My wife has surprised me by planning to build a putting green and an outdoor driving range in our backyard. I purchased the Spornia Spg-8 Golf Practice Net yesterday and tested it with the Garmin R10; it worked flawlessly for what I needed it to do. FYI: I'm not using the driving range mode, just the HTH mode, and it's a lot of fun. I can't wait for my backyard to be finished so I won't have to hit off dirt any longer.
