Labradar users. Can you recommend this chronograph?

Does anyone have any experience using Labradar with a suppressed .22LR?
I don't have experience with suppressed, but I have with non-suppressed. The only issue with measuring .22 LR is the tracking distance is shortened, if that is important to you. You will get very accurate muzzle velocities but due to the small bullet size, tracking more than 50 yards causes poor signal to noise ratio and some funny readings.
 
This isn't 22 LR, actually 22 Cal .224 55 gr FMJ-BT with cannelure #2267 bullet. This is an example of the data you can capture:

That would be a problem for me because the Labradar units sold in the EU are restricted in terms of power setting. Can only have standard power which I understand leads to reduced detection range.

That’s not their only problem. Might have to use their “airgun adapter” ~$50 but if you order both today it will be like ordering the base unit tomorrow. Today is the last day for the $50 off promotion.

They also have an “archery adapter” that is essentially a manual start button.

I am waiting on the 2nd generation that will surely include some of the options and likely cheaper but I already have a number of chronographs too.
 
I haven't had mine that long, a week so far and 30 strings, but I can recommend it (minus the whole "how long will it hold up" ?).

I was lucky in that it arrived the same day the android app was released, so I went straight to using my tablet. I've had zero issues so far with any aspect. Yesterday we were testing loads for a friends 6.5C at 10 & 200, then went to plinking on steel at 300y. Shifting to a different target array took all of about 5 seconds. My cheap orange (matches the Labradar) carpenters square works pretty well for aiming. Yesterday we used a tripod as our rifles have 24" and 26" barrels with brakes and the bench plate on m bench won't work. The Labradar didn't miss a single shot out of about 50 rds combined. Later that afternoon I used it to chronograph my .223 while shooting steel at 400ys. This time I used the bench plate as there was plenty of room on the table to position the unit.

We shot yesterday for about 3 hrs and the USB battery pack indicated was still full. I seriously wouldn't sweat batteries WITH a USB external pack.

Accuracy is on par with my 35P, I chrono'd my standard load in both and it was within a few FPS and both have the load at single digit SD. Labradar is slightly faster, but that could be due to slightly higher temp and the 10' standoff with the 35P

The exportable "reports" are great! I've also got an Oehler 35P and the Labradar reports are head/shulders about the adding machine paper. I now have a separate spreadsheet per rifle, with tabs per load. I used the Labradar in conjunction with a Kestrel and Strelok Pro, so I'm recording on paper the series, basic cartridge data, weather off Kestrel and the typing it into the Strelok. Both the LabRadar and Strelok Apps reside on a 7" tablet that I carry in my shooting bag, so it's easy to hop back and forth.

Overall I'm impressed.
 
Mine shows up tomorrow and I ordered a Slik brand tripod yesterday. With any luck the tripod will show up by Friday so I can try her out next weekend.

I am excited. I think this is gonna be fun!

Always fun to playwright new toys.
 
I thought I'd just share quickly as it pertains to the Labradar IMO.

As I said above I ordered a Slik brand tripod, and specifically it is the 700DX. It arrived yesterday and I did a bit of fiddling around. I'm very happy with my choice. The legs are in three sections allowing a variety of different setups. The central column is adjustable, and reversible if you desire to also use it for low angle photos. It extends to 75" max height. The hinges are actually metal, and seem reasonably stout. It comes with a 3 year warranty also. You can attach a ball head to these legs also, and I may pick one up in the future. After taxes it cost me just over $150 on amazon.

What I really like is that you can set it up in the traditional way, like this.

Or you can go for a more squat setup, like this. It seems more stable and less likely to tip over if a wind kicks up. However Slik recommends the first setup to minimize vibrations.

Or, if you are out and the wind is really worse than you planned, you can set up with a super wide stance. This would be pretty hard to blow over, and if the wind is that strong, I would think you wouldn't want to be collecting data anyway.

I would also expect that if you inadvertently tripped on one of the legs, that it would crumple, as I don't think those legs are really meant to be fully extended at this angle. The directions do not prohibit it though.

All in all this setup seems very stable to me. There are leveling bubbles on the head also so you can be sure to properly set it up, and if you are like me and you shoot in the woods, the ability to adjust to uneven terrain will be a benefit. I obviously won't know for sure until I try it out while shooting.

On another note, I like where I live. While I was playing with my setup on my deck, this little one wandered through. It's been hiding out in the tall grass in my back yard since it's like 3.5 feet tall, and last night it was sitting under the stairs off my deck that go to the cellar. It looked a little surprised to see me, but it's starting to learn I'm not a threat. There were three rabbits sitting in my front lawn together yesterday too. In winter I typically have 4-10 dear bedding down in the back yard for 3 or 4 nights a week. It's like a petting zoo in my yard.

No it can't. Not practically.
The "bc" varies by velocity.
The published bc is a considered blend of different velocities. You can much more accurately model the long range trajectory by using the right bcs at different velocities.

So yeah if you want to get the absolute real bc inside 100 yards (inside your zero range) then by all means, spend $700 on a lab radar. But if you use that bc for 500 or 1000 or 1500 yards etc you will have outsmarted yourself.

Now I suppose it would be possible to place your lab radar 1500 yards down range and then shoot JUST beside it to pick up the change in velocity. But who really does that?

Or, you could download some cartridges to get BC at lower speeds. Would have to go to cast bullet load recipes to get some lower velocities, but you could fill in the curve all the way to transonic and below if desired.

Getting a BC for cast bullets is another great application, since many don't seem to be published.

Personally, I love my Labradar. Once you figure out the sensitivity setting (4 seems to work well for a centerfire rifle), you can shoot on an active range and get your data without ever having to go downrange and fiddle with an optical chrono or worry about shooting it. This alone makes it much more useable since I can just shoot what I want and get velocity data.
