GPS measurement


GPS integration allows the iD.TRI to offer the highest accuracy with the lowest power consumption. Parameters such as speed and distance are recorded precisely and efficiently with GPS.

3-axis compass


With the integrated compass, you can accurately determine your current position. The compass works along side your GPS signal, so that the direction of movement is correctly aligned even when stationary or with a weak GPS signal. This allows you to orient yourself with the compass anywhere in the world.

                    altitude measurement

Barometric altitude

The altitude is precisely determined by barometric air pressure .The iD.TRI can measure the altitude as well as the temperature.

Acceleration sensor


The integrated acceleration sensor can measure your steps, distance, cadence, sleep phase, and swimming style. When you turn the GPS off, your speed and distance will be determined by the sensor.

External sensors


Do you need more data or higher accuracy for your values? Thanks to ANT+ and Bluetooth (BLE), external sensors for power, speed, heart rate, and cadence can be connected.


Thanks to Bluetooth Smart (BLE), ANT+, and USB interface, the iD.TRI can be paired with your smart phone, PC/MAC, external sensors, and 3rd party apps such as Komoot.
