■ Descent

Deflate your BCD completely and begin your descent while exhaling slowly.

All descents when using a dry suit should be performed feet first. Air may shift into the legs of the suit, making a head-first descent unsafe.

If you feel suit squeeze during descent, add small amounts of air to the dry suit to relieve pressure and maintain proper buoyancy control.

If you feel squeeze, add air

■ Ascent

During ascent, release expanding air from the dry suit using the exhaust valve.

Maintain a vertical position and raise your left shoulder so that the exhaust valve remains at the highest point. This allows excess air to vent effectively and helps control your ascent rate.
