LabRadar vs. professional Weibel Doppler Radar benchmark test

I haven’t bought my own LabRadar yet, but I’m seriously tempted. I am shamelessly using my friend’s LabRadar, with all options, for chronographing my ammunition. And he has to carry it too!

As if our firearms themselves weren’t enough, the McLaren orange radar always attracts other shooters at the range. A constant question is how accurate it is versus other – more traditional – chronographs.

Well, what do you say? How accurate is accurate when you really don’t know? It may seem accurate to use, but do we really know? At least we have some sort of “constant” to rely on, which seems reliable enough.

We have even setup 3 chronos in a row to try to measure what’s going on. But then the bullet loses speed as it travels, so you wouldn’t get the same speed anyway. *sigh*

All in all, the LabRadar is a very nice product. We had very little problems with it, and it has given us a lot of answers (at least what we think are answers) to why we hit low or high. We even sent back batches of ammunition to a supplier as the batch-to-batch results were nothing but a joke.

The only issue can be for the LabRadar to find the bullet sometimes, so you have to move it around a bit. This is a source of irritation, but a minor one. At least you never have to be afraid of hitting your LabRadar chronograph with a low bullet, although I’m sure someone succeeded in that too.

FinnAccuracy had the opportunity to test the LabRadar against a Danish Weibel doppler radar. I am not sure exactly which model they used (if you can identify the model on the picture, please write in the comments), but we’re talking about an extremely expensive unit for expert users like the military or commercial ammunition developers.

You can find out more about the LabRadar here: Discover the new generation of Ballistic Velocity Radar.

The rifle was a Sako TRG-42 in .338 Lapua Magnum, with an almost brand new barrel, still in break-in phase.

The ammunition: Lapua B408 Lock Base, factory load.

The powder temperature was +25,5C or 77,9F.

Measured difference equals average 1 yard flight distance deceleration in first 10 yards range from the muzzle.

As you can see the LabRadar measurements are very close to the high-end system by Weibel.

Considering the LabRadar is about 560 USD I’m very impressed by its performance.

    A most excellent article. Thanks. I have been watching the Lab Radar since maybe as much as two year before they actually started shipping them. Unfortunately, I am one of those that prefer wait for the Mk 2 to come out so that you can get one with the bugs worked out. This is turning out to be a long anxious wait.
