Thank you for viewing. I used this as a supplement because the characters on watch-type devices are too small to read. I am selling it because I have upgraded to a Garmin G80. It's like new, with a usage period of about 10 rounds. Thank you. - Model Name: Shot Navi Granz - Function: Golf GPS Navigation - Country of Manufacture: Japan - Accessories: USB cable, box, instruction manual Thank you for viewing.
