Why do I dive a Twinset?

I first tried a twinset in my first year at Scuba Tech when I was a Divemaster Trainee. 

I did a discover twinset dive with my instructor, Peter Crane. I went on to complete my PADI Tec 40 and 45 in the last couple of years, both courses were conducted with a twinset. Since then I haven’t looked back!

A twinset is two scuba tanks manifolded together, with an isolator in the middle of the two valves.
The misconception with twinsets is that they are only reserved for technical diving and exploration. This is wrong; anybody can use a twinset with the right training, whether you are recreationally or technically minded in diving.

The two main reasons for using a twinset are...

One, redundancy – having that extra peace of mind and security underwater as you have two tanks instead of one.

Two, to extend your bottom time. Having two tanks is a great way of increasing your gas supply.



My twinset, without a doubt, is my favourite way to dive. 

I love the balance underwater and the stability of two tanks on your back instead of one. When weighted correctly, this is a very comfortable way of diving as well as a simple, streamlined set-up. 

However, they are very heavy, and do take some getting used to at first.


Furthermore, I want to be self sufficient underwater, I know I will never dive solo and that I will always have a buddy there to help me. However, if it ever comes down to a situation when my gas supply is compromised, I want to be able to have control and to be able to rectify the issue.
Diving a twinset can help me do this, as I can manipulate the valves and breathe off independent regulators.

This is what is known as a shut down – a way to close the valves in order to save your back gas in the event of an emergency.

Once you make the decision to dive a twinset, you know you are committed to diving as it is an expensive investment; you now need two of everything! 

I feel it is an excellent transition in my diving career as I grow as a diver as well as a professional. It may be expensive in the short term but it is worth it in the long run! 

A twinset brings comfort, control and flexibility in your diving whether you are in the shallows one day, or conducting a tech dive another.
