This mount can be attached to tubing that is 1 inch in diameter or less. It will fit most walking carts and can fit on motorized golf carts roof supports as long as the tubing is 1 inch or less.
The mount has a face plate that accepts button type mounts like the one found on the back of your Garmin Golflogix.
The face plate can be rotated 360 degrees so you can adjust the mount to just about any position to get the best view.
