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....

YWBL-WH Logarithmic Power Detector Meter AD8317 1M-10GHz 60dB RF Power Meter Logarithmic Detector Controller for Amplifier 50 Ohms

  • AD8317 CHIP---The logarithmic power detector is designed by using AD8317 chip, and is used for RF signal power detection.
  • -55dBm to 0dBm---The logarithmic power detector can detect power in -55dBm to 0dBm of an RF signal, so that the RF signal is converted to DC voltage output.
  • APPLICATION AREAS---The logarithmic power detector could be used for RF transmitter PA set point control and level monitoring.
  • Power monitoring in a radio line transmitter.
  • RSSI measurements in base stations, WLAN, WiMAX, and radar.
  • 55dB---The greater the amplitude or power of the RF signal, the higher the output voltage, and the output voltage is directly proportional to the logarithm of the input signal amplitude, thus expanding the dynamic range of the detected signal, which ranges reach 55dB.
  • WIDE APPLICATION---The logarithmic power detector could be widely used radio frequency signal detection, signal power measurement, environmental field strength detection, or as a part of automatic gain control and automatic level control.
