Suunto Vertical Solar vs COROS VERTIX 2S

For battery life and GPS tracking, the COROS VERTIX 2S comes out ahead with an impressive 118 hours in standard GPS mode compared to 85 hours for the Suunto Vertical Solar. If you’re planning long hikes or adventures, that extra time is a game-changer. In real-world use, the Suunto Vertical Solar shines with its solar charging capability, extending its life up to 60 days in daily mode. However, if you prioritize features like music storage and a next-gen heart rate sensor, the COROS VERTIX 2S is worth considering, especially with its robust 32GB storage for both maps and music.
