REGULATOR SERVICE & REPAIR
Sean Smyrichinsky has more hands-on experience servicing more brands of scuba equipment than almost anyone in British Columbia. UB Diving provides professional regulator servicing, Nitrox preparation, oxygen cleaning, drysuit repairs, CCR support, cylinder inspections, expedition equipment support, and commercial diving equipment servicing.
Built Around Real Diving Experience
At UB Diving, equipment servicing is not treated as a side business. Our service department was built around decades of real-world cold-water diving operations throughout Vancouver Island and British Columbia.
Our lead technician, Sean Smyrichinsky, has more than 26 years of hands-on regulator servicing experience supporting recreational divers, technical divers, underwater photographers, instructors, commercial divers, expedition teams, and marine operations.
Unlike many facilities that primarily sell equipment, UB Diving actively operates dive expeditions, technical diving support systems, commercial diving operations, Nitrox systems, oxygen-clean equipment preparation, and cold-water charter diving.
This is scuba equipment support built by people who actually dive the environments your equipment is used in.

Straight Advice. Real Service.
UB Diving gives divers practical, experience-based equipment advice. We do not pretend every product is equal, and we do not push gear just because it is new, trendy, or easy to sell.
Some equipment is excellent. Some equipment is not. Some older gear is worth maintaining. Some newer gear is not worth the hype. We will tell you the truth as clearly as we can.
No Hype
We are more interested in what works underwater than what looks good in a catalogue.
No Guessing
Service recommendations are based on inspection, experience, condition, parts availability, and intended use.
No Disposable Mindset
Good older equipment is evaluated properly. Bad newer equipment is not automatically defended.
