I'd like to see a source for the following quote from this article:

Good practice—two unfreezing regulators arranged as follows: first stage number 1 with primary second stage, BCD inflation hose and Submersible Pressure Gauges, first stage number 2 with secondary second stage (octopus), dry suit inflation hose and Submersible Pressure Gauges.

As placing the BCD inflation hose on the same first stage as the primary second stage is contrary to common sense since. 78.245.228.100 (talk) 16:45, 24 May 2012 (UTC)[reply]
