I would like to revive this topic, it's very interesting I always run horseshoe on ,but have never investigated the targets that gave a vdi of minius.
That's not to say I haven't dug gold that started as a minus number.when detecting in highly mineralised sand a target can have 90% ferrous 10% non ferrous sound..
I would like to know what advantages you feel 1 tone is over 50,I will be trying 1 tone,for the next week of hunting.
It's possible 1 tone will give a cleaner sound to a deep non ferrous target.did it take a while to adjust to 1 tone..thanks
