Thread: LabRadar

How are these things meant to be set up? They used one at the chrono station for the ipsc nationals and the readings on the open guns were all over the fucking show! By as much as 200 fps. There are a few unhappy shooters who have been declared as shooting minor power factor now because of one or 2 realy erratic readings.

Whoever was running it may have screwed up or velocities shooters thought they had are way off.

The labradar is simple and accurate. It doesn't lie. All my rifle velocities are within a few fps to when I had a V3.
Pistol velocities are where load data say they should be.

But you can get inconsistent velocity readings if you do not input the correct projectile weight and that's assuming they had it in handgun mode in the first place.

Theres no way they were off by as much as the machine said. I have no doubt that the labradar is the bees knees, i just think it may have been set up wrong? It was failing to read alot of shots too. The guy was basicaly standing behind the radar and it was about a foot to his left pointing down range. I hvnt heard of any other divisions having issues so we are all assuming the comp on the open guns are putting it off. There was a roof over the shooter as well, not sure if that makes a difference.

I got a reading of 1400fps, 1415, 1250, and 1340 and a bunch of shots that didnt register. This was a common theme with all the open guys. I know that 10 grains of 3n38 should put me at that 1400+ mark so it read correctly and then had major swings in velocity. I feel for the guys that came in with a 159.? power factor, there were a couple in my squad alone.

I would say your right. Someone has mentioned in this thread about the radar not working properly with a brake until he shifted it.

I haven't used a brake over mine so don't know what can go wrong.

It is activated by sound so possibly the roof combined with the brake is giving erroneous feedback effecting the readings.
Especially when you say only open shooters are having issues.

The should reshoot it for all you open guys under a different setup.
You would think they would notice there is an issue and try and sort it?

I think it is great they are using a labradar for velocity testing but maybe they shouldn't have used one until they are very familiar with it and also have a backup optical chrony to confirm irregular results.
It is screwing up the competition for people after all.
