How does the Sniffer work?

Much obliged

When it's blue, it's set to stains. The faster it beeps, the closer you are to stains.
Green works the same way except instead of detecting stains, it detects debris such as gibs and garbage.

Thank you!

Blue is organics; blood and guts and goo.

Green is inorganics; trash, bullet holes, soot, etc.

Some small items and nearly cleaned splatters have very weak "signals" and the sniffer won't react noticibly unless you're really close to them. Larger messes can be detected halfway across the map (or so it seems sometimes). With practice you'll be able to tell the *very* subtle difference between "clean" and "there's one tiny bit of something nearby"
