The scuba diving basics include mastering your buoyancy control and mastering your air consumption to extend your dive time and have fun diving.
For your own safety when diving in a drysuit you should leave your drysuit valve open, but close it a quarter turn from fully open to avoid any leaks. An open drysuit valve will then automatically vent if you ascend to let out the expanded air from your drysuit.
When you are diving in a drysuit you still need a BCD to attach your scuba tank to your back and for buoyancy when you first enter the water.
It’s best to use your drysuit and not your BCD for buoyancy when diving in a drysuit, as it’s better to use only one air cell for buoyancy to have only one to vent on your ascent. If you use your BCD for buoyancy you’ll need to use both, as you’ll have to add air to your drysuit to avoid drysuit squeeze.
The disadvantages of Nitrox diving include depth limits due to higher concentrations of oxygen and the cost of tank fills and specialist gear required to dive with Nitrox.
Pros And Cons Of Nitrox Diving: The top pros of Nitrox diving are improved diver safety and extended bottom times. Whereas the worst cons include depth limits and extra cost of diving.
