How important is it to own chronograph if you tune your gun? And why?

I use one of them cheap china ones that a bolt on barrel type. Dont guess i ever bolt it on anymore ..lol.

Ya,. You need somthing to keep tabs on stuff / troubleshoot. You notice little inconsistent things or what pellets used give best strings , maybe seal going bad, ECT.... Its nice to like once a month run a string and compair to last months string to see if it spot on or somrhing changed for good or bad..

I think this one was like $28. Nothing fancy just does the job i need it to do.

I have the same. Is it accurate? I don't know, but it gives Me a baseline to work from. Anything else is just guessing. The little U clamp that comes with it fits perfectly onto My LDC. Rechargeable as well.

I guess ?? It's not like you got away to test or calibrate. It's with in reason of what each gun should do if working proper and shows off fps when not like a broken spring and lost 100+/- fps

Anyway mine looks good to me ..lol

If you got 2 chrony and one gun side by side. One shows 900fps the other shows 875 in a constant string what one is true ? You don't know . That's with any . Now if one was 900 and one was 780 ..lol you kinda suspect the one

With any you just take it works right at face value and trust .. all you got is it's in reason of any fps rating a gun used is supposed to be +/-

Have some Air Chrony thing setting in a hardcase with tripod for about 2 years. Not used it once. Get a rifle zeroed in with pellet on hand and go from there with plinking and pesting. When the springers started losing accuracy, it was loose screws or loose sights. Nothing needed for any of the PCPs, yet. I had a Huben K1 which was shooting hot ... just turn down the awesome wheel and good to go by sound and accuracy. I was encouraged to have the gizmo and thus I do. 🤷‍♂️ So someday, maybe I'll use it.

is the fx chrono the best one? i notice that it is pretty expensive and there are a lot of other biggger, table top chronos, what are the benetis of this £160 unit over a £49 one with the two aeriels? apart from size and convenience ? seems everthing with a fx label has a badged price mark up.

I won’t say FX is the best, because you have to pay 3x more for the best. But it is most certainly not the worst.

I love my FX. I have the original Gen1 and it works great. I love how portable it is (throw it in the range bag), and how I can attach it to the rifle and shoot all day with it. I don’t have to worry about if I am going to shoot my chrony when I move to a new target. I also don’t have it blocking my scope, so I can shoot with it all the time and not just when I’m testing ammo.
It rarely misses a shot, and if it did… I’m not sure it would really matter. The software is actually pretty nice and you get a lot of data collection there that is super useful to come back to.
If it is worth the money over a $50 or a $600 one is totally going to be your call.

Now one more thing ..

The bolt on china or at the muzzle kind are good for that , but you can't set one up say 50yards . So a " normal" type will do . Sometimes knowing your drop off at range can be helpful . Like some pellets fall off faster then others ..

Then guys like bells and whistles or can't live without blutoot ( the long range stuff like setting up at ranges Bluetooth is a convenient must . Lol)

Me a few shots at the muzzle and a known fps goal is all I require do that china does fine enough ..🥴

I have not put either of my inexpensive chronographs downrange but I don't see why I could not. Probably not at 100 yards but at 30 or 35 where I normally shoot I think it would be fine. The window for the projectile is small but I can easily keep my shots within much less than an inch which is about twice what is necessary to get a reading and avoid hitting the chronograph. I guess you'd need to use the scope to see the reading but mine do record shots too.

What I do is to shoot my guns at multiple distances and then play with a trajectory program to get it to give me the same point of impact. I treat the bc as a variable to get agreement between the program and the shooting. Then I can use the program to get a idea where my impact will be at other distances. I doubt I would have great agreement even with a bc measured on that gun with that projectile. Small errors in the distance to the target or the height of the scope over the bore will create distances and wind certainly can. With the cross calibration to the shooting results I don't feel like I need to measure the bc, I can use published numbers and then adjust it a little if that helps me calibrate.

I'm Italian and, as in many other countries, we do have power limitations not only in case of buying and owning but also in the competitions(in BR the competitions are in 7.5J,16J and 21J).
I tune my rifles(HW977, HW50S, HW30S, RTI PriestII and Pardini GPR1) but I must be below a certain power and that's the reason why I have a ProChrono DLX.
I think that with a cronograph and a ballistic app it's easier and faster to have the ranging for hunting too.
