The 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's Bluetooth® settings, AEG telemetry, and the ability to use our smartwatch app, STATUS tactical computer, and other future devices in the GATE ecosystem. Today you can use ASTER II Bluetooth® with your AEG and tomorrow with a single solenoid HPA motor. This makes ASTER II Bluetooth®, right after TITAN II Bluetooth®, the world's most versatile ETU replacing trip contacts. ASTER II Bluetooth® raises the price-performance ratio by including an adjustable Quantum Trigger 2 and integrated Bluetooth® 5.2. You get cutting-edge technologies at a reasonable price. Now, right out of the box, you can set the sensitivity from a ridiculous touch through the hair to a full motion. Automatic pre-arming, trigger sensitivity adjustment, Active Brake settings with first-class adaptive mode and Binary Trigger are available via Bluetooth® with the GCS app. Expanded Brushless Motor Compatibility: ASTER II Bluetooth® is compatible with popular brushless motors even with a supply voltage of 11.1V. ASTER's smart fuse protects your AEG's battery, motor and controller. This feature, along with optical sensors, makes ASTER II Bluetooth® one of the most durable ETUs on the market. ASTER II Bluetooth® is not just a normal ETU/EFCS mosfet. It is a complex system that turns your AEG into a future-proof advanced training equipment with built-in Bluetooth®. ASTER II Bluetooth® has a military specification MIL-V-173C coating, making it resistant to weather conditions.


ASTER II Bluetooth® gives you complete flexibility thanks to Bluetooth® 5.2 and compatibility with both AEG and HPA. You can update your firmware and get new options, connect additional accessories, check telemetry. Now, ready to use. Without aditional costs.
