A must-have for verifying weapon power and safety: the AC6000 MKIII uses patented LED lens and IR sensor technology to deliver precise measurements of muzzle velocity (m/s or fps), energy (Joule) and ROF. The 36 mm measuring tube accommodates a wider range of barrel sizes for stable readings. The 240×240 color LCD clearly shows velocity, ROF, energy, BB weight and more; the unit stores the last 25 shots for quick comparisons. Power with four AA batteries (not included) or via USB-C (adapter/power bank not included). Includes 1/4-20 UNC tripod mount for stable setup. Rugged plastic housing and compact form factor make it easy to carry and use on the field.

Safety & usage warnings (GPSR / Italian compliance)

Read the supplied manual fully before first use and follow operational instructions.

Keep the device and accessories out of reach of children.

Use the chronograph only in a safe setup: always provide a secure backstop behind the device; do not place people, animals, or fragile items in the shot path.

Wear certified eye protection for the operator and any observers during measurement.

Batteries: use only the specified AA battery type; install with correct polarity. Do not mix new and used batteries or different battery chemistries; do not short circuit, puncture, disassemble or expose batteries to heat or open flame. Remove batteries if the device will be unused for extended periods. Dispose of batteries according to local regulations.

When using USB-C power, use appropriate, reliable cables and adapters; avoid unreliable power sources.

Avoid prolonged exposure to moisture, direct rain and extreme temperatures; keep the unit dry and store in a cool, protected place.

It is forbidden to tamper with, disassemble or permanently modify the chronograph: do not attempt to alter electronic components, optics or the housing. Unauthorized interventions may impair accuracy, compromise safety and void warranties. Use qualified service centers for repairs.

Conduct measurements with quality, consistent BBs and set the BB weight correctly in the device for accurate readings.

Auto shut-off: the unit will enter power-saving mode when idle or on low battery; replace or recharge power source as needed.
