GATE HPA kit PULSAR D2 and TITAN II Bluetooth® EXPERT V2 - Rear Wiring

GATE PULSAR D2 and TITAN II Bluetooth®

Are you looking for the most precise, stable and technologically advanced HPA system on the market? Do you want instant trigger response, zero drops in muzzle velocity and a perfectly consistent BB trajectory even at high rate of fire? Then the combination of PULSAR D2 and TITAN II Bluetooth® EXPERT is exactly what you are looking for. PULSAR D2 is an evolution of the original PULSAR D, redesigned based on years of real-world player feedback. Thanks to a completely redesigned poppet valve and a larger compression chamber, it delivers an extremely wide power range from approx. 0.5 J up to 3.6 J without the need to change any internal parts. Open-bolt and closed-bolt modes, an innovative BB feeding system and a central nozzle return spring ensure excellent consistency, stable muzzle velocity and flawless operation. Combined with the TITAN II Bluetooth® processor unit, you gain absolute control over trigger sensitivity, rate of fire, firing modes and advanced diagnostics. TITAN II Bluetooth® is GATE’s most advanced processor unit, designed for V2 gearboxes, suitable not only for AEG but also HPA builds. It features the most precise trigger sensor on the market. Thanks to Bluetooth® 5.2, TITAN II connects directly to the GATE Control Station app (download here), allowing full configuration, firmware updates, shot statistics, battery monitoring and more. The system also supports smartwatch integration and the GATE STATUS ecosystem for real-time insight during gameplay.

Improvements of PULSAR D2 Compared to PULSAR D

• Redesigned poppet valve:
  The new valve design ensures a stable air supply across an extremely wide power range without the need to swap internal components.
  
  
• Larger compression chamber:
  Increased air volume provides more consistent FPS (muzzle velocity), improved BB spin and higher accuracy with different hop-up rubbers.
  
  
• Wider power range:
  Stable operation from approximately 0.5 J up to 3.6 J without the need to change the poppet valve (PULSAR D required configuration changes).
  
  
• Central nozzle return spring:
  Replaces the original tappet spring solution, ensuring symmetrical nozzle movement, improved feeding reliability and reduced wear.
  
  
• Quieter system operation:
  Optimized air flow and firing cycle significantly reduce noise compared to the previous generation.
  
  
• Higher accuracy and consistency:
  Improved BB rotation and elimination of typical HPA issues such as unstable hop-up performance and FPS fluctuation.
  
  
• Higher rate of fire without power drop:
  Stable FPS even at high rates of fire up to 40 RPS, with no difference between SEMI and AUTO modes.
  
  
• Greater tolerance to imperfect alignment:
  PULSAR D2 is less sensitive to receiver tolerances and installation precision compared to the original PULSAR D.
  
  
• Even better integration with TITAN II Bluetooth®:
  Advanced automatic cycle synchronization and faster, simpler calibration via the GCS application.
