You can start with Arccos Air and add Smart Sensors at any time. Once sensors are added to your account, you can switch to sensor-based tracking for future rounds while continuing to use the same Arccos membership and app. Read more about this here.
Arccos Air is compatible with 2nd, 3rd, and 4th generation Arccos sensors, including full sets, Arccos Smart Sensors, Smart Grips, Cobra CONNECT, and PING Smart Sets.
