White’s GoldMaster GMT Metal Detector

  • Description

    The GMT is White’s “Goldmaster” — used in goldfields around the world! This detector ignores the harsh ground found in gold-bearing areas to simplify prospecting and find nuggets large and small, and coins, too.

    The GMT is made for gold country, with 48 KHz operating frequency — the best for gold — and a waterproof search coil that’s ready for streams and rivers.

    High-end features like the iron target analyzer make hunting easier. Manual controls are available for advanced users, and each option includes a recommended initial setting.

    Also onboard: variable self-adjusting threshold, Grab Pushpad for setting ground balance instantly, automatic ground balance, and “Follow the Paystreak” feature, which displays the amount of magnetic minerals in the ground.
