The Leviathan - NGRS optical is one of the most advanced ETU (electronic trigger unit) on the market.
It combines optical and switch sensors for better handling and durability.
Built-in wireless communication for quick setup using iOS or Android smartphones!
Tactile trigger switch has travel only 0,13mm long for ultimate hair trigger feeling.
Unique Real feel trigger system (RFTS) with integrated spring simulates trigger resistance like in the real gun. It adds secondary resistance with release after the fire. RFTS was designed by professional gunsmith for more realistic feel from shooting.
External output and input port serves for custom accessories.
Real time response for change settings -> immediately test result.
Easy installation into the gearbox (fully integrated inside the gearbox instead of the original trigger contacts).
New functions are for free for every user via online updates.

MAIN FUNCTIONS:
Adds new shooting modes independent for every position on the fire selector (SAFE - SEMI - AUTO)
Three adjustable bursts (range 2 - 20 shots)
It preserves empty magazine detection like the original gun
Rate of fire can be reduce to 40%. It add breaks between shots to reduce RoF. It gives fast trigger response even with very low rate of fire, just like in a real gun
Adjustable strength active braking (can be disabled)
Pre-cocking function for instant shot on SEMI fire
Delay between shots adds time in which isn't possible to shoot, it simulates the delay from gun reload or recoil (range 0,1 - 4,0 seconds)
Electronic fuse set sensitivity for high current detection to avoid any damage if something goes wrong
Low battery indication for 2S - 4S Li-Po and 3S - 4S Li-Fe
Virtual magazine simulates low capacity magazines, it will force the gun to stop shooting when it reach 0. There can be set warning after shot before empty magazine and how it will be reloaded
On the board are input and output ports for controlling external devices or Leviathan
Statistics screen shows shooting output with cycle timing, motor current consumption, rate of fire and temperatures. It allows you to do fine-tune gearbox upgrade
Application shows actual battery voltage value. Color lines indicates battery charge status where green is OK, orange will warn after each shot and red will not allow to shoot
User can save multiple settings under profiles
Update function fixes bugs and adds new features to the device
There are three shot counters. Total count every shot during the device lifetime. User counter can be reset by user anytime. Power-up counter is reset by battery connection
Error log shows errors made during the device life also can be erased by user
For better security wireless connection can be disable by the selector switch (can be deactivated)
Leviathan monitors current, voltage and temperature to avoid any damage when something go wrong.
Motor vibrates and beeps as a feedback for user
Programmed settings are saved in the Leviathan memory immediately after their change, so you can immediately test it and settings aren't lost when is battery disconnected or lost connection with smartphone
New functions are for free for every user via online update function

FIRE MODES:
Independent for every position on the fire selector (SAFE - SEMI - AUTO)
SAFE: no responding on the trigger pull.
Semi: it fires single shot per trigger pull.
Semi/BurstX: short trigger pull fires single shot, long trigger pull fires burst.
Binary trigger: it fires single shot when trigger is pulled and another single shot when is released.
BurstX: gun shoot burst per trigger pull.
BurstX+BurstY: short trigger press fires burstX, long trigger press makes burstX+burstY fire.
BurstX/Full: short trigger press fires burstX, long trigger press makes auto fire.
Full: gun makes auto fire until releasing trigger.
Virtual reload: pull trigger to reload virtual magazine.

TECHNICAL SPECIFICATIONS:
Easy installation inside the gearbox version NGRS by Tokyo Marui.
Stock gearbox needs light modification to fit Leviathan wiring without damaging them - see pictures:

Please skip this part, if you already bought CNC gearbox from Retroarms, because it has enough room for the wiring
If you want functions on SAFE position, cut the selector plate in the red area. WARNING: Mechanical locking will be disabled

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

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 - NGRS optical can be used with any common gearbox upgrade and gun rate of fire
Comes with wires to stock (loose end) with Deans/T-Plug connector to solder after gun assembly
There are high quality power wires 1,5 qmm (AWG16) with thin and hard Teflon insulation (PTFE) and signal blue wire 0.34 qmm (AWG22) with Teflon insulation too
Power wires outer diameter is only 2,10 mm and blue wire 1,30 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 anti-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 mechbox 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 contacts and trigger block, you will not need them with the Leviathan - NGRS

USE WITH BRUSHLESS MOTOR:
Leviathan can be used with brushless motor (Warhead, Option No. 1, etc.)
Activate function "Brushless motor" in the Leviathan app and use all available options without any worries.

PACKING:
Leviathan - NGRS optical drop-in electronic module with loose wiring to stock.
T-Plug connector, 2x heat shrinks to finish wiring at the battery end.
2x Screw with washer for securing device in the gearbox.
2x Foam to keep device in place.
Sheet with selector plate stickers.
Black Leviathan sticker 40 mm.
Installation manual in English.
