Technical diving is defined by being exposed at the ceiling, which prohibits the diver from reaching the surface at any time during the dive. This can be due either to a literal ceiling (a cave, wreck, or virtual ceiling) or a decompression obligation. In such cases, mandatory decompression stops are required on ascent for anyone who exceeds the NDL. This may require the use of special equipment (e.g. Twinsets, Sidemount, special gas mixtures, and more training are needed to perform those stops as well as other tasks on ascent. This will optimize Nitrogen offgassing.

The technical sidemount was completed the next day. This involved adding our 50-percent oxygen tank and 100 percent oxygen tanks to either side. This will increase your profile underwater. You must ensure that the tanks are as slim as possible. A couple of clips are located on either side of your waist. When your tanks become positively buoyant and you inhale, adjust the clip to match your tank position. It is important to keep your breathing as smooth as possible. Your breathing will change from one tank to another every few minutes. The pressure in each tank will drop at approximately the same rate. If a regulator or tank fails, you will still have gas to breath. Comfort and enjoyment can only be achieved by gaining experience. I spent the next few day doing deco dives using the sidemount rig with Evolution co-owner David Joyce, a Trimix instructor and Tec diver. We visited the Japanese Mogami wreck at 164ft, where I was charmed by the pieces of old gas masks and uniforms.
Sidemount can be a boon for all divers, but it's especially useful for cave diving. (It was actually cave divers that invented sidemount. These are some of the benefits:
Television, magazines, and stories from a friend are all good sources of information about the underwater world. Exploring it and getting away from the surface can be exciting. How do we keep exploring? What exactly is technical dive?

Sidemount rigs were created originally for cave diving.
The choice of equipment is very individual and different divers will recommend different styles. In general to go with a well known brand is useful as they stand for quality, performance and configurability. Some of the best brands are Apeks, Diverite, Halcyon, OMS, Scubapro, Hollis and some newer brands like xDeep or Tecline. The preferred divecomputers for tech divers at the moment are Shearwater products, whether it be the Petrel 2 or Perdix, the flexibility of the algorithm, handling and display.
One of the most significant innovations in equipment cave divers have seen since the beginning of this century has been the transition from backmounted to sidemount doubles. Many cave divers now sidemount. There may even be more open-circuit sidemount cave divers that backmount cave divers.
from 170 to 350 feet
While conventional scuba diving has a recommended maximum depth of 130 feet, technical divers may work at depths ranging from 170 feet to 350 feet, and sometimes even deeper.
