Dave, Over 300 feet for longer than a 10 or 15 minute bounce dive. The only necessity for the redundant BC is to offset the gas requirements. Really it is never used unless in an emergency. I have never used it for real but we have practiced using it from deep dives. Just flip the BC over and place it over the bolts as you do your primary B.C. I loop a small loop of small bungie over the bottom bolt before I assemble the harness. This loop is placed over the power inflator mechanism to secure it at your right waist. There is no hose run to the inflator. Just orally inflate if needed.
