Odd FX Chrono problem

[cavedweller]

I set up my FX Chrono today and noticed it would only read 3 of the 6 guns I tried getting readings on.
Checked my set up several times, light was fine, position was good etc but it just didn’t see or report 3 of the guns shot strings.
Thoughts?
If I switched guns / shot one of the other 3 it recorded without fail.

Mine gets weird if I'm right on the edge limit of the velocity settings. Sometimes it helps to go up or down one velocity profile. Also, low batteries seem to make things weird.

I think sometimes results are funny some days. Try restarting phone and app. Silencers are different? Seems odd some days also. But lately it’s been fine. See how it works this week got a impact to reseal up and tune. Batteries are a must.

How are you setting up the chrono? I attach mine, near the muzzle, on the barrel. I use the chrono primarily on an FX Dreamline Tac with a Donny Fl moderator. It's a tad finicky about placement on the barrel. An inch one way or the other can make a difference. I usually place mine a little over an inch back from the muzzle. Mine will sometimes quits in the middle of a string. When that happens, I close the app and restart it. That seems to solve most of the problems.

What guns are you have problems with?

Mine started to be intermittent and had to have the transmitter replaced. $200.00 out of warranty.

As a fan of multi-step setup processes and trial-and-error and other complex, time-consuming rituals, I really enjoy the challenge of tricking a chronograph into giving me consistent and reliable readings.

LOL! How can you trust a chronograph that you have to "trick" into giving consistently accurate results? Or consistent results period? (chuckle)

Exactly.

Elsewhere from Mike:

The FX chrono is the cause of the single biggest customer service issue I have to deal with by far. Anytime I get somebody telling me one of my guns won’t hold a decent velocity spread I find out they are using the fx chrono.

We are playing the role of paying beta testers.

Exactly.

I am so glad that I found these:

Usually less than $40, accurate, consistent, can be used in total darkness. The only negative is that the muzzle mounted version only gives mps (meters per second) readings. But I still recommend the muzzle mounted version.

They are accurate, consistent, can be used in total darkness. Had mine for over 3 years. Never has failed me.

Never has NOT given an accurate reading. Let alone not given a reading at all.

No, you won't be able to get POI readings to caculate BC, but for MOST airgun shooters, this is all that is needed!

Do I recommend it? LOL!

Well... HELL YES!

 

[BackStop]

Exactly.

I think you mean "unpaid" beta testers... Right?

Yes, but not just unpaid. We pay them.

It's a rather undignified arrangement.

Agreed! (heavy sigh)

Try deleting program from phone/tablet and reinstall. Had the same problem and now solved.

Thank you for the variety of inputs - I’m going to tweak some things and try again this weekend - like completing a string on one gun, shutting everything down and starting a new string with new settings and repeating

I have found that the FX chrono doesn't like echo, from close walls or objects the sound can bounce, like in dense populated garage

Noted and I would be guilty as charged

Shooting yesterday my FX chrono coughed out strange numbers.
So. I was shooting 13 grain slugs around 1050 FPS, but a few times it would say 2 speeds for 1 shot, and other times a speed would be called out but like 6XX FPS about half of the actual speed.
And i was shooting 70 - 80 M so if it was that much slower it would not have been on the paper, or as they where bang on the 2" shoot and see targets i was shooting at.
Also i was using single shot tray, so plenty of time between shots.

I am interested in buying a new small easy to use chrono,,,,,, do not link to things i need to bolt to my rifle.

Best chrony for the money is the pro chrony dlx from competition electronics hands down with 40 years making chronys made in no speed limitations 2 years warranty! Have a Fx chrony what a piece of sh$t don’t want to read have the time! Been back to Fx once already and they said I need to use lithium batteries for it to read correctly really! called the other day told them I’m ready to set the Fx chrony out to for target practice! they are sending me out a new one since it been back once! Use to work fine last year when I first bought it here is a link of a YouTuber doing a video on chronographs
Chronys which one#competitionelectonics #fx #fxairguns #fxusa #fxsweden

 

[Wackamole]

They are definitely finicky chronographs I half to restart my phone all the time. But they are still very compact

+1 @bigHUN
Was one of the first things I thought of while reading through this post.
