I bought an Edge 130 as a future replacement to my Edge 510 which I am anticipating die off me soon (rubber covering of power button gone, covered with duct tape only yet still working)
I immediately noticed something weird with the 130 when I am going up slope. Its not responsive at the start, then will suddenly shoot up to percentages beyond Zoncolan then just as quickly goes down to normalize
I did a video showing differences between the FIT files of 130 vs the 510, Fenix 3, and the Virb X, and it shows as if I am hitting a wall on the 130. Maybe I need to bring a ladder next time.
