YUPITERU Golf Swing Trainer GST-3A I am selling this because I have obtained the data I wanted. Data can be imported to a computer using an SD card. It is battery-powered, so there is no need to worry about battery leakage or degradation. The instruction manual can be downloaded from the official website. It has been used a few days ago, so the operation has been confirmed. A film is attached to the LCD screen, so the screen is clean. It is slightly lifted, but it does not peel off and does not interfere with use at all. Please remove it if you don't need it. Please purchase with the understanding that this is a used item. Also, there is no need for a pedestal. It might be convenient if the height difference exceeds 5 cm. I will basically ship within 24 hours (ship in the morning).
