I don't know why people always want to dig deep ! Digging a foot deep or deeper on every signal would be very tiring on a full days detecting, plus your finds rate would drop off as you spend 15 minutes plus digging and replacing a foot deep hole just to find a bit of lead or rusty iron, give me separation, recovery, sensitivity and good ground balance any day over depth, or the kind of depth people always seem to want ! Can you imagine the mess you will make digging a 20" hole on pasture just for a ring pull or bit of rusty, ok there will be the odd find worth the time and effort of digging 2 foot but not enough for me to waste time and energy, but each to their own, if your happy to and fit enough then crack on lol
