The perfect insurance policy to ensure your latches stay put. The GoPro Underwater Camera Housing is a well proven quality product for underwater use. However, at depth, the pressure on the housing causes the latch to loosen slightly. An accidental bump at depth could result in flooding upon ascent as the pressure decreases.
This rubber strap is not your typical rubber band, which is why they cost $0.95 each. They are made of a special EPDM (Ethylene Propylene Diene Monomer) rubber material produced by Aero Rubber in Tinley Park, Il. It is designed to resist salt water and UV rays helps keep your latches in place both above and below the surface. The length, thickness, and width of these straps are custom cut for MAKO so we can offer to you some additional piece of mind.
