This is the brand new Grit X2 Pro from Polar, which is aesthetically my favorite watch from Polar, and it comes with some exciting news. And this news is not just about the Polar Grit X2 Pro itself, but also about the Vantage V3. The reason is that it concerns a firmware update rather than a hardware change, and this firmware update will come to both the Grit X2 Pro and Vantage V3. In fact, the Grit X2 Pro and Vantage V3 are very similar, having identical electronics and software, with the main difference being in housing and design. In this video I will first concisely describe the new Grit X2 Pro and what it can do. After that I will share some details of how this new algorithm works. Now, I am not allowed yet to test it in this video, but of course we will put it to the test once it actually comes out. Finally, I also discussed with Polar why I was getting relatively bad results with the sensor set in the Vantage V3, which is the same as the Grit X2 Pro, and of course today I’ll also share what we found. Plus, I’ll show some more testing of the Vantage V3, including some quick tests on Theresa, since it turns out I might be the problem. So, let’s get started and talk about the new Grit X2 Pro hardware and firmware.

First off, a disclosure, Polar sent me this sample of the Grit X2 Pro for testing, but they did not have any influence on this video or on my opinion, except for some fact-checks I asked them to do. Also, this video will be a bit different from my normal videos, since we are not allowed to do any testing yet. However, what I can do is show you some graph-drawings that represent how the new algorithm will work. And I can also show you some new testing of the Vantage V3, which has the same electronics. Finally I can share what Polar said when I shared my V3 data with them. However, first, since the Grit X2 Pro was just announced, let me briefly share the 10 most important things to know about the Grit X2 Pro!

Polar is set to release two distinct models within its Grit X2 Pro series: the standard Polar Grit X2 Pro in night black and stone gray, and the premium Polar Grit X2 Pro Titan. The main differences between these models are in materials and aesthetics.
