Shopper Do I need a 1st stage for this or is this all I need to use with a pony bottle?
LeisurePro S This octo down not come with a first stage. So it depends on the pony bottle you have. If you have just a "normal" pony bottle with just a regula valve on it, you will need to get a first stage piece to use this octo with it. If you have a pony bottle with an integrated first stage, you can hook this right to that.
