FX Radar Chronograph
« on: January 15, 2020, 01:44:51 PM »
Serious airgun builders and modifiers would be best equipped with a Labradar. With that device, all sorts of ballistic data can be garnered. But for the rest of us, a less-capable device is in order. Enter the FX Radar.

The FX unit is three inches square, and about one and a half inches thick. It runs on three AAA batteries, which last about 8 hours of continuous use. Or so I read, as I only got the unit today! I had ordered it yesterday, from Utah Airguns. Can't beat the service, now can you?

ndUtah Airguns included a barrel mount, but its usefulness is a bit questionable. It mounts on the gun, and the bracket to the FX Radar with rubber bands. Not too swift as the unit sells for $200. And, FX will not warranty the unit due to damage caused by the owner. Like shooting it!! (Don't ask me how many times I've shot my Alpha Chrony!)

Well, I was told by Utah Airguns, that the shots were between 905 and 910 FPS. Just this morning, based on those numbers, I started to miss a few things I should have hit. Well, guess what? The velocity now is hovering around 930 FPS. Now I know why I missed the shots I did.

All and all, this is a neat device. It uses a smart-phone app (iOS or Android) and BlueTooth to display the results. The app, along with its included manual, is easy to install, and set up. Like some fancier chronographs, it does the average, deviation, etc. all of us like to have.

Yes, it is a bit more costly than say your basic chronograph, but you can take this unit anywhere, and use it without a setup, save using a tripod or a few rubber bands! To me, that a win-win.

I bought my crony from Bakers then a month later they had the FX in stock. I been thinking about taking it back and trading it in for some cash off the FX unit and some cash on my end.

Be shore taking the barrel mounting bracket with the FX
Without you wont get a decent measurement out off it.

I thought so too, but the bracket in question attaches to the barrel with rubber bands. Truthfully, it isn't all that stable! I used a tripod*, and have had zero issues. In fact, mounted six inches under and behind the muzzle, it never missed once!

Incidentally, there is an after-market "clamp" which is 3D printed. Users says it is far superior to the "factory" one. It just might be, but the tripod works so well, I'll stick with it.

* The tripod I used on my shooting bench, is one of those bendable-legged ones, you often get free as a bonus from Alibaba. It is very light, and The Who;e mess can be put in pants pocket.

I have a Shooting Chrony Alpha Master Chronograph, Red. It’s got the remote display. For the most part it has always worked for me. It does mysteriously throw errors here and there, but the information it gives me is useful and has helped me tune my airguns and determine when an Airgun is losing power or having erratic behavior. It is picky about lighting and I end up only using it outside where the natural light keeps it happy.

The other week I had it assembled and sitting on my boat. I picked it up to carry it outside to test some bullets when it exploded in my hand. Well exploded might be an exaggeration, but it did fly apart and sent diffusers and steel rods flying everywhere. The rear sensor, while under tension from the rods,  let loose as the screws holding it together failed to do their job. I replaced the screws with slightly longer screws and found all the parts but one steel rod. Cut a piece off a tomato cage to take its place.

Couple days ago I dropped another rod in the same vicinity as the “explosion“,  it too disappeared. Doh! Found it under a stereo cabinet along em with the original Chrony diffuser rod. Yay!

Anyone who has big bore Airgun like a Quackenbush.58 or .458 will know that your chrony needs to be a good distance from the muzzle for a couple reasons. First reason is the air blast will give you crazy readings or errors. Second reason is the air blast will send your diffusers flying through the air. The range master at the Richmond Rod and Gun range laughed his ass off when he thought that I’d shot my chrony. Truth is it was just the air blast sending the diffusers flying. The DAQs need 10-12 feet of distance from the chrony to get accurate readings.

At the Richmond range I gave up on using the Chrony because the guy next to me was shooting a Centerfire something or the other that triggered the chrony each and every shot. I figured it out when the chrony started registering 2800 or 3500 FPS! I knew the DAQ wasn’t capable of that.

