  • Hence why the performance will be very similar to the old Garrett range…

    • No they are a lot better, faster reponse, better iron recovery, nicer tones, great machines for the money IMHO

  • Took my old gta 1000 out of wraps. It operated ok for a day or two. But now when I press buttons they fail to work, so can’t go detecting. Can I lubricate the buttons with anything to make them work, or are the circuit boards jiggered?

  • Hi, I’m looking for a Garrett Ace 300i or upgrade motherboard replacement because my existing one was damaged when a battery leaked and destroyed the board.
