| Can connect with your sports watch, cycle computer or fitness equipment via Bluetooth, ANT+ or 5kHz. |
| Can connect with a Bluetooth and ANT+ device at the same time; this is ideal when you exercise with multiple devices such as a cycle computer and sports watch. |
| Receive real-time heart rate data on your favourite training devices. |
| A heart rate monitor with the accuracy that is characteristic of Garmin. |
| A very long battery life: 3.5 years at an average use of 1 hour per day. |
| Can connect with most bike computers and smartphones via Bluetooth and ANT+. |
| Viiiiva can be used as an ANT+ bridge to Apple TV and other Apple devices. |
| Highly accurate heart rate recording with the optimised heart rate measurement system. |
| Data can be collected easily from ANT+ sensors and exchanged with your smartphone via Bluetooth. |
| Thanks to its good memory, the Viiiiva can store up to 65 hours of training data. |
| Runs up to 200 hours on one CR2032 coin cell battery. |
Cons
| The Polar H9 has no memory function or accelerometer. For these features please consider the Polar H10 heart rate sensor. |

| This product uses a replaceable coin cell battery and is, therefore, not rechargeable. |
