Originally developed for the iconic GSL, its launch was a defining moment for spool valve marker technology. It was the first spool valve marker to incorporate Breech Sensing technology into the drivetrain, finally pushing spool valve efficiency into the realms of poppet valve markers. How does this Breech Sensing technology work? Simply put, it uses the pulse of air behind the ball to help close off the main valve at a predetermined valve chamber pressure. By closing off the main valve before the valve chamber is allowed to fully empty, it traps tail-end air that is at a pressure that would have no effect on the velocity of the paintball. This trapped air in the valve chamber would otherwise have been released, and wasted, down the barrel. By trapping this otherwise wasted air, it requires less air to top the firing chamber back up ready for the next shot. The result? A huge increase in efficiency, with zero downsides. It was a truly groundbreaking piece of technology in paintball marker development. But, as always, we continually push forwards to make improvements wherever possible, the result of which brings us an all new drivetrain to power the next generation of Geo fans.
