MINELAB Gold Monster 1000 Detector Bundle w/PRO Gold Gold Panning Kit

  • ...lly automatic operation and comes with a choice of coils, battery options and shaft configurations. If you're looking for super sensitive gold performance at a great price, then this is the detector you've been waiting for!.
  • An 18 kHz detector will normally have a depth advantage on nuggets ≥ 1.0g over a basic mid-frequency detector, and a 71 kHz detector will have a depth advantage on nuggets ≤ 0.1g. The advanced GOLD MONSTER 1000 uses an intermediate 45 kHz frequency AND a high speed 24-bit signal processor. This primary combination greatly boosts sensitivity to gold beyond that of other single frequency VLF detectors over a wide range of nugget sizes, without introducing excess noise and false signals..
  • Features: Fully automatic operation, Extra sensitive 45 kHz VLF performance, Highly adaptable, 2 search coils included, Easy quick start, Automatic noise cancel, Digital electronics, Auto ground balance, Faster processor, Automatic sensitivity.
  • Specification: Key Technology: Ultra-wide dynamic range 45kHz VLF, Detect Modes: Gold (Iron reject), Deep All-Metal, Discrimination: Gold Chance Indicator (high/low), Ground Balance: Automatic (Easy-Trak), Noise Cancel: Automatic (On start-up), Sensitivity Adjust: Manual (1–10), Auto (11), Auto+ (12), Vol....
