Long the favorite of serious divers, the SK8 compass will still operate even when tilted off level. The factory boot is not a favorite however, hard to don, and toooo tall. This replacement mount is lower profile, and is designed to accept 3/16 (5mm)diameter Bungee Cord. Bungee Cord mounted gauges are far easier to don than Buckled straps, and are depth compensating. New version will work with both black & white friction rings. This mount can be fitted with one continuous bungee, (as shown in the photos) or two separate loops for redundancy. Simple, secure, snap in installation, tough elastomeric material, remains flexible at low temperatures.
