HAL ETU™

HAL ETU™ Electronic Processor Unit ensures safe switching, protecting the internal components, improving trigger response, extending battery life, and increasing the gun’s rate of fire. It also enables the safe use of Li-Pol batteries 7.4V and 11.1V. The name HAL is derived from the principle of the Hall effect, which allows the unit to detect trigger sensitivity.




HAL ETU™ Features:

  • Trigger sensing based on magnetic sensors and the Hall effect.
  • Active braking.
  • Binary trigger (fires on both press and release).
  • Adjustable trigger sensitivity (5 levels from 20% to 100%).
  • Adjustable pre-cocking (6 levels).
  • Programmable SEMI fire modes (semi-auto, binary, AUG, sniper mode with delay).
  • Programmable AUTO fire modes (full-auto, semi-auto, 3-round burst, 5-round burst).
  • Easy programming via trigger.
  • Low battery warning alarm.
  • Compatible with brushless motors (e.g., Specna Arms Dark Matter or Warhead).




Warning:

In AUTO mode, the gun will first fire a three-round burst before switching to unlimited full-auto.
