ok.. so I am OW certified.. but havent looked into getting equiptment til now (a year later) and I am looking for some equiptment for when I go scuba diving in the keys this summer. A BC.. does that include the Regulator? or is that separate? How many regulators do you need..lol I have seen primary, secondary, octopus.. etc. I know you personally need one and then there is one extra in case of emergency with your diving partner, but I jsut am confused. I guess I am asking, what all I need to buy to have a full fledge gear set up. I know you need a tank, BC, weight belt (if it isnt built-in), mask, regulator (is it included in the BC?), fins, and a wetsuit (if needed). am I missing anything? thanks for any help!
