Drysuit Diver


Why Dive Cold? Dry suits can make diving more enjoyable any time water temperatures drop below 24°C/75°F — and are essential in water below 15°C/60°F, or when depths approach 100 feet and beyond. Dry suits open the door to activities such as deeper wreck diving and ice diving, and can extend your diving season well beyond just the warmest months of the year.

Safely using dry suits, however, requires special training. That’s where the Drysuit Diver specialty course comes in.

Among the many things you will learn as part of this program:

  • Dry Versus Wet: How dry suits keep you warm in ways no wet suit can ever hope to match.
  • Dry Suits and Accessories: A comprehensive guide to dry suit features and materials, as well as to undergarments, hoods, boots, gloves and other accessories that are unique to dry suit use.
  • Using Dry Suits: How to plan and organize dry suit dives, as well as to the specialized procedures for donning dry suits, ascents and descents, and buoyancy control under water (as well as what to do when the unexpected happens).
  • Dry Suit Care and Maintenance: Getting the most from your investment in a dry suit.
