When you possess an underwater regulator equipped with a DIN connection, it is crucial to employ a reliable DIN cap that remains affixed to the regulator at all times. Typical DIN caps present an issue: once attached, they cannot be screwed on. Consequently, they tend to stay loose, posing a constant risk of being misplaced or lost.
Best Divers identified this issue for me, and collaboratively, we discovered an effective solution. The innovative Best Divers cap features a rotating buttonhole, allowing it to stay connected to the regulator and at the same time be able to be screwed onto it. This design ensures that the cap remains conveniently attached, eliminating the worry of losing it. It was the year 2003.
