Gold Metal Detectors 2011
Gold metal detectors are used to find small and large gold nuggets. Small and slightly small gold nuggets can be detected at medium depths. Large gold nuggets are the most difficult to search and locate. Gold metal detectors have ground balance modes for alkali soils and black sands for smooth operation. The maximum sensitivity of a gold detector helps to locate small gold bits at greater depths. It can operate with ideal frequencies for locating gold nuggets. The search coil used in gold metal detectors is water proof. Additional features of gold metal detectors are meter display, manual group balancing adjustment and discrimination adjustment. These supplementary features vary with the technology used in each type.
Gold metal detectors are generally based on digital technology. They have automatic and manual modes. The auto-trac feature cancels the ground minerals in seconds and then tracks to the changing conditions. The features include iron audio signal, LCD display and bar graph. A microprocessor monitors and stores the ground mineralization value. The graph displays the percentage of probability of iron and the amount of magnetic minerals in the ground.
Advanced gold detectors have maximum depth and super sensitive features. They have digital ground balance with switchable speed recovery. The ultra high frequency gold metal detector is designed to find gold nuggets at greater depths. They use elliptical search coils. The features include high sensitivity, high operating frequency, iron discrimination and audio boost facility. The mineralization settings may be low, normal or high. They can operate in mineralized soil with a three position mineralization switch. Some of the advanced gold metal detectors have three modes for speed tracking. Slow, medium and fast tracking modes help to improve the detecting. Advanced gold detectors can also resist dust and moisture.
Some of the advanced gold metal detectors have manual tune control feature. The manual tuner helps to select various frequency bands. Multiple frequencies help to attain more depth, sensitivity and more accurate targets. The tune control minimizes electrical interference from power lines, radar and radio transmitters. Gold metal detectors are lightweight, water proof, cancel noise and have ground balance and on board computer chip.
