I had a Bushnell Phantom that worked great, but I stupidly left it stuck (magnetized) to a golf cart and of course it was gone when I went back a half hour later. So, I decided to try this Garmin. OK, it's accurate enough, and the battery charge lasts through 2-3 rounds. But it's harder to use than the Bushnell (more pushing of tiny little buttons to find what I need to know), and the damn proprietary USB charging cable means that I have to drag the cable around with it ALL THE TIME. Couldn't Garmin use a simple micro-USB like everyone else? Nooooo, that would be too easy.
