I like from 3-7 tones . In my head those provide me with enough information to decide whether to dig or not. Usually one tone depending on detector model makes me dig everything because I think it is something good . And that’s not good in the trashy parks I hunt. I click with the 7 tones on my mxt pro . I like 5 tones on my Deus . Can’t handle more than that . Vanquish good with 5 tones . Apex good . V3i not so much. Xlt not so much . Mx7 good . My experience and my likes . Not associated with any tests just my personal likes
