The QUICK-FIX Scanner is a sesnsory device and your only hope to collect data ingame. The device transforms into a compact storage mode and is worn on the wrist. One member says its better than any current diagnostic equipment. It projects a scanning field around the target that looks like a rectangular prisim. It is mostly used by hazmat teams, but not by anybody else ingame.
A quick introduction in in how the hazmat suit's scanner works -- when you approach a secret or in some proximity to it, the scanning bar appears and you hear the distinct whine of the meter go off. As you approach the secret's location the bar turns from green to red. When the bar is at its limit, the secret is literally "right next to you".
