Query: Everything you'd expect

Many times you buy a new technology device and find it doesn't measure (no pun) up. This device is very accurate and is a tremendous time saver. It is what the army would call a "force multiplyer".As with the other recommnedation, I would also like to see a wrist strap and a level (although I'm sure they can both be improvised). Since it takes measurments fast you find yourself spending most of your time juggling between writing and measuring.
