I have one but today it appears to have essentially stopped working.  I still get readings but they make no sense.  In a string of about 10 shots I got from 178 to 425 mps.  This is from my Avenger which I have previously measured at around 880 fps.  Fill pressure was well above regulator setting for all these shots.  I got a couple obviously incorrect readings before and recharging the unit fixed it.  So I tried that today but it appears to have not worked.  I charged it for a couple hours.  I guess I'll try overnight and if it still gives me inconsistent and incorrect readings I will have to do something else (probably buy a "normal" chronograph). 

Compared to the FX this unit is an amazing buy and if I only get a years use out of it I would still consider it worth buying.  But my old conventional chrony worked well for over 10 years (when the light was right) and would probably still be working if I had not shot it.

Thing is you could of bought a higher end one and get that as well.  This way you only out $30 not $100+ when it goes bad..


I've had to make sun shields out of cardboard  for the sides the sun just right can throw it off or error.    One day I had it on the barrel and when I cocked the rifle (springer) I seen the display flicker.    So the movement through the sunlight was activating it.  So I cut cardboard for the sides and taped them on , seemed to do the trick.

Lol.. I put this shield on to see the display in the sun

I charged it overnight and it is reading fine again today.  I've had the sunlight issue and will remember the cardboard shield.  But these days I normally just I shoot a few pellets into an old car ramp (4 layers of 2x8) in the garage and the chrony is easily visible. 

I may still buy a more conventional chronograph so I can measure velocity while shooting groups.  Hanging this little chrony off my two PCPs changes the POI.  My shooting bench sits on an elevated side porch (so I can get more than the 25 yards distance from my back porch to the back fence where I hang the pellet trap) and I could easily put a little shelf on the handrail of the porch for a conventional chrony.  But with this one working it isn't high on my list any more.

Seemed like a guy got one from the place/ guy on Amazon and he said he had a time using .177 with it .

So far mine doing well with .177. 

But useing it in full sun or partial shade I guess flickers the sensors  when I moved it cocking a springer.   Just setting on the bench and shooting through it I don't see that deal at all. Just when I'm swinging it around on the end of the barrel. (?)
