Thank you for viewing. No need to confirm beforehand, instant purchase is OK. First come, first served, so please refrain from price negotiations. High-performance golf ball flight measurement device. Compact, easy to set up, and highly accurate. I'm selling it because I no longer need it since an indoor practice facility opened nearby. Like new, with no noticeable scratches. Software is initially updated. By installing the app and registering an account, you can also simulate courses. Please consider purchasing only if you understand that this is a used item.
