Dont be worried about using your vallon for gold I have a vallon vmh3cs and it goes deeper and see's smaller gold than my gp3500 or my garrett atx, I dont know about you or anyone else on here but when I'm prospecting I dig every target anyway so discrimination doesnt matter. I've tested these two machines set properly over and over against the vallon and they dont come close. The comments I read about having to use a detector specifically designed to find gold crack me up. I'm anxious to compare it too a gpx5000 to see how close the vallon is in depth.and sensitivity, I think maybe vallon is a name the big $$$ detector people are a little afraid of the vallon is also a hell of alot better built and swings better than any other detector out there as far as I'm concerned, garrett is decent in design and look good but they fall apart especially the shaft configuration is a joke.
