"I've found that the jumpy signals that are good are jumping in a repeatable way in correlation with my swing".
Thank you, I was back to digging nails yesterday, and now that I think about it the good items I recovered had a good mixed with bad and did repeat similar numbers from same direction over and over again,
I now learnt it is a time thing, and you have decide what you can get done in a given amount of time,
pick an area and keep digging any possibility, or keeping over over an area on multiple visit, digging less and less obvious targets each time
also you can switch over to 10 kh to check a signal and if it jump way higher in vdi it has a strong possibility of being iron. so say you are getting a jumpy 10-15 signal, in 10 kh it would jump to like 25 if it iron,
Yes I find this method good back up
Thanks
