UTD Student & Diver Procedures #19 - Battlefield Calculation

This is a sub book, # 19, of the more extensive UTD Student and Diver Procedures Manual. In this sub-book we discuss UTD/DIR skills and procedures and the relevant physics and gas laws needed to do quick math and the variety of easy to remember formulas and principals to be able to do "on the fly" scuba-math. We cover everything from gas planning and management, to O2 toxcity to blending and mixing breathing gases.
