The TITAN II Bluetooth is GATE's flagship electronic trigger unit, and this is the HPA version - wired to drive a solenoid engine rather than a motor. It brings the full TITAN feature set to an HPA build, which is what turns a good engine into a properly configurable one.
Two things set it apart. The optical trigger sensor gives 50 sensitivity levels within the first millimetre of trigger travel, so you can set a hair trigger that breaks almost on contact or deliberately lengthen it for milsim. And the dual optical gear sensors count each tooth and, uniquely, detect the direction of rotation - which is what gives it genuinely precise cycle control and lets it run DSG, SSG, 19-tooth and standard gears alike.
Everything configures over Bluetooth 5.2 through the GCS app on Android, iOS, Windows, macOS and even Wear OS and watchOS smartwatches. Fire modes, ROF, pre-cocking, active brake, magazine simulation and live telemetry all adjust without opening the gun - and firmware updates arrive over the internet rather than needing a cable.
A multifunctional port takes accessories: bolt-catch button, magazine sensor, a tracer in the hop-up chamber, an electric magazine. It works with both single and dual solenoid HPA engines, though a dual solenoid setup needs an additional cable.

Good to know before you buy
Choose the wiring to match your build - rear for a battery in the stock, front for a battery in the handguard. This is the HPA version; if you are running an AEG with a motor you want the AEG variant instead, so check before ordering. A dual solenoid engine needs an additional cable, sold separately.
Frequently asked questions
Is this the AEG or the HPA version?
The HPA version - wired to drive a solenoid engine. If your gun is a standard AEG with a motor, you need the AEG wiring version instead. Ask us if you are unsure which your build takes.
What does the dual gear sensor actually do?
It counts each gear tooth and detects which direction the gears are turning. That gives far more precise cycle control than a single sensor, and it is what lets the unit run DSG, SSG and 19-tooth gears reliably.
Do I need a smartphone to use it?
To configure it, yes - the GCS app is how you set fire modes, ROF and trigger sensitivity. It runs on Android, iOS, Windows and macOS. Once configured it plays perfectly well without a phone.
Will it work with dual solenoid engines?
Yes, but a dual solenoid setup requires an additional cable that is not included.
Can you fit it for me?
Yes. Fitting an ETU means opening the gearbox and rewiring the trigger circuit - we do that in our workshop and configure it through GCS before it goes back.
