! CAUTION !

Your weight requirements will change with changes in the

amount of divewear worn under the drysuit.

• To check your weighting, enter controlled water fully dressed in your scuba

unit, drysuit and insulation

• Vent all of the air from your drysuit by assuming a vertical position in the

water and opening the drysuit exhaust valve completely by turning it

counterclockwise until it stops. Lift your left elbow to make the exhaust

valve the highest point in the drysuit

• Vent air from your BCD until you become neutrally buoyant with your

lungs full of air. When you exhale you will start to descend. When you are

neutrally buoyant only the top of your head remains above the surface

• If you are not neutrally buoyant and continue to descend adjust your

weight until you are neutral with your BCD fully deflated

• Once you have reached neutral buoyancy with a full tank and your BCD is

fully deflated, add additional weight to compensate for a near empty tank.

See the table below for the estimated weight to be added

ESTIMATED CHANGES IN CYLINDER WEIGHT

The following table provides an estimate as to the change in the weight of a

single cylinder during the course of a dive assuming 80% of the air is

consumed. For double cylinders, multiply by two.
