The Dash can store up to 14 total sensors, with a maximum of 10 ANT+ sensors and 4 Bluetooth LE sensors. Within each activity profile, up to 5 sensors can be used at one time. We recommend spreading our sensors among different activity profiles for various bike equipment and activity types in order to ensure you're able to connect all your sensors at once. If you are not using a sensor regularly, you can also remove it from the Dash by going to Main Menu > Activity Sensors > Select sensor > Delete Sensor. 

Note: Remove Sensor will remove the sensor from the activity profile, while Delete Sensor will remove it from the Dash completely.
