The advantage of the Volcano Digit lies in its large digital LED display, which immediately and precisely informs you of the operating status. The Volcano Digit communicates better with the user and its electronic control system works even more precisely than the bi-metallic regulator on the Volcano Classic. The EASY VALVE is characterized by very easy handling and minimal maintenance work. Designed to accommodate users who would rather not clean the valve and mouthpiece or attach a new balloon. Once the Easy Valve can no longer be used, you simply replace the old with a new one or with the new EASY VALVE balloon with adapter you can just attach a new bag like the discontinued Solid Valve. The filling chamber is cleaned and re-used.
