As you embrace the joys of being a certified diver, it doesn’t take long before you consider buying your own scuba gear. If you have already invested in basic diving gear such as a mask, fins, and snorkel, the next thing that usually comes to mind is getting a dive computer. Also referred to as a personal decompression computer or decompression meter, this piece of equipment allows you to check real-time dive information such as depth, time, and previous dive info through a display monitor. A dive computer is easy to use and more convenient to bring with you on your dive because it combines the functions of a depth gauge, timer, and sometimes, submersible pressure gauge (SPG).
History of dive computers
You might be surprised to know that the dive computer dates back to the 1950s when the first analog versions were tested by the US Navy. However, it was only in 1983 when the first digital dive computer, capable of displaying the information on a monitor was released by a Swiss manufacturer called Hans Hass DecoBrain. Four years later, the Aladin Pro by UWATEC became a big hit in the market as divers favored the bulky grey box that could easily be strapped on the wrist during a dive. This innovative gadget uses the algorithms based on the theories of Albert Bühlmann, the godfather of decompression theory. By the 1900s, scuba diving became more popular as a leisure activity and more dive centers began offering affordable beginner and professional dive courses. The rising popularity of the sport encouraged manufacturers to come up with more innovative and budget-friendly equipment including dive computers. As the years passed, the dive tables became less and less popular and by 1997, the wrist-strapped dive computers became an essential piece of dive equipment. Many training agencies also adjusted to the changing times by incorporating the use of this equipment in their courses.
