Brief History of Dive Computers 

It was first used by the Navy for military warfare. SOS was the first brand of dive computer which was introduced to the market. It was designed and developed by two Italian genii, Gallinari and DeSanctis. The main purpose of the device is to serve as a monitor/meter for divers. Unfortunately, the dive computer was not able to accurately calculate the decompression status. 

In 1979, the first digital dive computer was invented. Its design was similar to a cash register. A tube was connected to the diver via a cable, which had a built-in sensor to record the pressure underwater. Head into Wiki for the complete history about Dive computers.

It was also made to be user-friendly, such a way that even beginners could easily adapt. Other brands integrated a sensor within the dive computer, which is advantageous to marine archeologists that regularly dive into the ocean to do research and analysis. 

Dive Watch vs Dive Computer 

Dive computers and dive watch work the same way. It’s just that dive computer is a more technologically advanced compared to the watch. The gauging features of dive computers are more accurate than their counterparts, thus making the former a better option especially for enthusiastic divers. 

Others believe that dive watches could be near its end. The electronic depth sensor of the dive computer is more reliable for diving. Dive computer these days can even monitor temperature, dive time, depth, and can even monitor the amount of air left in a tank. Keeping track of these things can help divers avoid unnecessary accidents and decompression sickness. 

Most diving institutes require the dive computers over its counterparts. The safety features that dive computers offer are essential to all types of divers, especially to beginners.
