Suunto Oy is a company that manufactures and markets sports watches, dive computers and precision instruments. Headquartered in Vantaa, Finland, Suunto employs more than 400 people worldwide, and its products are sold in over 100 countries. Although globally active the factory is placed next to the HQ, where most of the work stages are still handcraft. Suunto is a subsidiary of Amer Sports Corporation with sister brands Wilson, Atomic, Salomon, Precor, Arc'teryx and Mavic.

History[edit]

In 1933 the company's founder, Tuomas Vohlonen, a surveyor by profession, applied for a patent for a unique method of filling and sealing a lightweight compass housing made entirely of celluloid with liquid to dampen the needle and protect it from shock and wear due to excessive motion.[1] In 1935, Volhonen was granted a patent on his design, which went into mass production a year later as the wrist-mount M-311.[1] Though it was not the first portable liquid-filled compass, Vohlonen's design was compact and lighweight, enabling it to be easily worn on the wrist.[2][3][4][5][6]

During World War II, Suunto introduced a compact liquid sighting compass, the M/40, during World War II for artillery officers and other users needing a precision instrument for measuring an azimuth. The company grew rapidly after World War II, supplying compasses and other navigational instruments to both civilian and military markets. After Tuomas Vohlonen's death in 1939, his wife Elli Vohlonen operated Suunto Oy until 1952.

In 1996, Suunto Oy acquired Recta SA, a Swiss compass manufacturer. Suunto Oy was in turn acquired by Amer Sports Group in 1999, which now owns both companies.

Compass products[edit]

Suunto M-311 compass from 1930's

Suunto makes a wide variety of magnetic compasses, including the A and M series for general navigation, the Arrow series of compasses for competitive orienteering the KB, MB and MC line for those requiring a professional-quality hand bearing compass.[7] Suunto also produces the Recta line of compasses, including the new DT baseplate series based on Suunto designs, the DS series of mirror sighting compasses, the Recta Clipper micro compasses, and the famous DP 'matchbox' series of military compasses invented by Recta in 1941. The Recta DP-6 is still used by the Swiss Army. In 2009, Suunto discontinued the Swiss-made Recta DO series, moving all remaining Recta compass production from Biel, Switzerland to its production facility in Vantaa, Finland.[8]

After acquiring Recta AG in 1996, Suunto incorporated the Recta Turbo 20 global needle system technology originally patented by Recta SA[9][10] into many of its own compass designs, such as the Suunto M-3G (Global) Leader and the MC-2G (Global) Navigator. These 'Global' compasses have proprietary needles that can operate accurately in all world magnetic zones.[11] The construction also results in an unusually stable needle that even works with the compass tilted up to 20 degrees.[11] The company also continues to refine its line of outdoor and orienteering compasses with features such as improved luminosity, adjustable declination, and fast-settling needle designs and more durable materials.

Since 1967, Suunto has offered its KB line of high-quality hand-bearing surveying compasses and inclinometers that are accurate to fractions of a degree. These compasses are popular among cave explorers, foresters, geologists, archaeologists, land surveyors, dish and PV element site survayors and mariners. Traditionally made of a solid block of machined aluminum (some newer versions are in high-impact plastic housings), each KB compass contains a magnetized dial with calibration markings printed along its outer edge.[12] A magnifying lens (KB-14) or prismatic sight (KB-77) is mounted at one end of the instrument with a crosshair providing a view of the disc, containing both forward and reciprocal bearings.[12] In operation, the user divides his or her field of vision with the instrument, using the device's lens or prism to precisely measure the bearing of the object in view.[12]

Global Needle System[edit]

The Suunto Global Needle System acquired from Recta as the Turbo-20 needle design, the conventional magnetized compass needle is not used.[9][11][13] Instead, the compass needle and magnet are built as separate units functioning independently from each other.[11][13] The needle itself is fixed at its pivot by means of a double bearing, while the magnet rotates on a pivot with its own jeweled bearing.[11] When attracted by the earth's magnetic field, the separate compass magnet absorbs the vertical force of the magnetic field, so that the inclination angle of the magnetic field (magnetic dip) cannot tilt the needle, and the needle can no longer move in a vertical plane.[11] This provides accurate readings of magnetic north in all magnetic zones of the world. The design also permits accurate readings with the compass tilted at angles of up to 20 degrees,[11] while the use of a strong magnet causes the needle to settle extremely quickly, facilitating fast and accurate bearing/course measurements.[11] This allows a user to obtain fairly accurate compass bearings even when moving, such as when hiking or traveling in a canoe.[11][14] Current Suunto products that incorporate the Global System Needle are the Suunto M-3G and MC-2G, and the Recta models DT420G and DS50G.

Military models[edit]

Recta DP Swiss Army compass

The most popular Suunto compasses used by armed forces around the world are MC-2, KB-14, A-30, M-9 and Clipper. These are sometimes adapted to local requirements. The MC-2 optical-sight (mirror) compass along with several other Suunto compasses has been approved for issue to various NATO military forces, including Canadian Land Forces and several U.S. Special Forces units (the 'T' in the model designation indicates the compass has been fitted with tritium self-illumination).[15]

In addition to its own line of magnetic compasses and other measuring instruments, Suunto continues to produce the DP 'matchbox' compass line, including the original Recta DP-6 for the Swiss Armed Forces.

