A microphone.

Just ordered a Labradar from Brownells.  $450 shipped before active junky 4% and Visa 2% cash back.

I bought a Magnetospeed when the Labradar first came out and was hard to get.  I should have just waited..........

i dont know if it's a standard microphone or not, the discription says it's got special circuitry or something.

I just know that that when I started using it, my radar now pics up 100% of my shots with the can.

Oddly enough, I have a buddy that has a 338 Edge and it needs the kit to pick up his shots too. He has no can, no break.

It’s not necessary.

Go in to settings and set the trigger to doppler mode instead of mic. As soon as it sees the bullet in the beam path and it’s trajectory fits in line with a rifle fired from beside it, it’ll track it.

I’ve clocked all of my 300 Blk subsonics this way since I got mine. Almost all of them suppressed. Only issues arose when I wasn’t aligned correctly, which would have screwed up the track regardless.

So I am curious guys..how does the Labrador do with very high velocity rifles with big brakes moving lots of air sideways? As in a 300rum moving a 230 @3220 plus? The blast off it is pretty bad...

Best I can offer is my LR handles 338LM with a brake throwing 300gr at a bit over 2800fps with no problems at all.

There were some early reports - might have been in this forum - of LR having trouble with velocities approaching 4k, but I don't know if they were ever resolved.

Just make sure the LR is located further to the side of the brakes rifle and out of the blast zone.

You can change the offset distance so the LR knows how far from the flight path it’s generally located.

Had to do this with my SPR shooting hot 77gr loads as the LR was seeing bits of particulate matter coming out of the muzzle and registering crazy (12,000fps) velocities every once in a while.

You need to keep it out of the brake blast.  I've had good results with a braked 300 win mag keeping it as close to the barrel as possible but pulling it just over a foot behind the muzzle.

Not a 300WM, but this is what I do with my braked 6.5CM as well. No issues picking up shots with the muzzle a bit forward of the unit, I didn't even have to adjust the settings.

I tried several different ways and placed it all over and never could get a reliable reading.
Got that "kit" and it doesn't matter where I place it.

But I will say I have one of the very first ones shipped so that might play a role, maybe they changed something.

I read the manufacturer was recommending using cinder blocks between the brake and the labradar to shield it from the blast. Maybe it was a 50 they were referring to. Seems like a lot of shielding but at least the LR would stay intact.

I got out to the range today to try out the Labrador.  Thanks to all the help here I got everything working on my first shot and everything worked great.

I didn't buy the plate or a mini tripod and just figured I'd see what I could do with a normal sized stand that I used with my chrony.

If anyone is looking for an awesome storage container for the labradar I suggest getting the Apache 4800 box from harbor freight.

You can get it on sale for $45 or use a 20% off coupon and get it for $48 when it's not on sale. It's a heck of a box for less than $50.

Leaves plenty of room for a battery and cables. It has the pluckable foam squares so it's easy to customize.

Can someone who purchased the metal mounting plate be kind enough to give me some measurements and the thickness?  I have to work this weekend and I might just fire up the plasma cutter.

Also is there anything you would change on the plate?  As in bigger, thicker, longer etc.

I'd change it into a tripod.

Seriously, the plate mounting is less than optimal for a variety of reasons. If you really want to go that way, drop me a PM and I'll cut you a hell of a deal on a pretty orange one. I'm never going to use it again.

Oh, and give me a bit and I'll get the dimensions for you. Just got home but will go dig it out as soon as the family is settled in and the dog is walked.

Plate measures 11-3/4” x 11-3/4” and is .085” thick with whatever coating they have on there. Aluminum. Four rubber stick on feet on the bottom and a tripod type head smack dab in the center.

you have to aim it very carefully at the target and make sure your rounds hit the target.  Set it up on a secure bipod don't just prop it up on a wobbly bench and let it fall over.

I had this thing out last weekend and it was amazing how easy it is to use.  I went ahead and put a small straw up on top to aid in aiming.  I bought a knock off power pack and run the app off my tablet.  I used an old padded game console travel bag (similar to laptop bag) it fits perfectly and there is room for the manual, batteries, cords and small tripod.

I wish the mobile app was better. I had issues today with it staying connected, and if it disconnected I had to restart the unit or it would fail to reconnect. Never had that problem before.

I also feel like the options from the options menu should all be accessible in the app. Maybe they are and I just didn't see them, but about all I use the app for is arming and disarming.

Brownells has them for $559 but you can use the current coupon (J9M) for 10% off and free shipping.

Also, use active junky for an additional 6% cash back.

So your price now would be $504, but you'll receive $30.24 cash back for an effective price of $473.72.

I don't think you can find it cheaper than that anywhere, even on sale.

OH yeah, they did the same in NC. I bought mine before that change took effect, so my numbers are off by whatever your sales tax would be.

I like brownells a lot. I buy almost everything from them because of their no BS return policy. When you tack on their coupons and active junky they usually beat others prices too, so it's a no brainer for me. Hell I buy from them even if they're a few dollars more expensive because I trust them.

Sold a couple things and ordered one from Brownells.  I paid a little extra at Brownells but they have the "guaranteed forever" warranty on it.  I even chatted with them to verify they'd stand behind it for as long as I owned it; from what they said as long as the original owner keeps the receipt they will refund the full purchase price if anything ever breaks on it.

I've already got a camera tripod from my other chrono, do I need a USB power pack or is it just nice to have?  Any other accessories I need to look at?  I'm probably going to get the hard case from Harbor Freight (free multi-meter!!)

I use this power pack. https://www.ebay.com/itm/Fast-Charging-Waterproof-Solar-Charger-Power-Bank-500000mAh-2-USB-Battery-Pack-/153223073463?var=&hash=item23acce8eb7 You can leave it on all day using this. A USB power cable comes with the LR IIRC so you don't need to buy one. I don't like buying/changing out batteries on every trip, so it was a must have for me.

I have a short table top tripod for the bench, but a full size tripod just in front of the bench might work better if you have a long barreled rifle. I just haven't tried it yet. I'm always afraid of knocking the LR off the bench accidentally with the short tripod so close to the far edge of the bench.

Hard case is nice. I use an aluminum case from HF that only cost $20. I print out a cheat sheet with the directions in case I forget how to reprogram a setting and put it in the case too.

Wow.  22,400 mAhr.

Or for non advertising puffers 24.4 Ahr.

Has anyone measured what a Labradar actually pulls when running?

Generating GHz RF is never a very efficient process.

And for the most part you usually need to leave the Generator circuit on for it to heat up and stabilize to perform Doppler measurements.

You are comparing your speed to the speed of light.
It makes a whistle often in the audible range.

A bullet should be fast enough to be inaudible though.

If you have cordless tools, check and see if the manufacturer makes a power pack adapter.  With the M18 version I have lets me use their batteries, which are 5 amp hour at 18V.

You are measuring the frequency shift (f-fo) of the reflected signal caused by the movement of the bullet.  You don't have to measure the speed of light, as such, but you have to know its magnitude.

The Doppler formula:  f = fo *(c/(c-Vb))

The frequency shift:  (f - fo) = (c/(c-Vb))

Projectile velocity:  Vb = (1/c) - (c / (f - fo))

fo - is the frequency of the transmitted pulse
f - the measured frequency of the reflection off the bullet
c - the speed of light, speed of the transmitted pulse (3E8 m/s)
Vb - the speed of the bullet

For a 3,000 fps projectile, this would equate to a .0003% frequency shift.

30 kHz at 10 GHz
3 kHz at 1 GHz
300 Hz at 100 MHz

Does anyone know what frequency they use?
