The Horizon Arctic V8 Sub-Ohm Tank features one of the first eight coil structures in Sub-Ohm Tanks allowing for absolutely staggering amounts of vapor production, a spiral splash proof vent, a 4ml tank capacity, and a top fill system. Horizon has once again elevated the bar with one of the first eight core coil structures today, allowing for massive amounts of vapor production, while also implementing compatibility with single, dual, quad, and Ni200 Nickel coil structures under the new V Coil platform. Each V Coil is designed for optimal wicking and output, utilizing a new, enlarged platform and thread pitch. An additional RTA option allows users to customize and utilize their own personalized coil structures in conjunction. The newly designed Spiral Splash Proof Vent drastically eliminates spit back issues, while a top fill system allows for easy filling of the 4ml tank capacity. The capability of outstanding output, the integration of highly effective systems such as the Spiral Splash Proof Vent , top filling, and a 4ml tank combine to create Horizon's newest tank in the Arctic V8 Sub-Ohm Tank.