Wristop computers and heart rate monitors[edit]

Suunto is famed for its multi-function electronic wristwatches such as the Core, Ambit, Vector, X-Lander, and X10, which can provide a variety of functions including compass bearings, acceleration, altitude, training effect and even GPS location, depending on the model. Suunto's multi-function electronic wristops are made for different sports like sailing, golfing, hiking, mountaineering, alpine skiing, training and diving.

Suunto T6 with its later versions T6C (=Comfort belt) and T6D (=Dual belt) was one of the most advanced among heart rate monitors at the time of its release in 2004. It has, among other features, rate-to-rate recording of heart rate, an altimeter based on air pressure, calculation of EPOC and training effect and support for external POD devices measuring speed and distance.

Suunto T3 (and its C and D versions) offered many advanced training properties with much lower price than T6. Especially the support of POD devices was rarely found in its price category. The T4 (with also C and D versions) was close the same as the T3, but it added an electronic coach function. There was also a T1, a very basic heart monitor in T-series. All T-series versions are out of production until 2012.

The M-series is a successor of T-series (except for T6). The M-series is more of a fitness lineup, while T-series was aimed more at sports training. The M-series include the basic heart monitors M1 and M2 (same watch, different heart rate strap) and M4 and M5 with more advanced functions, most of which electronic coaching for specific goals, such as losing weight or improving physical performance. M4 has gone out of production until 2013.

Suunto Quest is a heart rate monitor aimed at sports training. It has many training functions and an electronic coach function.

Suunto Ambit, released in 2012, is currently the most advanced of Suunto wristops. It includes GPS, ABC-functions, rechargeable battery, advanced training functions (in training functions Ambit is a successor of T6) and updatable software. User can modify many of the functions of Ambit according to individual preferences. Different apps are also available for Ambit, and users can also create their own apps. The Ambit family was updated in 2013 with top version Ambit2 and added with the Ambit2 S. In 2014 Ambit2 R was introduced. Ambit2 S and Ambit2 R appear with fewer functions compared to Ambit2.

Suunto Core is an ABC-watch (A=altitude, B=barometer, C=compass). Since its release in 2007 there has been more than 25 different versions of Core. All of them have the same functions, but their external appearance differ. Most versions have plastic frames, but some are made of aluminum and two of them are made of stainless steel. Most of the Core versions are no longer in production. There are some limited, numbered editions of Core, such as Everest Edition (8848 made, in honor of Apa Sherpa's 21 ascents on Mount Everest), Red Bull X-Alps Edition (864 made, according to the length of the race), and Extreme Edition (3000 made). Suunto celebrated its 75th anniversary by releasing Anniversary Edition (in some countries known as Alpine edition). Core All Black is often erroneously referred to as Core All Black Military or Core Military, but such nominations are not official and such "military" versions don't exist.

Suunto also manufactures the Elementum series of premium wristwatches with some specialized functions for outdoor (Terra), sailing (Ventus) and water activities (Aqua).

Suunto uses the Suunto ANT and ANT+ (based on the ANT network standard) protocols in wireless transmission of data, except for some basic models, which use analog signal.

Suunto also provides software for interpreting recorded data from wristops and HRM's and for controlling them. In the beginning of 2010 Suunto released Movescount online service. Before that the data could be handled for example through Training Manager (for T6), Training Manager Lite (for other T-series) and through specialized diving software.

Diving computers and instruments[edit]

In 1965, a British sport diver noticed that Suunto’s liquid filled compass also worked underwater. Following this revelation, it didn’t take long before Suunto’s first dive compass (SK-4) was launched and become well known for its durability and reliability. Among the users were explorers, ecologists and famous sea-dwellers like Jacques Cousteau. During the 1980s, Suunto became the world leader in the manufacturing of diving instruments. Having previously produced mechanical instruments, Suunto now started the production of diving computers and launched the SME in 1987. This was Suunto’s most significant innovation of the decade and a major influence on scuba diving’s transition to a popular sport. As a well-established manufacturer and developer of diving computers and instruments, the company based in Finland continues to innovate.

Suunto was the first to introduce:

Suunto is highly regarded around the world and is used by professionals like the freediver William Trubridge and the underwater explorer Jill Heinerth. Suunto also provides the official measurement instruments for all AIDA freediving world record attempts and World Championships competitions.

The product range of diving computers and instruments falls in:

  • Watch sized: Suunto D4i, D6i, D9tx, DX
  • Large Display: Suunto Zoop, Vyper, Vyper Air, Cobra, Cobra 3, HelO2
  • Instruments: Suunto Cylinder pressure meter, depth gauges and compasses, which can be combined as any kind of Consoles

Suunto in the media[edit]

  • Using Suunto Vector altimeter/compasses and Garmin 60CSx GPS mapping receivers, Australians Nathan Welch and Mark Kalch became the fourth team in history to successfully navigate the entirety of the Amazon River.[16][17][18]
  • The Suunto X10, a wristop GPS receiver, was awarded Best Adventure Gear of 2009 by National Geographic Adventure magazine.
  • On April 4, 2008, Swiss climbers Ueli Steck and Simon Anthamatten made the first ascent of Mt. Tengkampoche's North Face in Nepal using Suunto Core wrist altimeters.[19]
  • Suunto Core has taken the glory in one of the most renowned and hardest-fought international design competitions by winning the "red dot: best of the best" award at the red dot design competition in Germany in 2010.
