There have been few upgrades to a markers drivetrain that have yielded such significant performance improvements as the IV Core brought to the Geo platform in the GSL. The IV Core brought about not only a significant uplift in outright efficiency to the Geo, but also noted improvements in both feel and sound signature.
So overwhelmingly positive was the response to the implementation of the IV Cores new breech-sensing technology in GSL that the next logical step was to make its benefits available to a much wider audience than just the 750 fortunate GSL owners.

Efficiency gains can vary with the different models of Geos, but there is ALWAYS a significant gain
