Description
Never worry about shallow water safety again with the WOLACH 0.5L portable backup air cylinder. Designed for recreational divers, snorkelers, and spearfishers who want reliable emergency air without lugging a full-size scuba setup, this compact tank fits easily in your dive bag or clips to your BCD.
Unlike most mini tanks that require a dive shop compressor to fill, this kit includes a heavy-duty manual hand pump – simply pump ~400 times (about 8 minutes of steady work) to reach full 200 bar (3000 PSI) pressure, anywhere from a boat deck to a remote beach. The adjustable shoulder sling keeps the tank secure and hands-free until you need it, and the included refill adapter works with any standard scuba tank for faster top-ups at dive shops.
Perfect for adding peace of mind to short shore dives, reef walks, or underwater photography sessions, this tank delivers ~the allows for underwater breathing for 5-10 minutes (at depths ≤5m/16ft) depending on your breathing rate. The three-layer filtration system effectively prevents dust and impurities from entering, ensuring cleaner inhaled air for the diver. . It’s also a smart add-on for boat dives where you want a backup air source without carrying extra heavy gear.
