XS Scuba Aluminum Pony Bottle Tank - Compact Backup Air Supply for Scuba Diving, Snorkeling & Emergency Situations | Lightweight & Portable Dive Gear

This a basic aluminum 30cf pony tank. I'm a purely recreational / solo diver and 30 cf is enough to bailout of any "no stop" dive profile that I do. It comes with a combo DIN-yoke valve and will accommodate any typical first stage regulator. I've included a pic with it as a sling-setup. It comes with a factory sticker that says it was visually inspected at time of manufacture so any decent dive shop should fill it.The reason I say 4 out of 5 stars is because the description claims the manufacturer is "XS Scuba" .... however the tank neck is stamped "CATALINA" and the pro-valve is a "SHERWOOD" brand. Nothing in the package is "XS Scuba" and there's simply no excuse for an inaccurate product description.This is my fourth pony Bottle so far, but I am sorry to say it will be my last.The problem I have is its compatibility with compressors having Din receptacle.I discovered this problem while on holidays the hard way. The local scuba diving center did not have the proper adaptor to fill these bottles, and while most yoke bottles carry a valve that can accommodate din receptacle as we'll, these bottles don't. This problem could be easily resolved if the manufacturer would use universal type valves, but it seems that in order to save few cents, they preferred the strictly yoke valve. Pity. Now I have to pay for new valves.It is strange however that my 19 cbf bottle is equipped with the right valve. Go figure why...lo compre para bucear unos minutos con el pero creo que el tamaño que sigue para arriba esta mejor, aunque para emergencias esta excelenteSlow shipping, but happy with productVery good well constructed tank - quick delivery - use it to charge my PcP air rifles - will buy againExcellent product, very good and fast shipping thanks for the serviceI have the luckiest 7 year old in the world :)Thank YouPerfect tank but the duty charge is 90 bucks so buy local
