The Sense Herakles RTA2 is a 25mm rebuildable atomizer, redesigning the deck to fit large coils while focusing chamber airflow into two oversized air slots and introducing a unified, dual quarter circle wicking system. In lieu of an internal quad airflow, the RTA2 features dual enlarged air slots that measure 8.5mm by 3mm in a curving design, placed directly below the coil for effective and efficient airflow. The shift away from quad airflow also results in a new wicking style, in which each coil shares between two unified wicking ports, resulting in easier wicking set-up and more effective wicking area. This RTA has two posts, dual terminal design with each terminal measuring 2.5mm in diameter and secured with PEEK insulators for durability. The Herakles RTA2 integrates a top fill system with a 6ml juice capacity. Airflow is fed into the build chamber from quad 7mm by 2mm air slots, with a classic airflow control ring to throttle and adjust airflow as needed. With all the wonderful functions, this new Version Herakles RTA will surely bring you a nice vaping experience.
