Grit X

Het kan wel enorm verschillen, althans wel bij mij. Ik heb door de jaren heen een aantal inspanningstesten gedaan bij de sportarts in het ziekenhuis. Dat is uiteraard met professionele apparatuur. Ter vergelijking heb ik dit naast een aantal horloges en hartslagbanden gehouden. Puur uit interesse. D

I had the Fenix 7 Pro and sold it for the Polar Grit X2 Pro. Reason: simplicity. Polar gives me exactly what I need without unnecessary features. The HRV/Orthostatic test with the H10 is accurate and useful for training decisions. With Garmin I always felt overwhelmed by functions I didn’t use. Also

I recommend Polar Grit X Pro if you liked the Grit X and the Polar ecosystem. It is still available if you look around. I had the original Grit X and had the pressure sensor replaced 3 times within warranty including change of back cover that was supposed to solve the problem with height measurement

Excellent choice. I have the Polar Grit X2 Pro. Excellent brand. Very good quality. This is the brand with the best data accuracy 📈 heart and sleep. I use the Polar H10 only in cycling and VMA or vameval test mode (in France 🇫🇷). I wish you lots of fun in your outings 😃

Polar Grit X Pro: 4 years, daily use. The sensor started to get unreliable, the screen got dimmer, some buttons started to stick... It was just time to retire the watch.

I think a useful feature for me would be Climbpro - and I see Suunto has Climb Guidance. Does that effectively mean the following tradeoffs - or is there anything I'm missing? Thanks - Suunto Vertical 2 titanium - best battery (by some distance), Climb Guidance, ok app/mapping, potential data privac

I thought true HRV is the time between heartbeats, averaged? R-R interval? Can't an ECG chest measure this quite accurately? If there are continuous heart measurements throughout sleep and then averaged, I think this is a very reasonable basis to test a wearable accuracy. It's the whole basis for th

I watched his video last night. The value that the Helio Strap brings is incredible, as is the heart rate tracking. It really is so, SO good especially when worn on the bicep. I ran into the same issue he did with the step counting inaccuracy though. I have done multiple 10,000 step days as well as

It is sad. As I read here, several outdoor runs are needed with a Polar watch to calibrate it using GNSS signals. Manual: > Your watch measures speed and distance from your wrist movements with a built-in accelerometer. This feature comes in handy when running indoors or in places with limited GPS s

Edit: I just own the watch two days. Today I went for a run and it felt way off. My good old Polar Grit X, which is old, but has a good heartrate sensor, showed me 20+ more than the Suunto. On a 10KM run the Suunto said I burned 498 Kcal, while my Polar says 972 Kcal. 498 can't be right.
