Another look at the AceTech Predator MK II tracer unit with Indomitus Airsoft trying it and sharing what he thinks about it. The Predator MKII contains the Acetech Brighter C module, which is the smallest and lightest tracer unit for airsoft AEG/GBB. Its small size allows for easy installation into silencers or hand-guards with an inner space larger than its dimensions (Diameter: 28mm or 1.1 inches, Length: 56mm or 2.21 inches). The device should not be disassembled to prevent electrical shock and will automatically switch off if idle for 5 minutes or if the battery is low. The power indicator flashes once per second to show remaining power (Green: high, Orange: medium, Red: low). Do not look directly into the muzzle to check installation to prevent accidents. To extend the built-in Li-Poly battery’s life, follow the manufacturer’s instructions.