I always wondered why the Chrony folks would go to the expense of making a nice folding steel case but not accommodate the diffusers and rods for storage. Goofy design me thinks.

Oh, I shot or nicked the Chrony once. Still works fine.

I wonder if the Fx Chrono likes big bores?

The best placement is about 6 inches back, and a few inches under the barrel. Just today, however, it wasn't registering. I was using a tripod which stands on flexible legs. Once I replaced that tripod with a good one shitting on the floor, everything works as required.

BTW I provide 3d printing services. If I get one I may explore a mount for it.

Did you check the data with another chrony ?
Tripod will give data
Only with some set ups none off these make sense by off set errors.

They do.
Only the FX will not calculate any errors ocure by an off set placed unit like a Labradar will.
So for accurate measurements the FX radar has to be placed as close to the barrel as possible.
And the distance ( off set)  has to be the same all the time to get usable measurements.

I "had" the FX Radar mounted on a springy-legged tripod, sitting on the shooting bench. That seemingly was the issue. Once I used my good tripod (Sony Handicam specific), the FX did its job. One strong attribute it has, is its size. Hauling around and setting up a Labradar is a bit tedious to say the least.

And yes, the FX has to be pointed forward, but it does work well. It agrees with my Alpha Crony when I can get the darn Alpha to work in artificial light! In order to get it to work, you have to use indirect, incandescent lighting. I use the shop ceiling as a reflector of sorts, and a 500 watt shop lamp. Anything else, and it won't detect. Works outside in bright sunlight, perfectly.

The FX placement isn't that critical I find. As long as it is behind the muzzle (they tell you six inches, but twelve inches works too), it never fails. At least mine hasn't! I've had one sent to Steve, and we'll see how it reacts to big bores very soon!

As for the Labradar. You can get by with the "antenna" pointed a bit askance, and it will still be within specs. One thing it seems to have an issue with, is spiraling (nutating) pellets. It apparently reads the velocity okay, but it gives you some weird BC readings. Why that is, I can't say.

Sidelight: I suspect FX won't be the last of the pocket radar chronographs. The technology behind them, is digital electronics from the automobile industry. The NHTSA, and the EU's equivalent, have (has) mandated front and rear radar, all in the span of a few years (by 2023 as I recall). The old cellphone analog frequencies (i.e.: ≈800 MHz) are going to be used for digital data streams, so vehicles can talk to other vehicles. Space age to be sure, but we all benefit, even though it is a case of Big Brother, all over again!

I like this guy...

Informative and funny video review of the Fx Radar Chronograph. He compares readings to the Caldwell, and Labradar.  I wish he'd added a Chrony Alpha or Master to the group.

I searched for some YouTube video, but must have used the wrong search words.

I tried the FX radar on my .177 pump gun, and it worked perfectly. The Labradar doesn't, unless I remove the suppressor. That fact was alluded to on the video. Even then past about 20 yards, the Labradar won't see the velocity, which stands to reason. It is, after all, designed for powder ammo. I suspect, it could be modified a wee bit, to allow it to work well with airguns, but that isn't their market.

As Bob reported in his latest on-line tech article, the Labradar does have its uses, and for that use, it is dead-on perfect. The FX, on the other hand, is a crony (only), aimed at us airgun guys. For that purpose, it is dead-on too!

Turns out I ended up with three FX units. I have one, Steve, you have one, and the accidental duplicate is for a special purpose. Just for the record, it was Utah Airguns mistake. I did what they would do if the tables were turned, and paid for it after the fact.

I thank you again Alan! You are amazing. :)

I think the Fx Radar Chronograph might just be a game changer for the big bore guys certainly and most likely for all air gunners.  I can't wait to give it a go. It's like Christmas all over again!

I will be reporting back. Gonna try and test it on ALL my airguns.  8)
