Gear Selection and Fitting Guide
Place the mask against your face without using the strap, then inhale gently through your nose. A well-fitting mask will stay in place using just the suction from your gentle inhalation. If air leaks in, try another style or size.
Fins should fit snugly but not tight enough to cause cramps. For open-heel fins with boots, ensure the heel strap holds securely without pressure points. Full-foot fins should fit like a comfortable shoe with no sliding movement.
A properly fitting wetsuit should be snug against your skin with minimal water movement inside. Check for flexibility at joints and ensure no binding at the neck, wrists, or ankles. Thickness should match your diving environment’s water temperature.
Equipment Maintenance and Care
Proper maintenance ensures your essential scuba diving gear works correctly when you need it most—underwater. After every dive, especially in saltwater:
- Rinse all equipment thoroughly with fresh water
- Allow gear to dry completely before storage
- Store in a cool, dry place away from direct sunlight
- Check for signs of wear or damage regularly
- Service life-support equipment according to manufacturer recommendations
