With a SI TECH exhaust valve you can optimize your buoyancy control beyond belief. Set the pressure in the suit by turning the lid towards higher (+) or lower (-) buoyancy. Small adjustments of the setting during the dive will allow you to control your boyancy just by raising your elbow a few centimeters. No need for manual dumping by pushing the valve. Adjust the setting at intervals and the valve will do the job for you. Experience the sensation of a completely dry dive! Of course you can deflate manually - if needed.
