This second generation, known as the CORE Gen2, incorporates a TDC Magnus™ rotary hop-up chamber, which guarantees a comfortable fit and reliable feeding. Along with this tube, the new Helium™ Flat Hop Eraser rubber is included, designed to improve the trajectory and stability of the shot. In addition, the nozzle is has been replaced by a sealed aluminum version, increasing the efficiency of the group.

The heart of the replica has also been improved with the Incorporation of the new V2 gearbox Æther™, which features a reinforced frame capable of supporting springs of up to M140. This gearbox also includes the ESA 2™ quick-change spring system, a practical solution that allows you to adjust the power of the replica without specialized tools or need for workshop. This makes it easier to tailor the performance of the speargun directly on the field of play, according to the requirements of each game.

One of the great novelties of this generation is the inclusion of HAL™ ETU module as standard. This electronic system allows the use of 11.1V batteries, providing an improved shooting response and the Ability to configure multiple advanced functions with great ease, all through the trigger.
