I didn't believe it myself until I saw it at the Sports Authority, but there is a device for picking up golf balls called a Golf Ball Shagger. The idea behind this device is it allows you to pick up lots of golf balls without getting a sore back from bending over. This device is a metal-frame-reinforced cylinder-shaped bag with a handle on top and a retractable metal pipe on the bottom. You "shag" golf balls by walking with this device and placing the pipe on a golf ball. The end of the pipe has small metal clips that only allow golf balls to pass one way, so they can't fall back out. Eventually, the bag gets full or you run out of golf balls to pick up. To empty the device, you simply unzip the bag.
