Because of the multiple simultaneous frequency mode on the Equinox 800, it may be slower than the Deus. The Equinox 800 has a lot more data to process when operating in multiple frequency mode, so the return time and recovery speed will suffer some. The Deus does not have this problem because it is, essentially, a single frequency metal detector.  It does have multiple frequencies it can operate on, but it can only use one at a time, whereas the Equinox 800 can use its frequencies one at a time or simultaneously.
