In recent years a vast amount of general knowledge and scientific information has been developed and made available about diving and our underwater playland. Much of it is highly technical. Computers are now available for the technical type of diving, like the VR Technology's VRx Dive Computer found at Scuba.com. Recreational divers do not have to become experts in these fields, but they should have a working knowledge of the marine conditions they may meet. To become certified for advanced diving some technical knowledge is required. Much of this advanced information can be obtained from the plethora of technical books and manuals that are now available and can be found at Scuba.com at great prices.
Organized classes for more complex diving activities are not always required
but are usually helpful. You may need to learn to use more specified life-support
gear as well as new skills needed to successfully complete the dive task. These
skills may point to a need for greater strength and stamina by participating
divers. Unfortunately, most instructors and even the available manuals fail
to stress the necessity of achieving this increased physical strength and stamina.
Course are available which cover a wide range of technical diving certification.
Most training agencies offer these highly specialized programs.
