Suunto Chest Strap
Score: 87/100
Amazfit Active 2
Score: 83/100Rankings
The Suunto Smart Heart Rate Belt is a chest-strap monitor offering ECG-grade accuracy and an industry-leading 500-hour battery life. Its main trade-offs are a short 3-meter transmission range and the lack of an on-strap display. Best suited for multisport athletes who already use Suunto devices.
The Amazfit Active 2 Premium is a round stainless-steel smartwatch with a sapphire-protected AMOLED screen and 10-12 days of battery endurance. It lacks an included USB-C charger and can suffer intermittent Bluetooth drops. Best suited for style-conscious users who value premium materials and dual-frequency GPS.
