Over the years, divers have tried countless do-it-yourself methods for keeping stage and deco regulator hoses under control: Rubber band or inner tube sections can be difficult to grip. Rubber surgical tubing oxidizes rapidly and wears out quickly. Shock cord can be difficult to fasten securely. Surgical tubing and shock cord roll along the side of the tank, making them difficult to manage. Dive Gear Express elastic hose retainers offer a superior alternative for keeping hoses under control.
