As others have said, the Etrac is the better machine over the SE. It's like the V3i to the DFX. Both the Etrac and V3i are very capable and I would say equal machines, but each depend upon the operator to maximuze their potential. For a White's user, the Etrac will have a steep learning curve, the target sounds are different, FeCo numbers vs VDI and icons, depth bars vs numerical depth reading. For a Minelab user, the White's will have a learning curve. If you're buying a Minelab, don't bother with the SE, just get the top of the line Etrac.
