There's another gem on page 15-the digital angle finding level.
While I don't own that unit,it's much the same as my Smartool level,which I've had for a couple of years . The Smartool goes for about $100.00,the Craftsman is $20.00 to members.The audible tones at level,45 degrees and plumb make this tool very handy for any leveling task,particularly if you're working by yourself.
