Dual Band (Bluetooth & ANT+): Ultimate flexibility. It transmits simultaneously on both protocols, allowing you to connect the strap to your smartphone or tablet (via Bluetooth) and at the same time to your sports watch or bike computer (via ANT+).
Bluetooth: The most common option. Ideal for connecting the strap to your phone (e.g. Strava), your smartwatch, or modern gym equipment.
ANT+: Specialized sports protocol, essential for seamless connection with sports watches (such as Garmin) and bike computers.
Yes (Specially designed for water): Fully waterproof. It stores your heart rate while you swim and sends it to your watch/phone as soon as you get out of the water.
