Velcro pocket for left outer-thigh:

A canvas bellows home made pocket is sewed to wet suit at left outer-thigh, at hand level with straight arm. It contains the frequent use accessories.

Accessories:

Usually, a Delrin spool, a Fox 40 Whistle, spare mask (in it's own mesh bag) and wet notes, with a plastic pencil. Optionally, at places where dive masters dislike knives, a hidden Scubapro foldable knife. Depending on local conditions, some other stuff will be put inside, always snapped to the elastic band with a plastic clip.
