XuhalBallistic Chronograph Precision Shooting Speed Tester Slingshot Chronograph Bullet Bow Arrow Velocity Meter Measurement Tool with FPS MPS Readings for Archery Arrow Rifle Badminton Tennis

Got this on a whim to see if it would work for measuring .357 Magnum reload velocity. Didn't know how useful it would be, so I didn't want to spend three times as much on a "name brand" version.Turns out it works just fine. I started with nerf darts, then bb's, then took it to the range, and it worked like a champ. I had it mounted on a cheap plastic camera tripod that worked just fine. I thought I might have to build a sunshade for it, but it worked fine in bright sunlight and under the shade roof at the range.It didn't miss a single round out of 60 fired, except a few that were due to operator error, where I forgot to reset it after reading the measurements (by default it displays the reading for a few seconds, and then displays "--" waiting for the next shot. Then you can use the arrow buttons to scroll through the readings.) Batteries lasted through a 2-hour session at the range.I had it about 3 feet from the muzzle. When I was firing the magnum rounds, I noticed the unit swaying a bit from the shock wave. I think when I start using it with high-power hunting rifles, I will keep it about 6 feet from the muzzle to avoid damaging it.Mine also came with a spare support rod and "detection bar", so if I do accidentally hit or damage it I might be able to repair it. This was not mentioned in the listing, so I added a star!Only thing I didn't like is that it defaults to meters per sec, when I wanted feet per second. So every time I turned it off/on (frequently, to extend battery life) I had to make sure to change it to FPS. It would be nice if there was a permanent way to change the default.Not sure about the accuracy, and I haven't investigated a way to cross check it yet. The internal calculations involved are pretty simple, so I'm hoping it is ok. The measurements I got seemed in the ballpark for the reload data I have.

Very accurate, straight from the box and you cannot beat the price. Very good tool for air gun enthusiast. Bo enthusiast not the most heavy duty, but once again, look at the price, it works very accurate, and if you accidentally shoot it, you're not gonna cry

The media could not be loaded. UPDATE: The unit sat on a shelf since its first use, and now it doesn't power up. Despite having changed batteries it does not power up. This unit is junk because either the components are low quality, or the unit was not designed to last. **The product does work. It's relatively simple to operate, but I've been unable to shange it from meters per second to feet per second. Also, there isn't an easy way to scroll through the velocities. I more or less need to write down the velocity when I see it otherwise it takes forever to go through and see each velocity. Some more control options would take it from 4 stars to 5 stars.The upshot is, it will work on airguns as aell as firearms.For the money, it's functional and does the job, I just wish it did the job a little bit better.

LOVE IT!!! JUST WHAT I NEEDED! WORKS GREAT! WOULD BUY AGAIN!!! 10++++

Great for the money and seems to work well (I tested the speed readings in comparison to a friends high end chrony and it was close enough). A couple of irritating quirks. You really need to keep the barrel end at a BARE MINIMUM of 16" away from the front of the chrony to avoid interference and errors. Around 24+ inches is better. Every time you turn it off, you have to reset it to FPS from metric. Easily done but annoying that it doesn't remember. The unit is not really designed to be disassembled for storage and re-assembled for use. I have the space for it but I'm jealous of my friends chrony that disassembles and folds into a tiny little box for storage.Display is bright and easy to read. Unit is not really designe

This chrono seemed to work well, what i did not really like about it was the area for measuring the speed of an object is too small, Resulting in some real bad damage, MY FAULT but just something to consider if you were shooting through this.

I got this chronograph a few days ago, but today was the first chance I had to test it out. When I opened that package, I saw that it needs four AA batteries, so I knew I had to get some on the way home from running some errands. By the time I got home, I only had a few minutes till the sun would go down. I managed to put the chronograph together quickly; it's super simple; and I love the fact that it came with an extra light bar, an extra rod, and a couple of extra screws. I ran in the house and grabbed couple of air rifles, one of a known velocity, the other was one I wanted to test. By the time I got to shoot, the sun had already dropped below the treetops, but the chronograph still gave me good consistent readings. (Note: my old chronograph would NEVER have given me any readings with that low level of light!) The low-power target rifles I was testing gave me the results I expected. The .177-caliber one is a known 4.4 fpe rifle; and the .22-caliber version was giving me readings of 125 mps (410 fps); with my 13.43-grain pellets, that's 5 fpe, slightly more power than the .177 rifle, which is what I had expected, since they are identical (Haenel mode 1 rifles from the 30s) except for caliber. So far, especially for the price, I am impressed with this chronograph! Thank you.
