What items of SCUBA equipment should I (a novice) buy first?
The first thing I would get is a good, solid regulator. This is life support equipment and the last thing I wanna do is rent it, you have no idea what that regulator has been through or when it was last serviced. Second I would get a dive computer. They make life alot easier, but make sure you know how to dive tables. The rest you can buy as you see fit… but the above 2 are the first things I’d buy. The last thing you should worry about is an underwater camera. Buy one of those when you have pinpoint buoyancy control. Or better yet, rent one and see how much it changes your dive.
