The brand new ASTER II Bluetooth® EXPERT for V2 GB is the younger brother of the well-known TITAN II Bluetooth®. This is the font wired model.
Built-in Bluetooth 5.2 technology gives you direct access to ASTER II's settings and AEG telemetry through the Gate Control Station App, as well as the ability to use Gate's 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 old style trigger contacts.
ASTER II Bluetooth® raises the price-performance ratio by including an adjustable Quantum Trigger 2 and Bluetooth® 5.2 onboard. Now, out of the box, you can set sensitivity from ludicrous feather touch, through 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.
