Upon the successful completion of the RAID Cave 1 diver program you will be prepared, confident and most importantly competent in being able to conduct simple navigation following established permanent guidelines, be able too safely and effectively lay your own guideline whilst following your dive plan, established gas management protocols and ensuring that you have enough gas for any unexpected event that may lead to having to utilize your structured contingency planning.
As the RAID Cave 1 diver program is the very first step in our technical overhead environment program, it’s designed to present you with particularly interesting challenges that are steeped with a very long interesting and diverse lineage. Many divers consider cavern and Cave diving to be the foundation of all technical diving regardless of the environment or whether the dive is conducted using open circuit or closed circuit rebreathers.
One thing we will guarantee upon completion of the RAID Cave 1 diver program is the skills that you will develop during the program can be applied across most other forms of diving and will develop and hone your understanding and skills as a diver no matter where your future adventures take you.
