Explorer SE is one of the BEST detectors in the world; however,........ the easiest way to determine if the F-75/T-2 will "trump" the SE...... is to go relic hunting in a iron nail infested site and remove ALL non-ferrous (not iron) targets out of the ground with the SE. Then see if the F-75/T-2 (configured properly) can find any more non-ferrous targets in that exact same area. IF, IF, IF you have time............ read the article: "Head-To-Head Comparison Testing" on the main page of this web-site..............,,,,,,,,,,,,, assuming you have not read it already.
