OK folks new to this forum, and would like some ideas....I have a gtax1000 I guess it is 10 or more years old, I am just getting interested in using it again after a long layoff . Is this machine up to today's standards ,and can new coils be added to it.. took it out yesterday at an old horse farm in middle Virginia and found a dollar or more in one hole,60's vintage coins, and wheat pennies.kind of have the bug again to hunt ,living in Va beach , I have not really ever hunted the beach much, but will probably start...any Ideas will be appreciated..
