When planning diving, we try to avoid head-on collisions with strong currents. But the plan will never catch up with the changes. When the currents suddenly change, what should you do?
Efficient kicking ankle
Try to use the strength of the hips and thighs instead of the knees.
As much as possible to reduce the extent of kicking ankle. As a result, the ankle will remain within the streamlined form of the body. Exerting a big kick will not only produce more resistance, but will also reduce performance.
Keep your ankle under the water. It is a waste of energy to kick ankles on the water. If you are heading on the surface of the water, you can face up and lie back and keep the ankles kicking under the surface of the water, or dive 5 meters deep and then head to the top.
Keep pace and pace of action. The top stream should be to think of it as a marathon rather than a sprint. So you have to keep some energy and not sprint. At the same time pay attention to your breathing frequency and gas consumption, full sprint can easily lead to increased leg cramps and oxygen consumption.
Keep your body streamlined
Keep your body level. In a strong current, the smaller the volume, the less resistance it generates. Adjust the buoyancy of the BC to keep the body level. Only by maintaining proper neutral buoyancy will the body not be tilted as it advances. If you are heading up on the water, remember to keep your body straight and do not let your hips sink and bend.
Keep your wrist and arm position. Keep your wrists and arms close to your body. Try to make the external equipment close to the body. Place the watch set, flashlight, or camera as close to the body as possible. For example, keep the widest side of the camera body level with the body to reduce resistance.
Discard excess weight. If the current is really strong, it is best to abandon the heavy objects at hand. If the equipment at hand is really important, then discard equal weight lead. If it really threatens life. Then say goodbye to your camera. After all, life is more valuable than cameras, isn't it?
Avoid the currents
Currents vary from one dive to the next, but they are usually closer to the surface. The currents near the bottom are usually smaller. Try to dive to the bottom of the water and then move forward.
Use your hands. If the current is really strong, you can dive yourself to the bottom of the water and use your hands to climb the rock.
Head towards the nearest landing point. If all methods fail, head toward the nearest shore. Be careful when landing ashore. Do not cause physical damage from rocks and waves. Regardless of whether or not your shore is an ideal place, it is always easier to be found and rescued on the shore than in the sea.
Discharge
If the current is really strong, it is necessary to judge in a timely manner whether to abandon the landscape you want to see. After all, it is safe to dive and entertain. Do not use physical exhaustion or air to cause danger. This is not the case. Then it is also good to experience a laziness with your potential buddies. Remember to pay attention to your own depth and quantity, and send out signals in a timely manner after safe water, so that your submarine can find you.
Washing machine flow
If your diving experience still needs to be accumulated, please don't go to the dive sites that often appear with the flow of washing machines. Remember to remember! If you inadvertently encounter an upwelling, always pay attention to your computer watch, control the depth and ascent rate, empty the BCD as much as possible, and kick the water in the posture of the head and feet as necessary to counter the upwelling.
If you inadvertently encounter a descending flow, the same, always pay attention to your computer table, control the depth, take a kick from the top of the foot to kick the water against the falling flow, if necessary, inflate the BCD to increase the positive buoyancy.

The most dangerous thing is that the two streams alternately appear, which is usually referred to as the washing machine flow. Then you need to alternately use the above methods, and pay attention to your remaining air volume, and take the appropriate skills to safely return to the water.
