What I have heard is that the F75/T2 is a great relic machine, especially in Southern red soils. Build quality is a little crappy on the 75. I think to answer the question fairly, you need to let us know what kind of hunting you're doing (relics, old coins, new coins, jewelry, etc.) and what area of the country you are in. If you are seeking Civil War relics in the Southern US, the F75 is getting great results. If you're seeing old coins in New England or the Midwest, the E-Trac or Explorer is a great machine. If you're looking for modern clad any machine will do, so don't waste your money on a top of the line machine, it's overkill. The Minelab X-Terra series is an excellent all-around machine, as are most mid-range machines from White's, Fisher, Tesoro, and Garrett. If you're looking for jewelry/gold, get a machine that has a good reputation for gold. I believe the new V3 may have a real edge for gold, but I have yet to see this for myself or in anyone else's results.
