Acetech AC6000 MKIII Chronograph

A chronograph you have to squint at and write down is a chronograph you stop using. The AC6000 MKIII pairs to the Acesoft app over Bluetooth, so a string of shots is logged rather than remembered, and you can see the spread instead of just the highest number.

That matters most when you are tuning. Chasing a joule limit means watching consistency, not a single reading, and a phone screen shows you the shape of a twenty-shot string in a way a two-line display never will.

It also does the basics properly: a high-visibility screen, simple controls and intuitive menus, and a warning when a reading goes over the energy limit you have set. The Exclusive Edition adds an aluminium body.

Good to know before you buy

A site chronograph is the one that counts on game day. This is for tuning at home and knowing where you stand before you get there.

Frequently asked questions

What does the Exclusive Edition add?
An aluminium body. The measurement side is the same, so take the standard BT unless you want the metal housing.

Do I need the app to use it?
No. It has its own high-visibility screen and menus. The app is what turns single readings into a logged string you can actually analyse.

Will it read joules as well as FPS?
It measures rate of fire and FPS, and the energy-limit warning is what flags a shot over the figure you set. For the conversion itself, our joules guide has the maths.
