Why can't I dive twice on the same tank?

Gee, how hard is it to move a BC and reg?

It is very easy to move a BC and reg, but to change over from a single cylinder to a double cylinder is a major change that usually requires tools and adaptors. Plus you will need an additional cylinder or a replacement valve and someone to inspect and fill your cylinder.

I wear my doubles mainly because I need the practice in them!! Shallow dive or not! Plus I don't have a single tank wing, but the smurf is going to hook me up there ...

I guess we are pretty spoiled here in Anilao. After doing doubles with 2 side mounts. We return to the resort eat and rest, by the time we are ready to go back in the water, our twins and deco bottles are topped off and ready to go. No need to remove the bladder from the twins.

But I agree having to move your bladder to another twin tank setup is a pain!

Doing two tech dives in a single day is really tiring.

Alison, a female friend who is 5'3 manages her twin tank setup quite nicely! And she is so slim.
