A replacement “boot” or Mount for the Popular Uwatec Digital Bottom Timers. These “Hockey Puck” style bottom timers are sold under several names, OMS, ScubaPro etc. This replacement mount is lower profile, and is designed to accept 3/16" or 5mm diameter Bungee Cord. Bungee Cord mounted gauges are far easier to don than Buckled straps, and are depth compensating. 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.
