← Scuba: the full card All Knowledge tools →

How this list is made: the words Scuba is described with (what it does, for whom, what it is used for) are matched against every tool in the Atlas. A tool on the same shelf, or doing the same kind of work, counts for a little more. Nothing here is paid for.
