Ok, dumb question time.
Since most PSD teams use SCUBA to do search, rescue and recovery work, how does your team train to monitor the amount of breathing gas remaining in the diver's cylinder during a zero visability dive? And I am not talking a low vis 6" to 3' dive, I am talking a "you run into things and really can't tell what they are" dive.
