The White's Goldmaster GMT metal detector was introduced in 2000 and was still in production when White’s closed up shop in 2020. It is a 48 khz induction balance metal detector aimed primarily at gold prospecting.
"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."
