Battle of the cheap AliExpress chronographs

[blackdog899]

It started when getting into Airgunning and setting up a range in cellar. My old shooting Chrony wouldn’t work inside.

First was the black one pictured $ 27 . Clamp on muzzle ( high tech rubber bands best ) set to fps and shoot. Has worked very well . Only complaint is reading only lasts for 2 seconds. Rechargeable

Today 2 more arrived and I just tested.
The small aluminum one has a really weird attachment apparatus. It does all the fps, energy, recording etc if you want to figure it out. I rubber banded this on also and it works. For me I want to see the display and you can’t from your seat without leaning way out. Rechargeable.
oh yeah $18

the last is a more conventional and works same as a Shooting Chrony. Best thing for me is it has leds and works inside.
$33 batteries

I have the 1st and 3rd one. I like the 3rd the best. I got it to work in the app over WiFi, won’t work with iOS so you need an android. The problem is iOS will disconnect automatically if there is not “data” connection. Once using it in android I wast able to copy/paste the data. It will suddenly disappear also, oh and it only tracks 20 shots. It will purge the oldest. I found the app data useless, just use pen and paper or like I do and open excel on an iPad and use a Bluetooth number pad to quickly record.

I have the original labradar and the new LX, and I still find these cheap chronographs very useful for tuning a rifle. I’ve tested them against each other. The velocity might be off by as much as 30fps, but shot to shot they have consistently mirrored each other. So if one shot on the lab is 5fps slower than another he previous shot, the Chinese will also record 5 fps slower

Didn’t know about Wi-Fi. It’s also the one I now use. Did go outside and used the black one for ease of setup.
don’t think I’ll ever use the second one . It does work though and provides all the info . I mean $18 for someone that doesn’t want to spend more .
