Took it down to the beach and worked the Golden for a couple of hours. I noticed I was not getting any signals. Went to all metal no threshold. Turned it up and down nothing. Then it would get intermittent. Don't matter one way or the other still no depth. Put my 4" back on still nothing. I boxed it up and sent it with 3 coils to big "T" Town in Prescott today. Probably won't get it back till after Christmas. Like having a friend missing. I miss it already. Great little trash and iron machine. Later Jerry aka Tinfoil
