Is it easy to operate the i3 lever when effecting a rescue of an unresponsive diver using an i3 BCD at depth (found with reg in mouth)?
The reason I ask this question is that, with a conventional corrugated hose and power inflater, the rescuer can visualize the unresponsive diver's power inflater, dump air conveniently, and add air easily (power or oral) all with left hand manipulation. The i3 system separates the point of control for power inflation/deflation and oral inflation. It's a minor point, but it should be considered in the context of a rescue scenario. I suppose if the mechanism catches on in the scuba community, rescue students will learn to "feel around" for the i3 lever and rapidly switch to the oral inflation hose if necessary. To me, it seems like the new device is unnecessarily complicated, though.
