If anyone is familiar with Chrono Connect Mobile App on an android, can you give me some help or advice?
I have set it up exactly the way it shows and have fired some pellets. To me it looks like Chrono Connect it is working but it only registers 266, 263, 266, 261, 262 and so on. Like my gun is shooting consistent but the reading from the APP are low. It is like I have to X3 the numbers. Like it doesn't know yards from feet. I am shooting a Crosman NP .22 and 13.43 JSB's so I know I should be getting almost 740+ FPS.
For some reason Chrono keeps my FPS down in the high 200's.
Are my settings all jacked up???

I don't know the app, but could you have it set on meters instead of feet?
-
Just double check your measurements and the actual input. It only works when you take extra time to double check the info.
-
Wish I could help "sorry" I looked at the app a little while back and it had a lot of negative reviews so I didn't download it. I really hope you get it working, I'd love to down load it myself if it'd work........... Has anyone else had any success with it? I desperately need a chrony......
-
I just started using it and it seems to be working quite well,
I don't own a crony to test it against but here is two strings I got
from my regulated Daystate according to the factory it was shooting
848 fps with 10.65gr pellets for 17fpe http://www.daystate.com/cgi-bin/dbspace.cgi (http://www.daystate.com/cgi-bin/dbspace.cgi)
here is what I got with crosman 7.9 pointed pellets:
String 1 string broken-down
1.786 A B
2.852 786 852
3.788 788 858
4.786 786 859
5.858 787 854
6.859 787 855
7.854 786 845
8.855 786 850
9.787 786
10.787 782
11.786 782
12.786
13.786
14.845
15.850
16.786
17.782 If I only count the shots above 800fps as reading right here is what I got:
18.782 average fps:853 = 12.77 fpe ex spread 12fps , 1.7% extreme spread
now when I first saw this string I wasn't very happy
except that it was consistent
But afterwards I figured out part of the problem
I was shooting out a window with the barrel
about even to the inside ledge... ::)
Also there was a lot of background noise when I was shooting
(pneumatic impact wrench on and off)
Also keep in mind both strings were shot
in 5 degrees F weather so the gun
was cooling as I was shooting...
When I tried it with the barrel
2 inches threw the window this is what I got
String 2 with 7.9gr .177 pellets
1.824
2.919 String broken down
3.911 A B(errors)
4.911 919 824
5.845 911 845
6.923 911 824
7.912 923 824
8.910 912
9.899 910
10.824 899...
11.824 910
12.910 910
13.910 910
14.910 911
15.904 910
16.911 910
17.910 915
18.910 912
19.915 908
20.912 903
21.908 916
22.903 909
23.916
24.909
Which gives a avg of 910.6 fps
avg 14.5 fpe
inside of a 2.6% spread
High of 919fps low of 899fps
So its seems to work quite well if
all you measurements are right(down to roughly an inch or two)
(I've read LDC's and shrouds can mess with reading?)
You can also try adjusting the sound sensitivity
or try using the "gun specific options and see if those help.
So far I'm happy...a free crony 8)
I'm also planning on buying the upgraded version
that can keep shot strings so I don't have to go check the phone very shot...
?Hope that helps?

I used it on android and had good luck with it. I'd double-check the settings as someone mentioned but also be sure you are shooting at something that makes a loud noise. I used it indoors and shot at an empty can hanging in my pellet trap. Don't use a LDC either when using it.
-
Well, thanks guys for all the responses!!!
@ Farmerjoe
Your answer probably picked out my chrony errors the best and probably hit the nail on the head!!!
I have been standing in my garage and shooting into the backyard...I have been shooting at 36ft exactly...and I know all my measurements are correct because I have a 30' tape measure I'm using to mark the distances down. I am also using "Feet" as my "Unit of Measure" and not yards...because I want to be perfect in my distances.
Here is the kicker. I shoot into the backyard through the side door (man door) that is about a 2-3ft distance in front of the muzzle. I know the sound is picked up by the phone from the target because I hung an 1/8" steel plate that i hit that makes a terrible racket when struck!!!
The Chrony must be picking up the echo or reverb from the shot cycle coming out of the door and for some reason it really slows down the readings...not sure how...but it sounds as though your window was doing the same thing.
I will try it tonight with the muzzle past the door!!! By the way, my rifle has a sound suppressor...it is a Stoeger ATAC...like the Stoeger X20. Hope this is not an issue as well.
Thanks guys...at least this is a start!!!

