Inherent Buoyancy

Measured in the water with size large BCs unless noted.

|||||| |---|---|---|---|---| | None | Less than 1 lb. | ** 1 -2 lbs.** | ** 2 - 3 lbs.** | More than 3 lbs. | | | Mares Prestige MRS Plus | Aeris 5 Oceans | Bare Blackwing | Tusa Conquest | | | Oceanic Cruz | Bare Voodoo | Scubapro Glide Pro | | | | Scubapro Equator | Bare Blackjack | | | | | | Cressi Aquaride | | | | | | Cressi Light Jac | | | | | | Cressi Travelight | | | | | | Zeagle Ranger LTD | | | | | | Zeagle Zeus (med) | | |

NOTE: Every pound of inherent buoyancy is an extra pound you must carry in your ballast system. When it comes to inherent buoyancy, less is always best.

FLOW RATES

We test flow rates to determine whether or not a BC's deflation valves will stay ahead of the inflation valve to avoid an out-of-control ascent in the event the inflation valve sticks open. In a heads-up ascent position, starting out with the BC totally empty and loaded with ballast equaling 20 percent of its mfg-stated buoyant lift, the inflation valve was simultaneously activated for 20 seconds with each of the deflation valves. Each time, the BC was checked to see if it was able to remain negatively buoyant. Industry standards require that at least one of the following deflation valves must keep up with inflation.

ERGONOMIC CHART EXPLANATIONS

MOST IMPORTANT

• Ascent Control: An evaluation of how easily the BC can be used to control a normal ascent.
• Attitude and Stability: Evaluated while swimming under water to determine if the BC will keep the diver in the proper swimming position without wobbling.
• Weight Ditching: An evaluation of how easy or difficult it is to ditch weights in a simulated emergency situation.

MODERATELY IMPORTANT

• Valve Operation: Evaluated by the ease with which a diver can find and use the oral and power inflators, the oral deflate held overhead, the pull dump and the remote exhaust valve(s).
• Comfort and Adjustment: Checked both in and out of the water with BC strapped to a tank.

MINIMALLY IMPORTANT

• Assembly: Performed on deck without instructions. (Although BC's should be supplied with clear and complete instructions, most divers will not take the instructions with them on the boat. )
• Weight Loading: An evaluation of how easy or difficult it is for a diver to load weights and secure the system while wearing the BC.
• Pockets: Tested in and out of the water, this is an evaluation of how easy or difficult it is to access and use pockets.

Scale of 1 to 5
5 = Excellent
4 = Very Good
3 = Good
2 = Fair
1 = Poor
