The key feature of 3D Diving's techincal courses is they are performance based. That means that each diver who is issued a technical qualification through 3D Diving will have accomplished specific dives to specified depths. If for instance a diver has a 45m rating on their card then they have performed dives satisfactorily at that depth.
At 3D Diving short cuts are not an option. Each course is designed to provide the experience and training necessary while maintaining the highest level of safety. All students discuss their future diving intentions and previous experience with their instructor prior to any programme commencing.