Hoping to learn how to use this from your post Zulu, I downloaded the free version to my android phone, Samsung Galaxy S5 Sport. Can you access the settings needing changed on the free version? I couldn'd figure out how to access any settings? Surely it'd need to know the target distance and what not. If it'll work I don't mind buying the pro version, butt.......
-
Hope it works Zulu! Sounds like your shooting area is almost identical to mine ;)
Its the only way I'll shoot in this cold/wind
(even though its not heated it get you out of the wind...)

does you phone have like a menu(not home) button on the left bottom of it?
on my android it has four bottoms
on the phone and if I hit the one on the far left
it brings up the menu for picking the settings
(hope that makes sense?)
Or look for 3 horizontal bars?
And yes it will need you to put in the three distances and the weight and B.C. of your pellet.
Both of my string were shot with the free version.
only downside is I can't see is I can't see the phone in my set-up
so every shot I have to get up and go outside to read it and write it down...
(that's why I'm looking at the pro version)

No such luck for me I can't figure out to acces the settings at all.

Try long pressing the button to the left of the home button. I just installed it and that is how my S5 works.

Mobilehomer "YOU DA MAN!!!!!!!! that did it

I posted the way I had it set up in a thread somewhere and if I can find it, I'll post a link. You could also just run a forum search for chrono connect too.

I did try the search...but most of them I ready were not per my question. Meaning...I knew the phone and Chrono Connect were working...but couldn't understand why my reading were so accurate but a 1/3 delta away from what they were supposed to be.
In my mind I was getting accurate readings...just all super low...but still accurate...
Before I ask any question i always do a search 1st...i have learned that from years of "forums" experience...hee hee hee
On my way home from work...give me about 2 hours from now and I will have ran more tests!!! I'll post here when done.

Those were my thoughts exactly when I first used it :)

Hotrod, as an aside, I have found that any app that doesn't have a visible menu button or dropdown that this the way to display it.
-
Thanks Mobilehomer I won't forget that anytime soon. LOL
Thanks Zulu for posting this. I was desperately needing a chronograph. I got home and got it set up and it worked pretty good. I had used a friends chrono a couple weeks ago and checked my rifle. The same rifle and tin of pellets was hitting just 10 fps slower on chrono connect. The weather could even cause that.......... This just might work pretty good if properly set up and a consistent environment.
-
Okay guys...not good. It has to be the environment that I am shooting in.
1. I got home, re-measured everything to a T...it is perfect.
2. double checked my pellet data..it is spot on
3. Stuck the barrel outside the door frame and fired.
4. Hit the steel plate hard and made a resounding Tongggggg!!!!
my readings
1st 322
2nd 316
3rd 320
4th 319
5th 320
6th 317
I stopped after this...pretty frustrated...I used my sons Titan GP this time (no suppressor). A rifle that 1000's of people have chronied...so I know it shoots Crosman Premier 14.3's in the 660-680FPS range.
I am going to my local range to meet up with my airgun club...one of the gentlemen there is going to let me use his "real" chrony for the day. It's an outdoor range...so I will take my phone with me and set it up and take my steel plate with me.
I will report back after I am done...the place is out in the open and NOT confined like my back yard. Shooting in my backyard is like shooting down a tunnel or an alley way. I got a house right next to mine that defines my backyard space...so walls to the left and to the right...almost like an indoor shooting range. We will see if the Chrono Connect Mobile hates confined spaces or not.
Wait for report on Saturday

Bummer...try taking along a plywood or hard wood
piece of wood as well, that is what I've been using
not sure if it would make a difference?
As a side note my Daystate has the factory LDC on it.

