Summary: I've used this in Ohio, Pennsylvania, Florida, North & South Carolina with no problems at all. It will hold every golf course in the US, and you can download any course revisions at any time. Battery lasts about (3) 18 hole rounds before needing recharged.
Summary: Works very well, great for use in the field for sighting trees, bushes and termite mounds. Very clear display in the sighter. Arrived well ahead of estimated delivery, which was great as I needed it quickly
