Founded in 1936, Sonoto is a Finnish national treasure brand that is a leading manufacturer of many outdoor sports. Revered by consumers for its precision, reliability and stylish design, Suunto wrist computers were used by the Finnish army during World War II to orient themselves in the snow and ice and produce the world's best compass. Its Ambit series integrates a variety of sensors such as GPS, heart rate, altimeter, barometer, and some models also have sapphire crystals, which are very comprehensive and stylish. The new and improved heart rate belt supports underwater heart rate recording, and you can also use the official app to record the exercise track, and generate 3D geographic videos for display and collection, which is convenient and interesting.
