Dive Fin Care
The main purpose of dive fins is to propel the scuba diver efficiently underwater
Invented by the Italians during World War II, the SCUBA fins' main purpose is to propel the scuba diver efficiently underwater with the least amount of effort possible.
If looked after correctly, fins have an indefinite life. many of the fins in the rental department at Abyss are 20 years old and have been in constant use for that time.
How to Care For Scuba Diving Fins
Pre-dive Fin Care
Avoid placing the fins in a car boot on hot days as the temperatures inside the car boot can exceed the temperature tolerances of the fin, and the blades may distort.
During Dive Fin Care
Avoid standing your fins on the tips of the blades for an extended period.
Pos-Dive Fin CARE
Rinse thoroughly with fresh water and towel dry before final storage.
Spray the blades of the fins with a scuba grade Silicone spray after every half dozen dives to extend the fins life. Take particular care not to spray inside the foot pocket of the fin.
If the fin becomes hard to remove after a dive, then give a half second (no longer) spray into the pocket with Silicone, to make the fin easier to remove. Excess Silicone in the pocket will cause the fin to come off during the dive.
Dive Fin Storage
If you store your fins with the blades anything but perfectly flat, you may discover that a bent fin blade can become a permanent feature. Lying flat on a shelf or similar surface, out of direct sunlight, is best.
Store in a cool, dry and protected place out of direct sunlight.
Chemicals and Dive Fins
Avoid any contact with alcohol, oil, gasoline, aerosols, or chemical. If you expose any part of the fin to aerosol spray, as some aerosol propellants attack or degrade rubber and plastic materials.
McNett Silicone Spray is designed for use with dive equipment and the aerosol propellant used is harmless to rubber and plastic.
