Defog
Defog is a treatment or product used to prevent face masks and goggles from becoming cloudy underwater during snorkeling or diving activities. When instructors mention defog in their resumes, they're referring to their experience in teaching proper equipment maintenance and safety procedures. This is an important basic skill that ensures students can see clearly underwater, which is essential for both safety and enjoyment of the activity. You might also see this referred to as "anti-fog" or "fog prevention" in job applications.
