles I care to chronograph and I'll still have my cheapo Chrony as backup. Like most other people, the setup is what's driving me to look at one of these. My range has overhead baffles so there's no enough light. Setting up the unit further out to clear the baffles makes alignment even more tedious and you can just about forget that when people are present. I don't chrono often, so I can't really justify the Labradar. I just wish the Sporter version wasn't quite so cheaply built.

LED lights for the Shooting Chrony family - LINK
Also, I recently got a Magnetospeed Sporter. Took it out for the first time this weekend. I was very pleased with the results. |

Now that I have used all three types for my own purposes, I can make a comment on what I liked the best.
All of them, sky-screen optical, infra-red optical, magnetic, and radar, all have pros and cons. I liked the Oehler 35 better than the alternatives back in the day. I still found myself using the little ProChrono on most range trips since the trouble of setting up the Oehler was much more fuss than a simple tripod mounted ProChrono. The small errors in the ProChrono were not enough to bother me and I would use the Oehler for absolute values or serious work. The Magnetospeeds were really good for accuracy, but bothersome to mount. If I put enough effort into attaching them to work around bbls, they worked fine but then you might not always be able to do accuracy work when the Magnetospeed ruins the tuning. Some guys run with one most of the time, but to do this they are creating a big cantilever mount that carries the sensor without using the bbl. This way, the bbl tuning is unaffected. I find this to be no problem with small sport bbls, but with large bbls and muzzle effects, the standard tackle they provide won't work. For pistols, they can be very tricky to mount. Now that I have run the LabRadar, there is no looking back. The reaching over to the unit to hit the arm setting after it times out is one negative, but it isn't much to program a longer arm time, or to just remember to arm if I have a long wait or delay during a shot string. Other style units don't have this issue. Our club's benches are typical designs in terms of the length of the table out by the muzzle, and you will find yourself having to sit way back to keep the LabRadar near the muzzle. It really isn't sensitive to exact muzzle position in my experience, but it does require a full size bench surface or a tripod. I have never had to ask anyone for a range break to set this up. Based on how easy the LabRadar has been to use, it comes with me on every range trip and I find myself running it all the time. I can recommend it if the price tag isn't a problem. |

Here's one example of "cheap." 16+ feet of 12v LED strip for less than $10 at Amazon. Right now, the biggest issue I have is that the diffusers that come with Shooting Chrony units don't blend the light as well as I'd like - there are still distinct bright spots where each LED is. I will have to test this approach to see if it works before I spend more money on smoothing the light better. But those "12vdc LED strips" will run off a 9v battery just fine... So at worst, (once I get the things working and properly wired), they would require a couple extra 9v batteries and some finessing of wires to get 'em to do the job. |

With just a few clouds blowing by, I missed a couple of shots. I've decided that what the Shooting Chrony needs is an inexpensive, battery powered LED light system. Just something on the diffusers to provide consistent light over both sensors. I haven't figured out how to make the diffuser properly diffuse a string of LEDs to make the light more continuous (not a bunch of bright dots), but that's the direction I'm looking. Shooting Chrony says a cheap photographer's tripod is fine for mounting their device. Sure. With a dead calm wind. It also helps if you're setting it up on a perfectly level surface. I've seen my unit wobble in the wind enough to affect the alignment of my shot over the sensors using a "cheap photographer's tripod." Next time I take it out, I'm taking photographer's sandbags too. Photography often requires weighting things like light stands and such, so there are special sandbags for this, pretty much flat rectangles that often have a seam in the middle so they drape across a light stand brace... https://static.bhphoto.com/images/images250x250/1456501515000_1161029.jpg Hang one of these on the braces on your tripod, and it'll stay put. If your chosen site for the chrony is uneven, I'd turn the tripod so that one leg is "uphill" and then hang the sandbag on the brace for that leg. Other than that, I still haven't managed to work out downloading the data from the chrony so I could look at it on a computer. There are devices to let you do this by USB connection, and I think there's even a Bluetooth project out there. But you need to have a program to querry the device to download the data, and they're available - but I don't run Windows 3.5 anymore...

Who needs the stinking lights, Labradar runs from 6 AA's. I carry a spare 6, just in case.

Labradar if you can swing it. Traditional chronographs are inaccurate if conditions aren’t perfect. The magnetospeed....forget about getting velocities and shooting groups at the same time...so double the number of rounds you load at each charge to be able to do both. I’ll be buying a labradar after using them a few times. It’s not even a fair comparison.

Love my LR, but I finally found the perfect set of conditIons in which it becomes more frustrating than an optical chrono.
Was doing some load dev on a 6.5x47L bolt gun with the well oversized 338 Titan-TI suppressor in place, which required the use of the external mic and setting the sensitivity to 1 or 2, the most sensitive of settings available. When combined with gusts of 30mph wind, it was an exercise in futility. The wind would trigger multiple false readings in a row, turning my range trip into a cardio session to crawl back and forth to delete the bad rounds and reset the unit. Still love it, but this is the one set of circumstances where it falters. |

I sent an email to the US Distributor on Sun about the Bluetooth. I got a response on Sun also, "Android is due out this month, IOS don't know when" I'm not holding my breath. It's winter and I'm reloading and not doing much shooting so don't really care.

You guys cost me more today. But not as much as usual.
I've been working on load development this winter and had the Shooting Chrony out on Sunday. I've had it since 1994 and even after all that time it's still a pain in the ass to setup and to work consistently. So after reading this thread this morning I bought a Magnetospeed Sporter, it will be here on Friday. THE main reason for me is I live in the country but it's not as country as it once was. I can't shoot at home like I could but I can step out the door and fire a few rounds once in a while into a dirt pile in my field safely to get velocity readings. The time to setup for a few shots with the Chrony took the fun out of that. Can't wait to try it out. |

I plead the 2nd.

Keep the thread updated when you've had a chance to try it out.

View Quote The Sporter arrived today, didn't get a chance to actually use it yet but a few comments so far; All the bitching I have read and heard watching video reviews about the strap not keeping tight or not being able to tighten have me wondering WTF. I can see how some might have a problem since I did at first. But if you engage the brain it's not real hard to figure out. The end of the strap with the buckle thing will slip off of the block, it just slides on. IF you adjust the strap to length to fit your barrel with the tightening nut almost off of the threads, (that would be so tight that it takes a little effort to slip the buckle back over it's holder on the block), then tighten the nut and it's tight as hell. I can tighten it so tight it starts to deform the plastic. If that comes loose after a few shots I'll be real surprised. To remove, loosen the nut until you can slip the buckle from it's holder on the block and take the unit off the barrel. If you are using it on the same diameter barrel again just reverse the above to put it on again. Tip; It's hard to get the strap tight enough to start with by trying to just pull on it. I adjusted for length with the nut near the end of it's threads and by removing the buckle from the block and tighten the strap until it was a little difficult to get the buckle to slide on to the holder while pulling the strap over the barrel. The overall "quality" look and feel could be better. It doesn't seem like I might still be using it 25 years later like the metal tank-like Chrony but I won't be here in 25 either (maybe). It's a specialty tool that fits my needs for a quick and easy way of determining velocity at home and to analyzing strings of reloads at the range. It also can download it's data to my smart phone. ($25 more for the adapter thing) So far I'm happy with it. Hopefully I'll get some powder burns on it this weekend. |
