I know of one person who has an F75LTD, a Deus, and an Explorer SE Pro. Here are a few comments that he posted on another forum:
"The Explorer has the edge in high EMI areas followed closely by the Deus and then way down the line, the F75. The Deus is a really good relic detector and is as fast if not faster than the F75 when comparing processing speed. The Minelab Explorer SE Pro on short manicured grass or hardpan is deeper than the Deus, or at least I have not found any settings yet that will equal the Explorer on these conditions. The F75 LTD in Boost mode in tall grass and rough plowed fields will trump both the Explorer and the Deus."
