Izzo - rangefinder? I thought you were talking about the finest college basketball coach in the country.
I, too, gave up on sky caddie. Pain in the but to pay for, update, remember to charge, and then to have it with you.
I liked how SkyCaddie showed front - back of green distances.
I switched to Bushnell, really like it. Mine has the "slope" adjustment which, while illegal in tournaments, is very helpful for everyday play on the hilly courses I play.
The tour players caddies I walked with in the Hyundai TOC heartily endorsed the "slope" rangefinders in their practice rounds/course charting.
In theory, there's no difference between theory and practice. In practice, there is. YB
