Replacing your standard trigger unit with a Jefftron Levithan means more features, performance, and reliability through advanced computerized functionality.
Unlike most other computerized MOSFETS on the market, Jefftron Leviathan allows the user to change between pre-set profiles they can configure with unique settings.
Whether the user needs to view or configure settings, statistics, diagnostics, and even firmware updates; this can be done on the fly via Bluetooth with the iOS or Android app.
Delivering competitive features, value, and long term performance.
Our technicians here have been carefully following the initial launch and development of the Jefftron Levithan. This is in part to the extensive combination of features and quality these units deliver. Jefftron is dedicated in developing this technology with regular updates in firmware as well as improving their hardware based on community feedback in the field, as well as local techs. We are impressed by the Jefftron Leviathan and will be utilizing it in future Umbrella Armory Builds.
- Adds new shooting modes independent for every position on the fire selector (SAFE - SEMI - AUTO)
- Three adjustable bursts (range 2 - 20 shots)
- 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-pol and 3S - 4S li-fe
- Statistics screen shows shooting output with cycle timing, motor current consumption, rate of fire and mosfet temperature. It allows you to do fine-tune gearbox upgrade
- Application shows actual battery voltage value. Color lines indicates battery charge status
- 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
- For better security wireless connection can be disable by the selector switch (can be deactivated)
- Leviathan - V2 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 - V2 memory immediately after their change, so settings aren't lost when is battery disconnected or lost connection with smartphone
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.
- Easy installation inside the gearbox version 2, compatible with Tokyo Marui standard
- In the most cases is no modifications needed in the gun or Leviathan - V2
- It uses micro switch actuated by sector gear for perfect semi and burst fire timing
- CNC trigger included with package has screw to move its zero position. Thanks to it, shot can be made by very short trigger pull, it is called "hair trigger" modification
- Thanks to advanced electronics, Leviathan - V2 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
- 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
- The wire length between the gearbox and the battery connector is 290mm
- Board covered by conformal coating, it protect Leviathan - V2 against water
- For right pre-cocking function is necessary to have in the gearbox functional antireverse latch
- Specified for common batteries up to 17V (Ni-xx 8.4 - 12V, lipol 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
- Remove from the gearbox: cut off lever, trigger, trigger contacts and trigger block, you will not need them with the Leviathan - V2

- Installation manual in English
- Installation of this device into the gearbox requires advanced technician skills!
- Please read these informations 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 bettery all the time.
- Don't connect battery when gun pointing towards you, another person or an animal.
- Don't modify, repair and put into any kind of liquids or thermal shock the Leviathan - V2.
