The Drysuit Diver course teaches you how to stay warm, comfortable, and in control when diving in cold water. You’ll learn proper drysuit selection and fit, inflation and exhaust valve use, buoyancy management with both your BCD and suit, emergency procedures, and how to prevent and handle common issues like feet-first ascents or air migration. Through confined practice and at least two open water dives, you’ll develop precise buoyancy control and confidence in cooler environments—extending your dive season and opening access to quarries, lakes, and cold-water destinations year-round.
