  • alguien tiene el valor de C2 ?? o las características de C2 para reparar esa pieza. agradezco cualquier ayuda

  • Friends, please help with advice. I have Karma and Nel Thunder coils for Fisher F5, F11,22,44, GoldBug. For meaningful use one of the coils, I bought a Fisher Gold Bug Pro(REV4) control unit. When testing in the apartment, both coils have the same problem with a silver coin 7.8g, diameter 29mm. The sound signal is creaking, intermittent, only in the immediate vicinity of the coils and rather along the edges. ID jumps in different values. Paradoxically, it uncompromisingly detects a different silver coin weighing 2.2g and 21mm in diameter with an accurate sound signal and ID, as well the objects from other metals. Do you think the control unit is faulty?

  • I am new to this, I got a gold bug pro online. Turned it on when it came and it seemed fine, put it away and a month later turned it on to use and nothing happened. I replaced the battery and still nothing. Any idea as what I should do with it?

    • Hi. We will got retire rather than got answer here. Try disassembling the unit, it’s just three screws. It is possible that one of the wires tore off from battery contacts when was handling with the battery.
