Scott uses his ring to fly, walk through solid objects by "moving through the fourth dimension", paralyze or blind people temporarily, hypnotize them, create rays of energy, melt metal as with a blowtorch, and cause dangerous objects to glow, among other things. It could also allow him and others to time travel. Occasionally, he uses it to read minds or create solid objects and force fields in the manner usually associated with fellow Green Lantern, Hal Jordan. His ring could protect him against any object made of metal, but would not protect him against any wood- or plant-based objects.
