re: Anyone here have a swing caddie?

I have one. Love it. It's a great tool to have at the range, but its best used at home hitting into a net. I shoot my range finder at the range, and the Swing Caddie is surprisingly close in yardage.

I find it most useful for confirming your yardage gaps, and for wood distances.

The only limitation is that it barely works if the sun is shining directly into it. Aside from that, it gives a reading almost every time.
