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

I did not need one that did more. Simple operation, simple speed test, no other calculations needed.Was just a simple speed test and not high priced.Just be sure to assemble according to instructions. Will no work if you install LED bars backwards.

Works very well for our use. Just as accurate as some of the expensive models. Very easy to set up and disassemble.

I've had this since May 2024. It seemed a little flimsy so I've left it set up on a tripod and just move it all together outside. No big deal for my situation though but I don't think disassemble and reassemble would be such a good idea for long.I've probably shot around a 1000 pellets from .177 to .25 caliber and 22 LR through it. No problems and minimal errors show up. I use it in a shaded spot. I just use it for velocity (after you hit the FPS button each on/off cycle) and out of routine calculate the ftlb of the energy myself. I feel confident in the accuracy, I mainly am looking for ballpark increase/decrease. I have compared it to documented velocities and get (+-3%), so that's good by me. I didn't want to tie up a lot of $ for what I'm doing. I'm happy with it. Honestly I didn't think it would last this long! If I need to replace it at some point, I'll get another just like it.

This Chronograph is junk. I know I waited too long to use it to make a return, my fault but....I've been to the range 3 times now and tried to chronograph approximately 50 test data rounds through this chrono. I've been able to get 6 readings, 1 mps 308, 4 fps 308 and 1 fps for a 22 caliber rifle.I've tried every combination possible to get it to work. Even turned it off after each shot to start anew and only 1 time did it take a reading. The top pieces are Left and Right. The blue lights are on. The FPS setting is acquired by pressing the sq button on startup and then setting. It just does not function properly. I only had 1 rifle to build test load data for so I went cheap. I hosed myself and nothing that can be done for purchasing a piece of junk. Do NOT purchase this chronograph.

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.
