How Anti-fogs work
Mask fogging results from warm humid air inside the mask meeting a lens surface cooled by water. Warmer air is capable of holding more water vapor (water in gas form) than cooler air. Therefore, when air is cooled, a portion of its water vapor condenses into tiny liquid droplets, or “fog”. McNett® Anti-Fogs prevent fogging by creating a thin, invisible film on the lens which creates a “sheeting effect” - eliminating the formation of condensation droplets.

Diving is dehydrating – especially in tropical heat. Dehydration contributes to decompression sickness, fatigue and cardiovascular stress. To make up for water lost while diving, drink a gallon of water each day.

As a boat operator you should:
• Be able to recognize a “diver down” flag, a bright red flag with a diagonal white stripe, floating in divers’ areas.
• Stay the legal distance from a diver down flag. The law varies by state so check with your local authorities.
• Be on the lookout for bubbles breaking the water’s surface. There may be divers below who have strayed from their marked diving area.
