Gas Management for Scuba Divers (Metric) eBook

The comprehensive, illustrated, metric guide to advanced gas planning and management for safer scuba diving.

60 Pages. Printable PDF format. Fully Illustrated.

Scuba gas planning is a neglected fundamental competency in mainstream recreational diving training. It is simply the ability to accurately calculate your gas consumption and use that information to determine the limits of your dive compared to the gas supply you will carry when diving.

As a scuba diver, you should know how long you can stay at a planned diving depth; and allocate sufficient gas for your ascent. including a calculated gas reserve to mitigate against foreseeable emergency scenarios; such as air-sharing with a dive buddy.

This ebook describes the complete process and methods of planning safer recreational dives!
