Buyer's Guide
Suunto is a Finnish company that was founded in Vantaa, Finland, in 1938. A leader in the measuring instruments industry, Suunto manufactures compasses, precision instruments, sports watches, and dive computers.
The founder of Suunto, Tuomas Vohlonen, named the company based on the meaning of the Finnish word suunta, which means “direction” or “path” and in navigation, ” bearing” or “heading.” The headquarters is still located in Vantaa, Finland, and the company employs over 300 people worldwide. The products are sold in over 100 countries around the world. Suunto is a subsidiary of Amer Sports Corporation.
The first Suunto dive compass was produced in 1965 when a British sport diver realized that Suunto’s liquid-filled compass worked underwater. The famous Jacques Cousteau even wore Suunto’s first dive compass. In the 1980’s Suunto began researching, developing, and launching electronic diving computers and has made a name for themselves on the global stage with their high quality and robust dive computer models.
The Suunto DX is the first of its kind, a wristwatch style dive computer that has the functions to work with rebreathers and for open circuit systems. The Suunto Zoop Novo is one of the most affordable, efficient, and highly reviewed dive computers for entry-level and recreational divers on the market. Many of the Suunto dive computers have the option of wireless air integration by purchasing a wireless transmitter to track air consumption during dives.
