How much more depth F75 vs Whites MXT

[pvtcook]

Ok guys I sold my MXT and am within a frogs hair of buying the F75 limited.I was just wondering how much more depth I can expect out of the F75. I hunt relics only.
Thanks

All I can tell you is the manual of the F-75 clearly states, and I quote: "The F-75 can detect U.S. coins to a depth of up to 15-16 inches under good conditions."

Now, how well it does...I dont know, and what is required for good conditions I dont know.
