Question
Posted : September 12, 2008
Hi Andrew, I doubt you will remember me but I posted a question on the forum in early August requesting your advice on how to get into technical diving. I am writting again to seek your wisdom on 'twinsets'. As I said before, I have only 14 logged dives and am thinking about investing in a twinset configuration. I am aware that their use is more involved than standard recreational configuration however does this necessarilly make them unsuitable for recreational diving? what exactly are the pro's and cons's? Many thanks.

My own business website has a lot of detail on inverting them and all the key issues so take a peek in the library, then under ADM tech tips.

Personally get more experience in before moving to this level of diving, and get a course such as the IANTD Advanced Nitrox Diver - which a good instructor will extensively cover kit configuration in.

i'm intrigued as to why you asking the question at this stage?

Twinsets can be used recreationally - this does however pose a number of issues that would need to be addressed - in terms of..

[1] how to dive safely with them and how to operate the manifold safely

[2] BCD suitability for twinset diving (i.e lift requirements, mounting and surface trim)

[3] Regulator and wing/bcd setup for optimum use and safety

Not all of these issues are addressed with recreational training... Inverting them brings a lot of issues to address sensibly - many argue it introduces more problems than it solves.. my website has a very long reply on the subject as well as how to do it...

regards Andrew
