This tank has a born born on date of 10/08 and a current hydro from 02/19 so there is still either 2 or 3 years of life left to where you can fill it at dive shops depending if they go off of when the hydro or born on date expires and then longer if you have the means to fill the tank yourself. I bought this tank used 2 years ago and it has worked flawlessly for me holds air with no issues. I am only selling because I purchased a larger used 60 minute tank that was posted so I can go longer between fills. I'm asking 100 plus you pay shipping and I will ship anywhere in CONUS I accept papal F&F or you pay 3.5%. This is a great way to get a setup and try this hobby out without having to spend a fortune up front. Thanks for looking.
