ACETECH Airsoft Chronograph AC5000 BBS Shooting Measurement Speed Tester Chrono for Gamers

Good quality and it measures very accurately and consistently

Works as advertised. No problems so far. Just don't shoot it. I just use it to test different ammo and pressures of a couple shots each. Convenient to pack and no set up just turn on and shoot through it.

So far I've used this with 2 nerf guns (short dart and hyper) and an airsoft pistol. It's accurate, easy to setup/use, and can run off of 2 AAs or power from a micro USB source. You're also able to enter ammo size and weight to get a measure of kinetic energy (not necessary, but cool to know). Although the description says this isn't meant for or won't work with nerf darts, it does just fine. As long as your able to shoot the dart through without hitting the interior it measures it just fine. Also when using something co2 powered, back the muzzle away a few inches otherwise the condensation cloud will throw it off and give you some crazy numbers.

seems to be accurate, has been good for measuring my GBBRs before hitting the field. the unit feels pretty light and cheap, which lends itself to portability but makes me wonder about its size. its a good price though.

Always works and is very accurate. It's also small so easy to take around with you and use when you go on trips for events.

Accurate, consistent, and easy to use. The AC5000 read my rifle exactly where it should be, and when I checked in at the field, their chrono matched mine almost to the digit. Menu navigation is simple, readings are stable, and the unit feels sturdier than most budget chronos. Honestly, it’s nice owning a chrono that doesn’t start an argument at check‑in.

I know this chronograph is Is made for airsoft, however it does work very well air and pellet guns. I'm impressed with how well this thing reads. My previous chronograph Was an expensive Caldwell chronograph that would not register up to half of the shots I play through it. This reads much better than that one does, and used them both simultaneously to test it and this one is quite accurate to within 5 FPS of the Caldwell. The input is a lot easier to use than I expected it to be, and I like that it can register multiple shots and keep them in order for you. Also can keep track of your shots per second or minute. The only negatives I can see of it is that the port to shoot through is small so You have to keep the end of your barrel pretty close to it. ( I actually did hit the lower part of the Orange ring a few times and to its credit it did not break) and that Projectile weight only goes up to 9.9 grain which is fine for .177 but useless for any larger calibers. However Centering that information is given to give you the Joules per cm Which I really don't care about anyway as I will occasionally get my foot lbs which I calculate on my own. Holly function I went this to do is give me the feet per second and it does that very well. This unit does use 2 AA batteries but it also has a micro-USB port That you can attach a phone charger to it and not use batteries.

Works Great, and I like everything about this chronograph.Fair price also , I've had a while no problems at all.
