Chapter 2- Diving Equipment Diving Equipment 41 your hood attached to your suit. If you are diving in colder water, you might want to use a dry hood attached directly to a dry suit. The dry hood keeps your head completely dry. Most hoods are fairly uncomfortable out of the water. However, once you are under water they are almost unnoticeable. Pressure equalization in your ears when you wear a hood may require special attention. Your instructor will address any special techniques needed for the type of gear you are wearing. Choosing the Correct Suit for the Conditions Some insulation is required for most diving activities and having the correct suit for the conditions is one of the keys to enjoying a dive. The correct suit for you might not be the correct suit for your buddy because your reaction to cold might be quite different. Also, depending on the area of the world in which you live, your resistance to cold might be less. For example, if you live in a desert climate, you might have to wear more insulation because your body is accustomed to high temperatures. If you live in a cold climate, you might be wearing less insulation in the water because your body is accustomed to colder temperatures. Use the following general guidelines when deciding what type of diving suit to wear: • 27°C (80°F) and warmer water. A skin suit is recommended. • 24°C to 27°C (75°F to 80°F) waters. A 2 mm to 3 mm full wetsuit or shorty is recommended. • 13°C to 24°C (55°F to 75°F) waters. A 5 mm to 7 mm full wetsuit is suggested. As the water gets colder, you also need to wear a hood and gloves. • 2°C to 13°C (35°F to 55°F) waters. A full dry suit is recommended. • 2°C (35°F) and colder water. Special training and equipment are needed to dive in water this cold. FIGURE 2-41. WEARING A HOOD HELPS YOU CONSERVE BODY HEAT. FIGURE 2-42.
