SDI Dry Suit Diver Practice Test 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

What is one important factor divers must consider when using a dry suit?

Water temperature of the diving site

The depth of the dive

Weight distribution within the suit

Insulation requirements for warmth

When using a dry suit, the insulation requirements for warmth are a crucial factor for divers to consider. A dry suit is designed to keep a diver dry and provide thermal protection in cold water by trapping a layer of air or insulating materials against the body. The effectiveness of this insulation directly affects the diver's comfort and safety during the dive.

Understanding how different insulation materials work and how much warmth they provide helps divers determine the appropriate exposure protection for the conditions they will encounter. Diving without adequate insulation may lead to cold stress or hypothermia, especially in colder water conditions. Therefore, selecting the right thermal undergarment based on the water temperature and duration of the dive is essential for ensuring that the diver remains warm and safe underwater.
