how to behave during a scuba dive with current to stay safe

 When diving in current, the main goal is to avoid fighting the water, stay with your buddy/group, and keep enough gas for the conditions...and fly

🌊 Diving safely in current

• Check the current before entering. Watch the water, ask the guide about direction and strength, and understand the dive plan and pickup procedure.

• Experience the current step by step. begin with a light current and increase the speed when you are comfortable.current can be scary as it overhelm yourself and it is stronger than you

• Whenever practical, start against the current. This can make the return easier because the current helps you back. For a drift dive, follow the planned direction instead.

• Stay close to your buddy and guide. Current can separate divers surprisingly quickly. Don't let the group become spread out.

• Stay close to the reef or bottom when appropriate. Current is often weaker near the structure. But never grab or damage coral.

• Streamline yourself. Secure your SPG, alternate air source, camera and other equipment. A horizontal position reduces drag.

• Don't fight a strong current. If you're getting tired, signal your buddy/guide. Move closer to shelter, change direction if appropriate, or end the dive.

• Watch your breathing and gas more frequently. Swimming against current increases exertion and gas consumption considerably. Turn/end the dive earlier than you would in calm water.

• If caught in a strong current, don't panic. Depending on the site and dive plan, swimming diagonally or perpendicular to the current may help you reach weaker water rather than exhausting yourself trying to swim directly against it.

• For a drift dive, drift with the current. Maintain good buoyancy, stay together and let the boat follow the divers rather than trying to return to the entry point.

• Carry an SMB/DSMB and signaling devices. A surface marker, whistle and—where appropriate—light are particularly important on current dives.

• If separated underwater, follow the agreed lost-buddy procedure. Commonly this means a brief underwater search followed by a controlled ascent, rather than chasing the other diver through the current.

• On the surface, stay positively buoyant. Inflate your BCD, keep your mask and regulator/snorkel available, signal the boat with your SMB and don't exhaust yourself swimming after it.

⚠️ Most important rule

If the current is stronger than your experience, fitness or training can comfortably handle, don't make the dive—or abort it early. There is nothing wrong with changing the dive site or waiting for better conditions.

For students/new divers, I would emphasize one simple rule: never exhaust yourself trying to beat a current. Stop, communicate, find shelter or end the dive.
