I'm a Canadian diverwho just relocated to Ottawa, after spending 20+ years diving up and down the coast of British Columbia.
I dive a Russian IDA-64 CC oxygen rig (shallow dives) and Fenzy adaptations (pendulum rigs) for SCC nitrox a little deeper. Currently building slowly a homebuilt CC rig (KISS).
The IDA rig is a great shallow water rig, light and back-mounted so never in the way. Other than the depth restriction (as with any O2 rig) it is sweet.
