NEW SCUBA DIVER GUIDE: What is a “two tank dive?”
So, you’re new to scuba diving and have begun planning for a “two tank dive.” What does this mean?
This can sound intimidating, I know. But it’s not! You do not need to carry two tanks on you, which is definitely what I worried about when I first heard this term.
A “two tank dive” is actually two separate tank dives. You will gear up (with just one tank), and scuba dive for as long as possible. This will likely be until when you or your buddy runs low on air, or you are tired. You will surface, exit the water, take off your gear, and rest. After a bit of time, an instructor will switch out your tank. At this point, you will go on a second dive with your brand new tank.
Is a two tank dive standard?
Short answer? Yes.
Long answer? It’s totally up to you. Every person is different and feels comfortable with different diving capacities. Especially for someones first ever scuba dive, it is common for one dive to be enough.
Your dive instructors will plan for a two tank dive. In other words, they will have two tanks for you to use if that is what you choose to do. The sport of scuba diving, however, is so personal that it is hard to specify an exact standard. This is one reason why it is so important to dive with people or a company you trust.
What else do I need to know as a new scuba diver?
Honestly, there is not much to it. You will be guided by knowledgeable and experienced instructors. There will be a dive brief before entering the water to explain to you information about the area and the dive itself. Most of the information you need to know, you will learn on site.
Aside from your tank(s), your gear will include:
- BCD – This is the vest that attaches to your tank.
- Regulator set – These are the tubes that come out of the tank. One tube connects the oxygen to your BCD, and two others connect to mouth pieces for you to breathe from.
