With all due respect to all the members of the board, someone needs to ask the OP what they think the purpose of a pony bottle is. Is it for bail out? Is it for back up in case of a poor or lost "dive buddy"? Is it to provide safety during a solo dive? What are the future needs of this diver? Do they include deco diving? Do they already own other cylinders and regulators? Are they traveling by air with this cylinder?
Please note that I am not throwing rocks at any one I just hope that they get what they need to dive safely. As an additional thought most technical and or solo divers prefer redundant gas not a pony bottle. Best regards and dive safely.
