Muzzle speed Meter with tripod $28.92 @ AliExpress

[Fate]

I got another of the little chronys... for two reasons. I couldn't imagine being without it for one. I also wanted to see if the one I had was accurate, although everything I've read where they've been compared to fancier ones indicated they were, or close enough to be within the margin of error.

The second one is the same as the first. They're interchangeable. I use both during my shooting sessions and see no disparity in results.

In the literature for them they include a warning, however, about what may affect the accuracy of the results... like vapor from residue in the gun, or smoke from a PB gun. If your air gun has any residual oils in it it will produce such vapor in the air blast and could affect the resulting readout. If I were in doubt I'd, very carefully, set up the chrony and gun and fire it from a foot or two away.

I bought one a few weeks ago. Fantastic value for $30!

I got one of these and it came in. Lot smaller than I thought. Though perfect for muzzle mounting.

I was surprised it was right on with my pro chrony.

I did pop the top off hoping there would be some kind of easy hack to switch from m to f, but couldn’t see anything obvious. (Like the Yong Heng thermometer from c to f).

In my opinion, money well spent.

I shot my 22 Varmint over my Magneto V-3 and then shot over my muzzle speed meter,
keeping everything the same and the readings between the 2 only varied 5-6 fps,
so I do believe that this little muzzle meter is as accurate as my V-3..................

Muzzle mounted mine sideways so I can use my scope to hit my targets. My F1 chrony & Xcortech chrony are now gathering dust. NO complaint paying $3.49 at eBay with the HAPPY25 code.👍🏽

Curious to know if anyone has tried one of these clamped securely to the barrel of a break barrel.
Especially on one with a strong recoil.

My concern is that a Walther Parrus or Benjamin Mayhem 22 might lead to its untimely demise.

Thanks

 I have used mine on several break barrels, and .50 cal  big bore, it still works great.

Mine is the kind to clamp.  Nevertheless, I just rest the muzzle over the open clamps.

Just received mine after seeing all these positive experiences, and did quick a test comparing the cheap-o chrony to my F-1, using an airsoft rifle firing 0.25g BBs, 5 shots each:

F-1 (feet per second) 402.7, 396.5, 400.4, 399.7, 398.6 - average 399.6 fps / 121.8 ms

Cheap-o Chrony (meters per second) 121, 121, 121, 120, 121 - average 120.8 ms / 396.3 fps

Looking very promising, and unlike the F-1 it doesn't care about fluorescent lighting!

Naturally you're getting readings to the nearest meter while the F-1 is giving you the nearest 0.03 meters so there is a bigger margin of error but quite impressed so far.

Tried it with something more serious and got some weird results.

FX Streamline 0.22" with 200 bar fill and JSB Jumbo Heavy 18.13 grain pellets.

Power Level II - 210, 210, 213, 211, 211 - average 211

Power Level III - 204, 207, 207, 205, 208 - average 206

This gives and average of 692 fps / 19 ft lbs for the medium power setting and 676 fps / 18 ft lbs for the high power setting.

I haven't compared it to another chrony yet but something is definitely off, fired into the same piece of plywood the base of the pellet is about 4mm from the surface at medium power and 8mm at high power, so it's impossible that it's shooting slower.

It's also well below the expected performance of this model:



I tried in different types of lighting and with the device ether clamped to the barrel or resting on a surface and got similar results.

Needless to say I'm rather disappointed after my initial enthusiasm.

Anything else that might be affecting the measurement?

I have a Chrony Beta Master and it can be somewhat of a pain to set up and one of these small muzzle speed meters would be convenient I'm skeptical of their accuracy.  That plus the fact that reads mps instead of fps is the reason I don't own one.

I wanted one but could not compleat the order form  . After 3 true front 3 venders at aliexpress I gave up.

Now I had lding out to see if another cadwell goes on sale at amazon.  I missed the del posted here when they dropped to like 69 $ on a one day sale.

They're on eBay too if that helps you for a successful checkout.

I got mine from Amazon.
By the way,  it matches the readings very well to my Caldwell

I see a lot of that .   But like everything there's that lemon someone got to get.

How long was the shipping time from Amazon?   When I was looking they were priced more but the shipping times were forever like over a month+

If them shipped like normal in 3 to 5 days the extra cost would be worth it ( opinion).   But seemed to be on the same slow boat from china.

I have the model that clamps on the gun barrel.
I use it for air guns on my inside range.
It works good.

It was L O N G!
It was so long that I actually forgot that I had ordered it. One day it showed up on my doorstep. " What's this?"
" Oh, it really came."
I think four weeks or so.
Shipping has gotten faster now, I ordered a carbon fibre tube to stiffen a barrel, it came in two weeks via China post.

Anyway. I guess they got some enjoyment n the usa

I guess they got some in the usa now for quick shipping get by dec 5.

Looking through this topic, it seems that the results I got for power level II on the Streamline were probably spot on, JoeKool reported 695 fps with the same pellet and I calculated 692 fps with this chrony.  There must be something with the power level III interfering with the reading, perhaps it's the muzzle blast.  More testing to follow over the weekend.

It is hard to tell from the instructions, but the muzzle should away from the first LED, not right up close.
