When features at the bottom are scarce, dive with a compass and ascend close to the bottom all the way to shore. When possible ascend near a rock face, up along your boat or dive flag anchor line. If unable to ascend at a protected spot, make sure you have reserve air, in case you have to try again. This holds true when near log booms. Broken fishing line can be dangerous, watch for it.
Fishing line is strong and hard to see.
Carry a diver's knife and be ready to cut yourself free, if entangled in fish line. There are a few animals in the North Pacific that could be dangerous and you should know about them. The dogfish sharks, are not known to attack people, but it's best to leave the waters when they are in a pack. Red, brown, yellow and water jellyfish can leave a painful sting, and are a nuisance, check your gear before removing masks and gloves. Most divers will leave the water if killer whales are in the vicinity.
