- Is the FX True Ballistic Chronograph the best of the radar based chronographs on the market today?
How does a radar based chronograph work?
How do you use a radar based chronograph to get the best results from your shooting session?
Does @UpNorthAirGunner really have slow-motion vision?
What data can I get from a unit like this and what do I do with it?
These questions and more are answered in this first ever collaboration video from PJ and Chris.
But first...Do I need a chronograph?
If you are an airgun enthusiast, and if you ever want to use ballistic software to calculate holds at various distances, or use the LRF version of a day/night digital scope or a range finder that can calculate holds or you plan to tune an airgun...Then YES, you need a chronograph!
Second...What is Ballistic Coefficient?
Ballistic, Coefficient, or BC, is a number that physics uses to describe a projectile's ability to overcome air resistance in flight. A high BC means a pellet or slug will slow down less on its way to the target than a similar projectile with a low BC. It will also be less effected by wind. We like things with high BC's.
Chris mentions manufacturer listings of BC being "off." Part of the calculation of BC is the projectile's speed, so the BC a manufacturer lists is necessarily "average" and the true value will vary.
Third...How does the FX True Ballistic Chronograph work?
If you want to know about radar in simple terms, ask a cop. Or a retired one.
A radar-based chronograph sends out a beam at a known frequency. When a pellet passes down the beam towards the target, part of the beam is reflected back to the chrono. The frequency of the reflection is changed based on the speed of the projectile, and the radar unit calculates the speed from this data. Because the FX True Ballistic Chronograph can read speed at multiple points along the path of the pellet (or slug, or arrow or bullet) it can take the reduction in speed between point A to point B and calculate the BC based on that real world drop. It's a calculation based on a direct measurement of what your airgun is doing given it's current tune and under any given set of environmental conditions you happen to be in, not a generic value based on a typical, generic set-up
That's why the FX True Ballistic Chronograph is my go-to tool for tuning and doping my airguns. At this time it's the best piece of equipment you can get for this task. Thanks to FX for bringing us this tool!
A final note.
Companies are bringing us adapted technology that we've never had access to before. This is just one example. I HATE when something is called a game changer. It gets over-used. I think AI gets a kick-back every time someone says it. BUT-we are getting access to equipment that allows us to measure things in ways that we haven't been able to in the past. That will, or should, challenge our foundational knowledge and thinking and help us push the industry forward. It really is a great time to be an airgunner.
Thanks for having me join you in the video PJ! Great work!
Glad to have you!
This is why I'm a subscriber to both Up North Airgunner and Wisconsin Airgunners. Quality information and just enough science to validate observations. I've only just become hooked on PCP air guns... sure a huge step up from my pumpers, Daisy 880 and Sheridan of the 1980's. Technology has made what was fun as a kid even more fun as an adult (maybe my second childhood?). Thank you for sharing and contributing to our knowledgebase.
Glad to help!
Very helpful thanks, I didn’t realise you could view the BC independently shot by shot.
Hopefully FX will update the software to GA shortly 😊 thanks for your time PJ much appreciated from here in the uk
@@CarlMitchell-oy3ly glad you found it useful.
Wow
The Two Of You … Just Educated a lot of Us on Why and How To Use The Absolute Best Device Available 🐿
Awesome Class Fellas ….
Schools Out Until The NeXT Video 🐿
Good stuff guys ! LOL Beer hunting sounds like a Wisconsin thing .
Only in the evening.
Thx P.J. I bought my fx true ballistic from Utah Air couple weeks ago I have no idea how to fully use it yet but I plan on diving in deep on it so this video is a huge Blessing. Please consider showing us how to get the parameters that may be tricky to figure out
I’ll do a follow up.
thank you. great info guys. I do wonder how the device knows when a pellet is at a specific distance? How is that determined? I see a minimum distance in the manual of 15yds for BC but no max? is there a max distance?
I split a pencil at 75 yards.
what about the design of a radar unit having a hole in the middle? The radar signature is going to be a donut and I don't know what effect this has on the BC.
I don't think you could make (and I could be totally wrong) an emitter that has a hole in it. You could (I'm sure of this) make a unit with a hole to shoot through where the emitter was very close to the hole. That would cause you to have some limitation in how you set it up and if you wanted to use the unit for archery, and using a firearm would be hard due to muzzle blast made of fire.
Why if I hit a solid target at 25 yards, the FX ballistic will show velocities at 50, 75 and 100 yards ?
Yes, and that's why it would be nice if really tells you when it stops reading and when is showing results based on BC calculated and not actual readings....so I don't trust any speed showed beyond 25 yards. Even if you change your drag model, those speeds predicted will vary....sure it could be software corrected if FX wants
This is a good question and I’m glad you asked it. When they wrote the internal software they had to decide what to report under those conditions. They chose to report the predicted velocity based on the initial velocity and the calculated BC for that shot.
