Default magnetospeed v3 vs labradar

i haven't found a direct comparison between the two with actual data. luckily this past weekend i had the opportunity to test (very unscientifically i may add) the two of them

this was a 5 shot string with a 338 norma shooting a 300 grain berger otm

shot.....magneto.....labradar.....delta
1..........2772............2785..........13
2..........2763............2783..........20
3..........2758............2782..........24
4..........2768............2785..........17
5..........2761............2784..........23

avg......2764............2784..........19
SD.......5.6................1.3
ES.......14.................3.................11

as much as i want to believe in the labradar to make myself feel awesome, im fairly confident that my reloading practices are not at the level that would produce a 3 fps extreme spread over 5 shots. so even though i have no scientific justification, i feel that the magneto speed had the correct velocities. too bad there wasn't an oehler out there too to compare all 3 at once.

now this was an very impromptu test, so and the sample size is extremely small. so take it for what its worth. im not trying to bash on the labradar as i think it is an amazing piece of equipment that can do much more than get muzzle velocity. but i figured someone would actually want to see a shot by shot comparison.

You have to put a string of periods ....... between entries to get them to align, it doesn't accept spaces.

Have you tried the labradar on 22 caliber bullets? I haven't seen anyone have any luck reading small bullets with the labradar.

it wasn't mine, but when i saw it out there i couldn't pass up the opportunity to do a side by side. and i think the smallest caliber out there was mine with the norma. so i can't answer the question about the 22 cals

I compared my Labradar with my Kurzzeit BMC-19 and found the data to reasonably correct, no reason to doubt it in my book.

15 fps is less than .5% error not enough to worry about.

Only complaints I heard about .22 bullets was that they weren't getting consistent readings out past 50 or 100 yards. Seemed like a non-issue to me, as no other chronograph I have seen can even begin to give you velocity vs. distance readings.
Note: neither chronograph has been calibrated, so they will read slightly different. We all are sure that the clock is perfect with all chronographs, but are they?

i completely agree that 20 is a drop in the bucket percentage error wise at 2700+. the only things I've ever read is that they are "reasonably correct" and other vague terms. nothing saying it average xx difference between blah blah. I'm sure the data is out there, but i just haven't asked the right person. besides, as a numbers nerd, i much rather see quantitative data than qualitative.


as a mostly long-ish range shooter these days, the ES number is what i want to keep tight. one result says keep on doing what you are doing. the other is telling me that maybe i should spend more time at the reloading bench.

If you want precision then get a Kurzzeit BMC-19

Until you use some calibration standard then its all relative.

Each technology has some limitations and influences.


At the end of the day it only mater how the bullet prints

I have both and plan on doing a side by side comparison in the next week or so.

I would expect both the LabRadar and the Magneto to have significant margins of error as there are limitations on both. Doppler radar is an extremely good way to measure velocity, but clearly, you would not be able to get an excellent unit for only $700. It is my understanding that both systems have provided results reasonably close to an Oehler. It isn't as important to get the exact velocity as it is to know your relative spread. Exact velocities usually don't provide much value over a "close" velocity since the associated BCs for the projectiles are generally even much more flawed than the velocity measurement with these newer chronographs.

I just got my LabRadar in the mail, and I haven't used it yet. For me, the decision to get a LabRadar was an easy one since I will use it primarily to test high volume projectiles. Because many of the large cartridges come at a very high price to shoot, having a chronograph that can measure your velocity while you shoot is a huge advantage as you do not need to waste expensive ammo and expensive barrels by shooting them through a chronograph. If I was only shooting high velocity 6mm projectiles, I probably would not have gotten the LabRadar since I fear the measurement will degrade with small, fast projectiles.

I've had the Labradar for a few weeks now. Here is my take... I do not have to wait for a line break to set up a triangle unit that I've accidentally shot a couple times.... I'm pretty sure I would manage to shoot the bayonet thing off a magnitospeed and I didn't like having something on the barrel. Oh, and I can chrono all handguns! Win right there! So, ease of use is great.... battery life seems not so good, but you can use a USB phone battery, so thats not really an issue.

Also, I can use this in a indoor range. Mind you, I'm still tinkering with the trigger sensitivity and stuff when on a public range or indoor range. Now the smallest I shoot is the 6.5 now (haven't shot the 223 in a while, but playing with it in the yard, I was able to chrono my airsoft witch was cool...

Anymore experience? Any one? Trying to decide between mag speed v3 and labradar.

I don't have one, but at the range I saw a guy with one and I asked him how he knew he was aiming it properly and not at the next lane. He taped up a little metal tube into the aiming notch so it was like an aperture sight.

I tested one. Read 5.56 and 5.7 fine along with 9mm. However I wanted to use it down at the pistol range, where targets are 20-30 feet from my working area. It didn't like that. Once I brought it up to the rifle range and had considerable distance between where I was shooting, it was happy. The manual I had with the unit didn't make mention of this, but I see it's on the FAQ now.

I have both. Go Labradar no POI shifts using it. Just take a battery pack to power it,. It eats them quick .

The Margin of error is good on the Labradar. Time to set up is much faster over the Magnetospeed

My wife thinks I only have 3 guns

I have Labradar, use it for handguns though. I like the fact it is very easy to setup, and I can use an external battery pack.

What distance where you shooting your handguns from?

biggest limitation with magnetospeed is it doesn't seem to work for cast lead bullets. Maybe my bayonet was too far from the barrel, but same setup produced a result for a copper solid.

Read an article recently about that issue too. The author said he had to increase the sensitivity to register CB. Since I mainly shoot CB, the magnetospeed looks like it might be more problematic than the Labradar.

I can get my Magneto to work with cast lead in my handguns but it always seems to take some fiddling with the sensitivity setting. Different calibers seem to like different settings. Even then, it is not uncommon for me to get velocities that appear to be doubled.

It doesn't fit some semi-autos, or revolvers with less than a 4.5" barrel. Those would not be issues with the LabRadar.
