Lasers, lumpy grips, weird apparatuses that lie on the ground, even stranger contraptions hovering around the player's head -- if there's something wrong with your swing, odds are someone's come up with a gadget to try and fix it.

Thing is, all you really need is a household item or two and you'll be all set.

Take that full-length mirror in your closet. You like it because it's an easy way to check yourself out, make sure that suit you bought at Macy's really does fit right. But it's also a great tool for the golf swing, a quick and easy way to make sure you've got the right setup, the key to hitting shots that don't veer off in all directions.

So just how can a mirror help? That's where Tim Mitchell comes in.

An instructor at the David Leadbetter Academy at Red Sky Golf Club in Colorado's Vail Valley, Mitchell shows you why a mirror is useful for more than just preening in this week's video lesson.

Check it -- and yourself -- out.
