The brand new ASTER II Bluetooth® EXPERT for V2 GB is the younger brother of the well-known TITAN II Bluetooth®. Built-in Bluetooth 5.2 technology gives you direct access to ASTER II Bluetooth® settings, AEG telemetry, and the ability to use our smartwatch app, the tactical computer STATUS, and other future devices of the GATE Ecosystem. Today you can use ASTER II Bluetooth® with your AEG and tomorrow with a single solenoid HPA engine. This makes ASTER II Bluetooth®, right after TITAN II Bluetooth®, the most versatile ETU in the world replacing trigger contacts. ASTER II Bluetooth® raises the price-performance ratio by including an adjustable Quantum Trigger 2 and Bluetooth® 5.2 onboard. You get cutting-edge technologies at a reasonable price. Now, out of the box, you can set sensitivity from ludicrous touch through hair to full movement. Automatic pre-cocking, trigger sensitivity adjustment, Active Brake settings with top-class adaptive mode and the Binary Trigger are all available via Bluetooth® with the GCS app. Extended compatibility with brushless motors – ASTER II Bluetooth® is compatible with popular brushless motors even with a supply voltage of 11.1 V. ASTER’s smart fuse protects your AEG’s battery, motor, and the controller. This feature, along with the optical sensors, makes ASTER II Bluetooth® one of the most durable ETUs on the market. ASTER II Bluetooth® is not just a regular ETU/EFCS mosfet. It is a complex system that turns your AEG into future-proof advanced training equipment with built-in Bluetooth®. ASTER II Bluetooth® has a coating in the MIL-V-173C military specification, making it resistant to weather conditions.

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
