What distinguishes ASTER II Bluetooth® from the competition?

Extraordinary quality-to-price ratio:

• ASTER II Bluetooth® gives you total flexibility thanks to Bluetooth® 5.2 and compatibility both with AEG and HPA. You can update your firmware and get new options, connect additional accessories, check telemetry. Now – right off the shelf. At no extra charge.
• GCS app for iOS, Android, macOS or Windows
• GCS app for your smartwatch (Wear OS or watchOS) – real-time data like BB counters & remote trigger!
• compatibility both with AEG and single solenoid HPA engines
• hair-trigger – up to 35 trigger sensitivities for the first millimeter (0.04 in) of movement & up to 680 in the full range
• configurable trigger reset (hysteresis)
• top-notch automatic pre-cocking
• free internet firmware updates
• ASTER II Bluetooth® is a part of the GATE Ecosystem
• lowest in the market current consumption – deep sleep mode with only 140 uA current consumption prevents battery discharge
• built-in voltage boost converter means trouble-free operation with weaker batteries and increases the switching efficiency
• 3.75 V ready – ASTER II Bluetooth® operates at very low voltage (even 1.2 V during the shot), which is important in high-tuned AEGs, where the voltage under load drops significantly
• sensor supporting Infinite Torque-up, DSG, SSG, 19-tooth, and standard gears
• the possibility of using a mechanical trigger lock
• extended compatibility with brushless motors – works perfect with all popular brushless motors even with 11.1 V batteries
• Multifunctional programmable I/O port – allows to connect bolt-catch sensor, magazine sensor, and more

What makes ASTER II Bluetooth® so special?

• Everything you need out-of-the-box
• Adjustable Quantum Trigger 2 included in the kit. Set trigger travel with screw and trigger sensitivity in the app.
• Built-in Bluetooth® 5.2
• Noise-resistant trigger detection algorithm
• Hair-trigger out-of-the-box. Even 35 trigger sensitivities for the first millimeter (0.04 in) of movement & up to 680 in the full range
• Additional protection against interferences thanks to multi-layer PCB with EMC shield
• Automatic Pre-Cocking: 0-5
• Trigger sensitivity adjustment without any limitation – what’s more, you can now adjust Trigger Reset (hysteresis)
• Improved cycle detection
• Active brake adjustment: Adaptive / 1-100%
• 343 selector modes. All possible combination of: SAFE, SEMI, BURST, BINARY, BURST/AUTO, AUTO & SEMI RAMPING
• The GCS app enables firmware updates via the internet, which means instant application of improvements
• Both ASTER and ASTER II Bluetooth® are now compatible with QUANTUM TRIGGERs:
  Quantum Trigger 1 (QT: 1A1, 1B1, 1C1, 1E1)
  Quantum Trigger 2 (QT-2A1) – over-travel movement adjustable with screw

What is an ETU?

It is an Electronic Trigger Unit replacing trigger contacts and the cut-off lever, which takes control of your AEG.

What is the self-learning automatic pre-cocking?‎

• thanks to pre-cocking, you gain trigger reaction similar to real life
• automatically sets piston position
• easy-to-use – just set one of the 5 modes: 0-5
• automatically adapts to the battery voltage and rate of fire
