To enhance your technical diving skills, it's important to become familiar with your gear. This will make it easy to locate the equipment you need in an emergency. 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. You will have an extra set in case of emergency.
