4 Weighting and Trim
It is very important to dive properly weighted and trimmed out in a well balanced
equipment configuration. This will make your diving both safer and easier.
Tank selection is important in helping to achieve correct weighting.
Diving in cold water with a Drysuit and thick undergarments it is recommended to
use low pressure Steel tanks as the primary SM tanks which will help to offset the
extra positive buoyancy of the exposure protection.
High pressure Steel tanks are not recommended as they tend to be too negatively
buoyant and make handling SM tanks underwater very difficult.
Diving in warm water in a wetsuit it is recommended to use Aluminium primary
Side Mount Tanks so as not to be excessively over weighted.
Aluminium tanks should always be used for stages and deco tanks so that as you
add extra tanks to your configuration you do not become excessively over weight-
