Cheap Chrony

[ginoe]

i've recently acquired this chrony after reading up on it in the various forums. i was happy to see that they worked out the bugs on the 1st generation device & started making the ps2 in texas. when it arrived, i was immediately disappointed when i saw stamped on the plastic housing MADE IN CHINA (but after reading capt t review - only the housing is made in china).

i'm glad i made the purchase, the device works well.  i've chrony'ed my various ag's through it (which made me disappointed again when i discovered the actual fps is not what the declared fps is). example: my stock 1377 stated 'up to 600 fps', i chrony'ed mine to be an average of 458 fps @ 10 pumps with a 10.5 grain pellet. i guess i have to pay closer attention to the meaning of '...up to...'

i am afraid to chrony my big bore .50 dragon claw with this (or any of my powder burners) due to the harsh muzzle blast. i was considering macgyver'ing up a blast shield to protect the chrony face  (see pic of mock up).

for the cats that used this on their powder burners, what was the distance from the muzzle to the face of the chrony?

I doubt it would stand up to the blast of a .50 cal. Most I would try is a .25.

Your lucky to have gotten one that has the proper tripod threads. Mine does not and I have tried to contact lee with no luck about it. I stopped recommending it.

I stopped recommending it.

because of the tripod issues or were there other problems?

i searched the 'net & found a youtube of this chrony, around the 1:30 mark it shows the tripod mount.

(edit)
btw: i re-chrony'ed the 1377 with a lighter 7.9 grain pellet & i get an average of 521 fps (getting closer to 600 fps).
i'll have to grab those crosman lead free silver eagle hollow point @ 4.8 grains & see how fast they are (probably higher fps, will have to see how accurate).

As I mentioned in my review, I have fired 10mm, .44 Spcl., .45ACP & .45 Long Colt through mine, no issues!
I think any air gun, big bore or not won't be an issue  I put everything right on the built in muzzel rest, no chance of shooting your chrony. Again, no issues. I love mine.

I got one of these after reading a review here.  He lost my order and I had to call after a couple of weeks to get it straightened out.  When I got it, the tripod threads were cross threaded.  I fixed that by running a tap through it.  After that, it worked fine.  I'm not sorry I bought it, because it's cheap and works well for pellet guns, and I didn't mind fixing the threads.  I wouldn't recommend it in general except for extremely cheap frugal people like me.  The guy that runs the business was nice enough on the phone.  If I were to order again, I'd place the order on the phone rather than online.

I stopped recommending it due to the makers poor communication ( read zero )

I just ordered a combro to compare to this one and will make a  comparison as soon as it arrives.

Yes I know I could a ordered an F1 or higher, but I need something that does not require fiddling with indoor lights.

I have a combro. I think they're pretty good.
