Technical Diving

About

Technical Diving Gear — Equipment for Diving Beyond Recreational Limits Technical diving begins where recreational diving stops. Past roughly 40 metres, past the no-decompression limit, or past the point where a direct ascent to the surface is available, the assumptions recreational equipment is built around stop holding. You need more than one gas. You need more than one of everything critical. You need a rig that holds you horizontal so you can move through a cave or wreck without destroying the visibility behind you, and you need instrumentation that works when the electronics fail. That's what this equipment is for. Redundant breathing systems, multiple cylinders, mixed gases like nitrox, trimix, and heliox to manage narcosis and oxygen exposure at depth, backplate-and-wing systems built for trim rather than comfort at the surface, and the reels, lights, cutters, and markers that turn a dive plan into something you can actually execute. Technical diving also demands training, experience, and meticulous planning — the gear supports that discipline, it doesn't replace it.