That's a bummer Zulu. I can only speak to what worked for me, but I was indoors, shooting a can hanging from a string 26' away with the phone exactly halfway between them at 13'. Maybe it just doesn't work as well outdoors because it measures sound and the time between the 2 loud noises. If you can, try it indoors and/or maybe shorten the distance so it picks up the right sounds better.
-
What are you measurements?
One thing you might already know they recommend having the target 10-20yds from the shooter.
Here are my measurements:
"Muzzle To Target (A)"
513 inches = 42.75ft
"Device to Muzzle (B)"
27 inches
"Device to Pellet Path (C)"
35 inches
Hope you can get it working.

Zulu, It must be your enviroment. Good Luck when you can get to the range. I live out in the country, meaning nothing around me at all. I set up in my driveway at 20 yards and used a steel plate 1/8" x 10" x 10" like yourself. I put the phone 1 yard out from the muzzle and 1 yard to the side everything measured precisely out like you did. I didn't have much time to test but it seemed to work pretty well. It matched cross referencing chairguns predicted tragectories using two different rifles and calibers that I know the tragectories on. I certainly hope that you can get it to work out for you........... Thank You

I'll try again tonight at the house before I hit the range on Saturday. I'll try to set it up again and this time will put the phone right down the middle.
Here are my measurements...and it is all the room i got...backyard is small and in the city!!!
A = Distance from muzzle to target 30' or 10 yards. Measured it exact!
B = 24' and 6' (2 numbers here because I tried the phone close to target and tried it closer to muzzle...both were a no go.
C = 16" I shoot sitting down and using a bipod like when i shoot HFT...so muzzle is about 3 feet off the ground and I got the phone on a bucket about a 16" off the ground. Phone is off to the side...do not want to risk a hitting my $400.00 S4 and my wife ending my shooting career!!!
So tonight I will switch from a steal plate to a wood target so the sound is more of a Smack!!! than a Tonggggg! I will put phone in the middle (off to the side) and see if I can get a different result. My phone is monitoring at (41,000 Mhz) according to what Chrono says.
I also know my pellet data is correct...as well. I am using cheap Crosman 14.3 and not my good JSB's to run these experiments.
The reason for all this trouble is that I need chrony data to input my guns power specs into Chairgun...so I can then get a Mildot chart output...that I can then use to write onto my scope for HFT matches.
Need to know the power of my weapon shooting 14.66 H&N's, 15.89 JSB's and 18.13 JSB's....I even want 21.14 H&N numbers.
Zulu
EDIT: Ughhhh just found out that our range is going to be close due to rain...never had such a hard time finding a place to shoot in all my life!!! I got to drive 2.5 hours just to go shoot a pellet gun??? WOW!!!

I used it before I bought a regular chrono.
I found some tricks to help it work.
I paid for the full app.it was worth it.
On a phone, the microphone is optimized for being close to your mouth (the sound source)
I found my best results were when I used a set of earbuds with a lapel mic built in.
They are more sensitive.
I used a competition electronics chrono from a friend to compare it to.
I use iPhones and iPads, so my is somewhat different than the android.
Also, not good using it inside.
The echos drive it nuts..
It would read most of my guns well, but the ones with a TKO on it would not register, they were just too quiet.
I still use it sometimes because it is quicker to lay my iPad on a small end table we keep on the back porch, and shoot across it.
Where The table legs need to sit, I marked with paint on the back patio, so I could put the small table back in the same place every time, and my target stays in the same place. 10 meters away.
In using the chrono to calibrate it, I found it needed to be set just a little different than the exact measurements.
It needed the measurements set to 35 ft, not 33 to get the same reading as the chrono.
Your mileage may vary..
Biggest suggestions I can offer.
1 use a lapel mic.
2 either use it outside, or in a big room with carpeting to reduce echoes.
You may not here it, but the microphone hears the pressure wave..
I really like the app, I wish they would make it read from regular chrony's.
I now have the caldwell, it connects to the iPhone or iPad, but I like the interface and features on the chrono connect app better than the caldwell app.
