I have 4 Worthington X7-100 tanks to sell. They have 2 dives (cave) on them. Original hydro dates 07/06 and 08/06. They come with original din/k valves and boots. My dive buddy and I bought these for sidemount use, but we like our 95's better. Asking $300 O.B.O each if I/we meet in the Sarasota, Tampa, High Springs Florida area. If they need to be shipped, additional shipping cost apply. Pm me if interested.
