AceTech AC6000 MKIII BT Chronograph

AC6000 MKIII BT Muzzle Velocity Chronograph by AceTech

Do you want to know exactly what muzzle velocity and energy your weapon has? Check what effect the upgrade part you just installed has? Or simply be sure that you won't be sent home from the event because your weapon is too powerful? And have all the results and settings data clearly displayed on your mobile phone in the app? Then you should get your own chrono. The AC6000 MKIII BT is an advanced chronograph designed for measuring muzzle velocity, energy, and rate of fire. It uses patented LED lens and IR sensor technology to deliver highly precise readings. Compared to previous versions, it features a larger 36 mm measuring tube, suitable for wider airgun and airsoft barrels.
The 240×240 color LCD display clearly shows velocity, ROF, energy in Joules, BB weight, and more. It includes a memory of the last 25 shots and auto shut-off when idle or running on low battery. You can power the unit with 4 AA batteries or via USB-C cable (not included), allowing charging from a wall outlet or power bank. It also includes a 1/4-20 UNC tripod mount for stable setup.
Its plastic construction is rugged yet compact – perfect for both field and range use. BT version (Bluetooth) includes connectivity to the AceSoft mobile app (Android/iOS) for convenient data viewing on your phone.

Tips for Accurate Measurement

• Use high-quality BBs of consistent weight (commonly 0.20 g).
• Always wear eye protection (including observers).
• Place the chrono on a stable surface and shoot straight through the center of the measuring tube from short range.
• Ensure there is a safe backstop behind the chrono (no people, animals, or breakable property).
• Fire at least 3 shots to obtain an accurate average.
• After using gas-powered replicas, clean the sensors more frequently as per instructions.
