The Aqua Master's piston airflow system can be adjusted along the bottom airflow ring. The pistons rise and seal airflow and lower to increase the airflow. The 24K gold plated center pin is also connected to a top mounted hex screw which can be fully adjusted in order to further fine tune the air flow of the Aqua Master. This design allows for finer control of airflow and for a smoother vaping experience. The build deck of the Aqua Master features a two post, single terminals measuring at 2mm by 3mm, with top mounted Hex screws holding down the coils in place. Located on the top of the RTA is a 11mm tapered bore ULTEM proprietary drip tip. Juice enters the Aqua Master through a top threaded fill system and two large fill ports for ease.
