Muzzle speed Meter with tripod $28.92 @ AliExpress

[Madd Hatter]

Anybody shoot theirs yet ? Kids took my  charging cord CAN'T find it anywhere ! Anyone willing to surrender their charging cord ?

Have you gotten a cord yet?? I just killed mine, it only took 6 shots to kill it. lol If not PM me your addy and I'll send it out to ya.

I had a credit for $29.97, so it cost me $0.67.

You feel like you overpaid?      

I got one too (from Chicago) but paid more and got it in 4 days off eBay. I printed a narrow MPS to FPS conversion strip and taped it to the top.

I think the best way not to any shoot a Chrono is to not multitask,  with these small ones especially.

Here is a pic

I ordered the Clamp On unit June 16th and if the USPS doesn't screw it up it should be here either today or tomorrow. Less than two weeks from the time I ordered, not bad in my opinion.
Thanks to everyone that's contributed to this thread. A special thanks to Dan and Adam for the conversion charts.

Here is a pic, mine is not the clamp on one it has the tiny tri-pod.

My $22 clamp on model is more accurate than my Caldwell.
My Caldwell gives inconsistent velocities.  Sometimes too high and sometimes too low.

I have nothing to compare my clamp on "velocity meter" to, but it does work flawlessly and because it is clamped to the barrel I know that the pellet is going over the sensors consistently.

As I understand it, having never owned one, the Caldwell and other similar chronos, can be off depending on MANY factors.   Lighting source, angle of the shot across the sensors, etc.

For what I bought mine for, tuning AG's, it was the best and cheapest solution!   Also, I am glad I bought the clamp on model.   Much more consistent shot placement and I will never shoot and destroy it with a pellet!

I ordered my clamp-on unit on 6/18 from Aliexpress, forgot all about it, and it arrived today 7/8.  I haven't had a chance to try it out other than turning it on.

As with many others, mine came no instructions, Chinese or otherwise, so Doug's translated instructions will come in handy.  Thanks Doug!

Can anyone post the photos from the clamp-on instructions?  I just want to see what the proper mounting is supposed to be.

[Back_Roads]

 I have the clamp on model, I set it right at the edge of the barrel, end of the barrel is about an inch from the sensors. I have mounted it upside down and sideways depending on the gun I am mounting it too.

Some of us have put plastic or silicon tubing over the u-bolts to prevent damage to our airgun.

[Walther]

I also have the clamp on model, I put tubing over the U bar that fits air strippers etc and neoprene gasket rubber over the barrel cradle so it does not scratch anything.
I'm ver happy with it , found a good app for converting m's to fps but getting used to m/s  in end.
Charge seems to last a long time. I like how small it is .

Just bringing this back to the top to share a couple of observations.

I ordered one of the clamp-on versions a couple of weeks ago and it came in today.  I have a Pro Chrono that I like but as a dad with a houseful of kids, a lot of my discretionary time is after dark so it's not unusual for me to be chrony testing into the middle of the night.  A couple of hockey puck LED lights for the Pro Chrono has been the answer...it's quick and it works but it's not as forgiving as natural light so I do get some read errors.  It's a mild annoyance when it happens...unless I'm checking a rifle for regulator creep and the first shot doesn't register.  And unfortunately a string of expletives does nothing to retroactively change the result.  So I'm pleased as punch this clamp-on meter can just be attached to the muzzle and completely sidestep the need for lighting and I don't have to worry about aiming over the sensors.  It just works.

I did set up the Pro Chrono tonight just to compare the readings.  They agree very closely.  The clamp-on meter registers consistently about 5fps faster for the ~900fps test rifle, and it should measure slightly faster due to its proximity so that's a good sign.

Money well spent.  I should have gotten one sooner.

I have been tickled with my clamp-on model.   I do believe it is fairly accurate and not having to worry about lights makes it extremely handy for indoor and night shooting.

Glad to hear that it is very close to a regular crono. I need to get one of those for spot checking velocity.

Robert, I think the only problem I have read about them is from people who ordered the tripod model and ended up shooting theirs.

That can't happen with the clamp-on model.

Sure Kerry, rub it in!!!! It did take 6 shots to kill it though. lol If I shot to close on the tripod model the readings were all over the place. Maybe because the clamp on model only has one light and sensor front and rear it's not affected by the air being expelled with the pellet.

LOL!

Honestly, I could not remember who posted about shooting their tripod model.

All I know is that I am still very happy with my $31 clamp-on model.   It does everything I need it to do.   If they ever come out with a model that does FPS instead of MPS, I will probably buy one of those in the clamp-on style as well.

I have shot both of my tripod models more than once - luckily they were just barely grazed every time.  Both still work very well, but the casing is a bit cracked up on them.

The only problem that wasn't my fault was the tripod itself breaking on one of them.  The tripods are flimsy, but I don't really need the tripod anyway.

All in all these things are great for the money - they almost never fail to register a shot.

May I ask why you bought the tripod model instead of the clamp-on model?   I am just curious?

Thanks!

[Madd Hatter]

I bought the tripod model because it was easier to use imo.
