weights on twin tank

[sunkarm]

If i wanna dive double AL80, do i need to add more weights on my BC as compared to diving with single?

Thanks for the replies

I use the same weight. An empty tank is slightly negative but that is offset by the weight of the extra reg and manifold.

Al 80 doubles tend to get floaty on the tail when near empty though so you may need to redistribute the weight to account for that.

I dive 3 pounds lighter with my doubles.

I dropped some weight from a single 80 to double 80's. ~5lbs (I could of been a bit overweighted with my single.)

Ditto,

I only use a 3 mil wetsuit and no weight, but I am slightly more negative with the twins as opposed to when I dive a single.
