The SkyCaddie SX400 is a golf GPS device that comes with pre-loaded golf course maps, and it requires a subscription to access additional features such as on-demand course updates and advanced scoring and tracking.
While you can use the SX400 without a subscription, the device will still function as a basic GPS rangefinder, showing you distances to the front, middle, and back of the green. However, you won’t have access to some of the more advanced features, such as the ability to track your shot distances or view detailed hole layouts.
If you plan to use the SkyCaddie SX400 for basic distance measurements, you can use it without a subscription. However, if you want access to the full range of features, you will need to purchase a subscription.
