SSI Extended Range (XR) Nitrox Diving

… or “how can I safely extend bottom times on deep dives?”

Deep Diving. Dives deeper than 100 feet. What does that conjure up for you? Wrecks, hydro-coral, unique photo opportunities, and more? How often do you go Deep Diving? And what is it that keeps you from diving below 100 feet? Most likely, the answers are “not very often,” and “because of the limited bottom time we have in which to explore these dive locations,” respectively. Enter Extended Range (XR) Nitrox Diving.

Invalid Hydro Stamps on Scuba Cylinders

The Department of Transportation is seeking assistance from divers to identify Scuba Cylinders with an invalid Retesters Identification Number (RIN).  The RIN is applied after hydrostatic testing, which must be performed every five years to ensure Scuba Cylinders are in a safe condition.  It identifies which facility performed the hydrostatic test.  Each facility performing these tests is required to be licensed and verified to ensure public safety in the testing and handling of Scuba Cylinders.
