What do you need to scuba dive?

Basic Scuba EquipmentYes, while most every piece of equipment is rentable. I would only invest in your own mask, fins, and snorkle to begin with. Wait and make sure that you are really into the sport before dropping the several thousand dollars on the BCD, Regs, Tanks, and such. It's kind of a waste if you find out that you don't do it enough, or just aren't interested in doing it again. The dealer will give you a great deal if you purchase all the gear at once, don't be fooled, wait it out. Get certified, and go from there. AnswerWell, you can rent virtually every piece of equipment you'd need, but the essentials are a mask & snorkel, fins, wet siut (optional for some climates but recommended), a tank, bouancy compensator (BC or dive vest), regulator & hoses and a dive belt with weights. You can also use gloves, a flashlight and other accessories. At the bare minimum though, you'd need the tank and hoses, BC, weight belt, mask and fins.
