If you really learn it.
I've informally competed with a 350 against a Pro. 350 with 5x8 and the pro with the larger stock coil.
A trashy site. A bottom of sorts to it mostly within a foot. Best recoveries on or near that bottom which seemed out of reach for both to be real sure on small coins, with again an edge to the Pro.
The other detectorist I will claim was a better one than I am.
The Pro had an edge overall it seemed and resulted in finds I did not recover. But then ,I made recoveries the Pro did not. A tough site with iffy type i.d challenges at depth below around several inches. ( soil moisture was great ,allowing deeper than usual depth..)
More " hints" than hard i.d. ' s had me wanting to try a V.D.I.. but..not sure at max depth it would have given a much greater edge(?).
I'd be tempted to trade a 350 plus some money for a Pro . Not sure how much money.......though it seems a decent upgrade , more of an upgrade when owning a 350 already is tempting.
