thanx for taking the time to type out that answer/reply. Good inputs that I/we are glad to know your in-field comparisons. Everything you're saying is true. But to my recollection, he tried (or so he said, or so I thought), all the available options. I do recall him getting back home after the "spanking". And he studied forums, instruction manuals, and other more-experienced user's inputs . And he emailed me to say "I should have done such & such" (as if he hadn't exhausted his options).
Based on what you are saying, that is true. It's just that at the time, it sounded like a case of sour grapes, or excuses. But after reading what you're saying, I'll keep my mind open on it
The Minelab Exp. II that I was using, as you know, is NOT meant/known for being a ghost-townsy-iron see through machine. On the contrary: It's in the deep-seeker class with TID wonders as its class (for things like turf cherry picking, where it excels). But given the power-house at is , I still find it to be sufficient for *some* ghost-townsy stuff. Yes , not as killer as specialty machines for seeing a coin behind a nail or two.
HOWEVER, the guy using the 305 with small HF coil was blowing us away ! I've had multiple other iron-see-through machines tested at this site (various 2-filter Tesoros, Compass 77b, Compass auto legend, Racer, etc....), and this guy with the 305 + HF was getting easy target after easy target ! Pistol balls, little pieces of lead and copper snippets, etc..... Granted: His depth was probably not astounding (a "given" for such machines that are going to tend to un-mask). So impressed was I, that I ran out and bought a 705 and small HF coil. Thinking that this is basically the same as his 305 with HF. I was never able to replicate this feat.
Anyhow, thanx again for taking the time to type out the reply !
