Did the clock previously ordered and also Garmin tried. After intensive use now my conclusion. Have (S625X) and only used for swimming or for competitions since 2006. Polar (The clock keeps still and the testimony by dozens of triathlons and training of quality!) Since my Garmin Forerunner was Globig and not with the new operating system keep up (Windows) and the customer service is not berauchend, I allowed myself the RCX5 Multi, also to the open water again to have accurate distances. In the clock even though no GPS is integrated, but that does not matter because there are possibilities manigfaltige the light sensor while running, biking and (waterproof packed) while swimming in open waters carry. The accuracy I have compared with my Garmin clock and also to the sensor from the wheel, all 100% OK almost the same distances, only a slight deviation of a few meters and not between the clock and the Garmin RCX5, no between the wheel sensor of Polar and RCX5. With the elevation data I had at the beginning a little trouble, but was able to integrate the data yet. The reception in the forest, dense foliage, is 1A. Especially good I liked that even small dirt roads are displayed on the map and is an exact distance also displayed here. That was my Garmin so not offer. The battery from the GPS transmitter stops long enough. The clock is nice and flat and looks good. The training data can be read online or save at Polar. Here I had at the beginning a little concern because it usually yes no concerns when, how much and where I am traveling, but is ok. A separate analysis software would be desirable. What is is a small disadvantage that the clock actually admits low beeps. When there once trained a tempo run or interval and do not know where the kilometers are about, then you really have to look at the clock when you do not want to walk too much. Onst you can not hear the faint beep in the heat of the moment. Otherwise, I am very satisfied with the clock. As always a quality product from Polar. I can only recommend.
