Can you sex a crayfish? Could you converse without speaking? Would you look for a sheet bend in a kinky bed? Could you find your way back to the start just using your arms? When size matters, does your tank have what it takes?

Answers and general skills theory are in the following pages. Use them to sharpen your knowledge! There's stuff on navigational techniques, tying knots and even an electronic calculator to automatically work out your tank's capacity at depth.

Remember that this material is no substitute for formal training nor intended to be comprehensive. The purpose is to increase your understanding of scuba diving, not to tell you what to do. It would be extremely dangerous and foolish for you to dive without formal training in dive planning and scuba skills.
