What is deep diving? Deep diving is underwater diving beyond the community norms. This may include adherence to prescribed limits established by authorities and/or communities. Elite deep diving is the most difficult type. The most dangerous side effect of deep diving is nitrogen narcosis. Deep diving is considered dangerous and requires extensive training. Deep diving is often done to explore the limits of human endurance and physical fitness.
Deep diving is permitted for commercial diving
Commercial diving involves deep dives. The tanks contain helium, oxygen, and heat-sparing gases. The living areas must be heated to prevent hypothermia. Depending on the depth, the temperature can vary from 85degF - 93degF. A special suit, called a hot-watersuit, is worn by divers to mitigate the effects of this environment. This suit is similar to a traditional wetsuit but has tubes running through.

Technical diving can be considered a non-professional form of deep sea diving.
Technical divers are technically recreational diving. But they have the ability to be trained in many aspects. These dives are more dangerous that recreational diving and they focus on what is below the water. They must be trained in techniques that increase their safety in a variety of environments, such as caves or underwater mountains. They must be able manage multiple gases. This is taught in certification programs.
Elite Deep Dives take more effort than regular Deep Dives
While regular Deep Dives are easier than Elite Deep Dives, Elite Dives are far more challenging. These missions take three times as long as regular Deep Dives, and are very difficult. These missions are not repeatable and you won't be able to get any Matrix Cores. You will still be able to collect Huuli Hoarders as well as their crafting materials. For Elite Dives you will also receive 'Today Specials' beers.
Nitrogen narcosis
The effects of deep diving with nitrogen narcosis are complex. These effects are dependent on depth, speed of ascent and other comorbidities. Divers with neurological impairments can still have residual impairment after treatment. However, most cases will result in a complete recovery. Deep divers should be aware that nitrogen narcosis can pose a danger to their health.

A dive instructor should supervise divers.
Deep diving is a skill that requires extensive training and experience. It can prove dangerous for novice divers, especially at deeper depths. Decompression sickness and gas narcosis are more likely. An instructor can help reduce this risk by providing proper planning in a controlled setting. An instructor can tailor training to meet your specific needs, such as night diving or dives in wrecks.
