They also have a long history of making diving instruments and dive computers. Thus the Suunto Wristop Computer line of outdoor instruments was born. On the top of that those Wristop Computers are loaded with different logging systems and ways of reading the accumulated data making them useful in analysing the climb and providing a means of giving proof to claims of summiting, just to give an example. The barometer is a must-have instrument in predicting the weather and finding the optimum window for summit attempts. Suunto supplied the expedition team with Suunto AdVizor and Vector Wristop Computers.
Vector includes a sports watch, barometer, altimeter, thermometer and compass.
AdVizor adds to this a Polar heart rate monitor. It also provides slightly more accurate readings, maximum altitude resolution is one meter. All the down is sourced from Arctic Siberia, where the animals grow to maturity. All Joutsen down is at least 750 fill power and so clean that it does not cause allergic reactions due to the impurities present in low quality down products. Veikka would have come with us if the Annapurna gig had not been on the way.
