If you're using a camera or other accessory, don't enter the water with it. Have someone hand it to you after you get in. Note the current direction so you can swim into it on the bottom. and then descend, preferably along the anchor line or other descent line to the bottom. On the bottom, get your bearings and ,win into the current. Plan your Bali scuba dive and navigate so you finish near the boat with enough air so you'll be back on board with 20-40 bar/300 to 600 psi left in your tank. If there's a current, you'll find it easiest to ascend the anchor line, which keeps you from being carried past the boat.

If you hear the boat's underwater recall during the Bali scuba dive, remember to surface and look toward the boat for instructions, or as they direct during the briefing.

At the end of the Bali scuba dive, you usually surface in front of the boat, keeping one hand over your head for protection. When you break the surface, establish buoyancy and signal to the Bali scuba dive master or crew that you're okay. Avoid swimming back to the boat immediately below the surface because if there are other boats underway in the area, they will not be able to see you. If you're at the surface away from the boat, watch out for boat traffic. You can use an inflatable signal tube, whistle or other signalling device to attract the attention of the Bali scuba dive boat, or of other boats that might not see you.

It's not very likely, but if ,you surface and the boat's not in sight, stay calm and get buoyant. The boat may have slipped anchor or the captain may have needed to leave for an emergency. Relax and wait to be picked up. If the shore and a reasonable exit area are close, slowly swim in that direction.

When you reach the boat's exit area, don't crowd it. Exit one at a time and stay clear scuba divers climbing the ladder ahead of you because they can fall, drop a weight belt or have a tank slip loose, which you wouldn't enjoy one bit if you're directly beneath. Hand accessory equipment up before climbing the ladder, but keep all your other equipment in place until you're aboard (mask on, breathing from snorkel or regulator, etc). You'll usually need to take off your fins, but don't do so until you have a firm hold of the boat, because a current can carry you away from it and without your fins .
