Suunto's first dive computer Suunto SME-ML, was launched back in 1987. Still, the company's history goes back over 80 years when Tuomas Vohlonen, adventurer and avid outdoors enthusiast, invented the liquid-filled compass with a highly accurate needle. The new Suunto compass was so reliable that thousands of them were produced and adopted by the Finnish army just in time for the 2 WW, where they were extensively used in the Winter war and earned the catchphrase "Replacing Luck" by its users. 

The first Suunto underwater compass was invented by an accident when in 1965, a British scuba diver took his favourite Suunto SK-4 compass for a dive and discovered that it worked well showing the correct heading underwater . The underwater compass was born. Since the beginning, Suunto instruments have received worldwide recognition for dive instruments that are accurate, well-made and reliable.

Moving to the most recent times, Suunto achieved another milestone by producing a top-of-the-line, multi-lever dive watch-style dive computer in the body of the SUUNTO Spyder. The quality of this first watch-type Suunto dive computer can be seen even today as we receive quite a few Suunto Spyders for regular battery servicing in our Servicing Department - still going strong after all these years.

Suunto Algorithms

Suunto has been developing its latest algorithms with Dr Bruce Wienke for over a decade. The RGBM algorithm (Reduced Gradient Bubble Model) is at the heart of every Suunto Dive Computer. Presently RGBM algorithms are used in Zoop Novo, Wyper Novo, D4i and D6i. In contrast, the more advanced algorithm Suunto Fused™ RGBM, Suunto Fused™ RGBM 2, is used in technical diving computers such as Suunto Eon Core and Suunto EON Steel. But nobody can explain SUUNTO Algorithms like Dr Wienke himself below:


Suunto Entry-Level Dive Computers

Suunto produces reliable, great-value-for-money entry-level dive computers such as Suunto Zoop Novo or Suunto D4i Novo. Both Computers are excellent units if you want a simple-to-use, fully decompression air and nitrox dive computer that uses the standard Suunto RGBM decompression model.The Suunto ZOOP may not have air integration or Bluetooth connection but will do all needs to be done to execute the air and nitrox calculation every single time: 

Suunto Advanced and Extended Range Dive Computers

Suppose you are a beginner scuba diver looking to expand your diving skills further and engage in more advanced and extended-range decompression diving in the future. In that case, you should consider a dive computer that allows managing different breathing gases and multiple tanks underwater. Extended range gas-switching computers:

Suunto Technical Dive Computers

The technical range of Suunto dive computers started with the release of the Suunto HelO2 dive computer - the first dive computer with full open circuit gas capability with the possibility of switching gases underwater, including air, nitrox and trimix. The latest models, such as Suunto EON Core or Suunto EON Steel, employ The Suunto Fused™ RGBM algorithm supporting rebreather capability and  dive down to 150 m.
