Shaw uses a handheld device to perform a real-time carbon dating on an alien cadaver. This device is a cylinder with thick-gauged needle. White rings around the base and a big button on its side indicate power. When pressed into the alien tissue, the date appears on a small screen along its side along with four beeps. Shaw then turns it off with the press of the button.
Though the device has a very little screen time, it seems simple to use, suited to purpose, and with nothing extraneous. A simple device that as far as we see is well done.
