The answer to this question is yes and no, depending on how you plan to use it. You can use the launch monitor without a subscription. The Approach R10 does not require a subscription to function as a basic distance-measuring device. It will provide accurate distance measurements to various targets on the golf course without any ongoing fees. However, it's worth noting that some additional features, such as slope adjustment or certain course mapping updates, may be available through a subscription service provided by Garmin. These optional features may require a subscription or one-time purchase, but they are not necessary for the basic functionality of the device.
