Scuba Equipment Repair & Professional Dive Gear Service

Factory-authorized scuba equipment service, regulator repair, BCD service, full-face mask service, and public safety diving equipment repair. Local service in the Charlotte, NC area and mail-in service available nationwide.

Your regulator is life-support equipment — it deserves a real technician, not a parts-swap. At Sink or Swim Scuba, service is a core part of the business, with 20+ years behind the bench and factory-authorized status. Every regulator is bench-tested on our A.I.R. (Atmospheric Inhalation Resistance) Flow Analyzer so it breathes exactly the way the manufacturer intended. Local divers drop off; divers and public safety teams nationwide ship in.

Factory diagnostic & bench testing

We don’t guess — we verify. Every regulator is bench-tested on our A.I.R. Flow Analyzer so it breathes to manufacturer spec. For Interspiro diving breathing systems, we use specialized Interspiro Spiromatic test equipment to inspect, service, troubleshoot, and verify performance — evaluating operating pressures, leakage, breathing-valve function, and regulator performance as part of proper Interspiro service procedures. That’s factory-level verification most shops simply can’t offer.
