- It uses optical sensor actuated by sector gear cam for perfect semi and burst fire timing
- For fire selector position is used optical sensor too - it works with sticker provided with Leviathan
sensor cyklu selector plate sensor
- Tactile trigger switch makes short click for great hair trigger mod.
- Unique real feel trigger system (RFTS) simulates trigger feeling like in the real gun. It adds secondary resistance with release after the fire. Feeling is comparable to shooting with real caliber 22lr in AR15

- Thanks to advanced electronics, Leviathan - V2 optical can be used with any common gearbox upgrade and gun rate of fire
- Completely made wiring allows the fastest and the easiest installation into the gun, it is long enough for all kind of weapons with battery placed in the stock. No soldering is needed
- The wire length between the gearbox and the battery connector is 290mm
- There are high quality power wires 1,5 qmm (AWG16) with thin and hard MPPE insulation and signal blue wire 0.34 qmm (AWG24) with MPPE insulation
- Power wires outer diameter is only 2,06 mm and blue wire 1,24 mm
- Board covered by conformal coating, it protect Leviathan against damage from water
- On the board is input port for controlling output port, 3rd burst, external trigger, magazine reload, etc. and output port for the hop-up chamber BBs illumination, powering electric magazine, flashlight, laser, etc.

- For right pre-cocking function is necessary to have in the gearbox functional ant reverse latch. WARNING: it increases wear and tear on the gearbox.
- Specified for common batteries up to 17V (Ni-xx 8.4 - 12V, lipo 7.4 - 14.8V)
- Device increases gun rate of fire and battery holds longer, than with basic wiring
- With active braking ON piston isn't partially stretched, spring is fully released, parts in mechabox aren't under strain and nozzle locks hop-up chamber in greater part (depends on ROF)
- In weapons with very high rate of fire (ROF) active brake solves multiple shots in semi mode
- The braking effect is the most powerful with high torque motor. Note: Lower braking intensity spares the motor coils.
- Remove from the gearbox: cut off lever, trigger, trigger contacts and trigger block, you will not need them with the Leviathan - V2 optical

SAFETY WARNING:- Installation of this device into the gearbox requires advanced technician skills!
- Please read these information before installing your device to prevent any damage.
- Short circuit or incorrectly connected battery will cause immediate damage to the device which is not covered by the warranty. It can lead to fire or even battery explosion.
- Disconnect battery, when you aren't using the gun! Otherwise you will fully discharge the battery. Because the device drains small amount of current from the battery all the time.
- Do not connect battery when gun pointing towards you, another person or an animal.
- Do not modify, repair and put into any kind of liquids or thermal shock the Leviathan - V2 optical.
