Decompression is covered in detail with examples including deep stops and decompression ceilings, both fixed and variable.The different dive computers sold are covered, including the four basic styles found: wrist computers, console computers, computer watches and mask computers- each with or without air integration options- some are more suited for shallow diving, while others are more suited to deep technical diving. Different functionalities found on modern dive computers and their intended uses are also covered including choosing the best and correct dive computer(s) for your needs, and getting the most of the dive computer(s) you have or choose to buy.
