LabRadar Chrono - Multiple LabRadar users on the firing line at once?

[LenBackus]

On another forum thread or topic I saw a question (which I can't seem to find again) about "what happens when more than one LabRadar user is on the firing line? Will my own LabRadar unit be triggered by my neighbor's firing?".

WHAT HAPPENS IF THERE ARE MULTIPLE LABRADAR USERS ON THE FIRING LINE?

In the Youtube video below, there is a demonstration of the various "settings" for the unit. Two of the settings relate to handling this situation.

1) Trigger Level (sensitivity)

2) Transmit Channel (frequency)

My understanding from the video is that you would set both appropriately and the Transmit Channel is probably most important.

Yeah, Yeah yeah... watching LabRadar videos it's a lot like watching Star Wars. It looks great but it ain't real. Show me one guy that has one.

My question is what about multiple SHOOTERS (within a few benches)?

 

[mshelton]

Or one shooter, no bench but multiple rifles?

My question is what about multiple SHOOTERS (within a few benches)?

Apparently, if the several shooters are on different frequency settings there will be no conflict.

If the guy next to me fires his rifle, will my Labradar pick up his shot?

 

[LenBackus]

If the guy next to me fires his rifle, will my Labradar pick up his shot?

I understand the "trigger level" setting precludes that.

 

[CPorter]

The way I read the instructions you can set a sensitivity level but the minimum is still somewhere around 2-4 feet from the center. I think it is highly likely that it will pickup the bench next to you but until one actually shows up no one knows.

Just how close does the (shot) have to be to "Trigger" the Lab Radar unit ? 1' 2' 3' 4' 6' ?

I for one like the ability to (supposedly) get the velocity at the muzzle and at the 100 yd mark .
I will be happy if this turns out to be the case.

Here is a comment from LabRadar about proximity issues.

Thanks for the question.

The LabRadar accuracy will not be affected by other shots being fired into your radar beam. Part of the technology built into the system allows it to determine if the shot came from very near the radar unit or if it came in from another location. Since the radar beam is only active for a fraction of a second it is nearly impossible for you to receive a velocity from another shooter nearby.

This is what I'm trying to get at... HOW NEAR the shots can be before TRIGGERING the unit. Near and Close are irrelative, Numbers please. Len I know this isn't your baby but you seem to have good contact with the manufacturer.

Here is an answer I received by email a few minutes ago:

Len,

That’s a good question but since each caliber, barrel length, etc provide a different muzzle blast there is no definitive answer.

It's important to remember that it is not necessarily the "sound" that we hear, but the sound/pressure that impacts the side of the unit where the microphone is enclosed that triggers the recording of the event.

For example, If you have it set on 1 (most sensitive) and you are shooting a 22LR you should be about 6 inches away for the unit. If someone is five feet away to your left or right and shooting a 223, etc you should be okay. If the 223 is triggering your unit adjust yours to 2 or 3 and that should stop the problem. When testing with 223, 270, 308, 45, 9mm 22 LR, 357 mag, 40 S&W I could not get it trigger any farther than about five feet at the most sensitive setting.

A few examples are

9mm would trigger at 12 inches when set at 3, but would not trigger at 18 inches

44 Magnum would trigger at 24 inches when set at 5, but would not trigger at 36 inches

223 would trigger at 24 inches when set at 2, but would not trigger at 36 inches

270 Win would trigger at 24 inches when set at 4, but would not trigger at 36 inches

I think there will few, if any problems with this. With settings of 1-5 you should be able to tune out your neighbor and still record your shots. If you are shooting a 22 LR and your neighbor is shooting a small cannon, you may need to adjust to a higher number. If you were shooting at level 1 and 6 inches away, you may need to move your muzzle closer to the side of the unit to get it to trigger. Even then the neighbor has to be really close. I haven't seen many cases were the muzzles were closer than 5 feet away from each other.

I hope this answers your question.

Best regards,

Thank You Len, it does help. Roger T

 

[LenBackus]

Roger, glad to help.

And I needed to know the answer myself anyway.

Aloha Len,

After reading the email it states its not really the sound that we hear that activates the unit, but rather the sound/pressure that hits the side of the unit. This may have been asked but I'm thinking a muzzlebrake may be an issue with this. Especially one with only side ports like a QD brake and similar, Any thoughts?

Thanks!

 

[suberjc]

I love good gear but truthfully I just sort of want to know generally how fast the bullet is going. It's probably all relative shot to shot anyway and my (non-scientific) findings suggest that the best chance for consistency is to use the same chrono all the time - once you've determined that yours isn't schizophrenic - or are at least able to identify it's episodes. LOL

I had already asked this question myself and their answer was as follows:

only on the BIG bore, 338, 50 BMG,

Here is what we have been telling people.

It will work with your muzzle brake on it, but if it has a very heavy muzzle blast such as a 338, 50 BMG, you must protect the unit from the blast. In that case we suggest a barrier of some type. If you are laying prone, use some sand bags. if you are shooting off a bench place the radar underneath the bench. You can experiment also by placing the muzzle farther to either side (up to 18"). Moving the muzzle forward of the unit or slightly behind may also help. The main thing is to protect the unit from being rocked by the blast.

LabRadar just told us they are shipping our first unit late next week.

We'll be evaluating it in the field and posting a quick review right afterwards.

Pre-order at the LRH Store. Pay now or when we notify you that your unit is about to ship.

When doing your testing can you also test using a silencer?
