What happens if a diver does not decompress?
If you don’t decompress when scuba diving you will end up with decompression sickness, which can be fatal. All dives are decompression dives, which means you should always ascend slowly after a dive and where appropriate carry out decompression stops. As a safety precaution you should also perform a safety stop too.
Do you need a backup dive computer?
You don’t even necessarily need a backup dive computer. A simple, analog dive timer (also known as a dive watch), and an analog depth gauge should be adequate and will let you log the dive. There are even dive watches with built-in depth gauges so you can have both in one device.
What do you need in a dive computer?
A basic dive computer only monitors depth and time; this means you’ll still need to use a pressure gauge and compass. If you’d like to do away with your pressure gauge, you’ll want to choose an air-integrated dive computer. This option allows you to run an air hose from your tank to your computer.
When should you clear a mask?
When mask clearing, it’s inhale through the mouth, exhale through the nose. When water enters your nostrils, simply exhale through the nose to clear it. Start small. Add just a small amount of water to the mask at first, until you get the hang of it.
Should you accidentally exceed your dive computer’s no decompression limit?
As a recreational diver, you should never plan to exceed, or even dive right up to, the no-decompression limits), but if you accidentally find yourself past your dive time or maximum depth and running to deco, it’s good to know what to do.
