JeffTron Leviathan Airsoft Drop-In Programmable ETU Module
(Type: V2 Optical - Black Curved Trigger / Wired to Stock)

Features

• Easy installation inside the gearbox version 2, compatible with Tokyo Marui standard
• You dont have to modify the gearbox V2 from the Krytac company. Simply cut the Leviathan bottom board
• 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
• 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
• 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.
• Specified for common batteries up to 17V (Ni-xx 8.4 - 12V, lipo 7.4 - 14.8V)

Main Functions:

• Adds new shooting modes independent for every position on the fire selector (SAFE - SEMI - AUTO)
• Three adjustable bursts (range 2 - 20 shots)

• 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
