White's Goldmaster 4/B Metal Detector - The Goldmaster Series


Goldmaster 4/B

Make the newly designed Goldmaster 4/B your prospecting partner if you're after gold nuggets, big and small. The New GM 4/B's performance is second to none in the extreme mineralization typical of gold-bearing areas.

We have incorporated a new well-balanced body design with new technological features including the ERS (Electronic Ramping Systems) to find those previously "undetectable" gold nuggets. Stacked up against any other gold detector on the market, the GM 4/B & GM 4/B HM (hip mount) will yield a measurable increase in depth and sensitivity, even in the worst ground conditions.

  • New!- ERS (Electronic Ramping Systems) Precision Ground Balance. It's a quantum leap in technology
  • New!- Pinpoint Touchpad...An additional tool in pinpointing the target if desired
  • New!- Hip Mount Version- 4/b HM...In addition to the 4/b configuration pictured above, the new Goldmaster is available as the 4/b HM (a body or hipmount only configuration)
  • Variable Operating Frequency... Goldmasters can work side by side without audio interference by simply adjusting the frequency
  • Phase Compensated Gain...Allows you to adjust gain or sensitivity without re-ground balancing
  • Selectable Signal Boost...The flip of a toggle increases the audio gain or "sensitivity" by 3X or 5X when desired to enhance the detection of deeper or tinier nuggets. Great for hunting bedrock!
  • Excellent Threshold Stability...Picks up even the tiniest of nuggets
  • Elliptical Search Coil...The elliptical design of the GM 4/b loop allows you to cover more ground with each sweep and presents an elongated window in the sensitive center of the loop for detecting the tiniest nuggets
  • Three Piece Rod Set At No Extra Cost... Breaks down into a compact package for easy transport. Locks together with rattle-free camlocks when assembled and ready to use
  • Silent search
  • Iron I.D. Meter & Audio...Needle "jumps" and the audio signal "crackles" on probable iron trash without any loss in detection depth when using the Iron I.D. feature... another Goldmaster exclusive!
  • Eight Cell 12 Volt Drop-In Battery Pack
