DFX is a good relic hunting machine.
I used to be a White's dealer and while it isn't THE deepest machine, it does a good job.
I've found some deep stuff with it, both ferrous and non-ferrous. I could tell a difference between fairly large pieces of iron and cannonball fragments by the noise and location on the meter. The key is to know your machine and what it tells you.
DFX...If you want to find coins, set it up to pick up the lower frequency. If you want the stuff located on the lower end of your meter's numeric scale, go with the higher frequency.
Mixed mode is ok, if you are searching to find out what kind on metals are mostly in the area you're hunting. Once you get an indication to the majority of the targets in an area, switched to that frequency.
Remember too:
Just like with any machine, the soil, atmospheric and mental conditions make a big difference. And, no matter how well you know your machine, you'll dig some junk, becasue some junk sounds like the good targets.
