To enhance your technical diving skills, it's important to become familiar with your gear. This will enable you to quickly locate it in the event of a problem. It also helps to practice using your backup equipment. Even though you shouldn’t dive with your backup gear, it is a good idea to practice using it whenever necessary. This will help you to have a backup set in case something happens.
