Review on Smart watch SUUNTO Spartan Trainer wrist HR, ocean by Janis Libeks ᠌

- Heart rate monitor. To say that the optical heart rate monitor is lying is to compliment him. He doesn't just lie by 10-15%, as I might expect. He draws data from the astral plane. I went up the hill with a length of 150 meters, I decided to measure the pulse. 110, the watch confidently told me. After 5 minutes, I was walking on a flat road and they already told me that my heart rate was 170. In short sprints, they sometimes say that my heart rate reaches 210, despite the fact that on the chest strap I have never seen a heart rate above 195. When I first bought them, during training I checked the accuracy of the data on the Ambit2S from the belt and on the Spartans from the optical sensor. For 75-80 minutes of training, the Spartans showed 10 strokes higher. There were times when Ambit showed a pulse of 120, and Spartans - 180. The same parsley was today, when after a warm-up he stood, and the pulse showed - 155. While jogging, I measured on the carotid artery - 140, by the clock - 185. In short, With this heart rate monitor, it is impossible to determine the pulse, even the pulse zones. He can easily lie for 40-50 punches. If you can understand from the schedule from the chest strap how many intervals a person ran, it is clearly visible there when the pulse rises, when it falls, on the optics - a solid mess. It is worth noting that this is not the problem of this watch. I heard similar reviews from the owners of Garmin Fenix ​​5. - For watches that in the 2022 officially cost from 20k, they look like a children's Chinese watch for 300. True, I compared them with Ambit3S, the material is the same.
