text: Divers will usually enter the water with positive buoyancy, as this allows them to make final surface checks, signal to the boat that they are OK and co-ordinate descent with a buddy, but there are occasions when negative buoyancy entries are chosen to avoid excessive drift in a strong current, in which case all pre-dive checks must be done on the boat, the buoyancy compensator, and where applicable, the dry-suit emptied of gas, and the breathing apparatus function thoroughly checked before entering the water.
