The Gate ASTER II Bluetooth® Expert V3 GB is an advanced and versatile ETU (Electronic Trigger Unit) that brings a new generation of performance to V3 gearboxes. It is compatible with both AEG and HPA operation, supporting both single-solenoid and dual-solenoid HPA mechanisms. Built-in Bluetooth 5.2 connectivity allows for real-time settings control via the GCS mobile app without the need for separate adapters.
The ASTER II Bluetooth® offers precise trigger sensitivity adjustment, automatic Pre-Cocking, adaptive active brake, and accurate telemetry, which can be controlled directly from a smartphone or smartwatch.
The ASTER II Bluetooth® Expert V3 is the first ETU of this level to work with brushed and brushless motors (up to 11.1 V) and supports single-solenoid and dual-solenoid HPA systems.
Bluetooth connectivity allows users to adjust settings in real time without the need for a separate accessory such as a USB-Link or Blu-Link. Additionally, Wear OS and watchOS compatibility allows for real-time shot counter, remote trigger and other telemetry directly from the smartwatch.
ASTER II Bluetooth® is equipped with state-of-the-art optical sensors and a BGM220S processor, which ensure fast response, low power consumption and durability. In addition, a multilayer PCB with EMC shielding improves immunity and reliability.
