Dual Voltage Technology (DVT)
Dual Voltage Technology (DVT) is an innovative technology developed by Minelab, which is incorporated into some of their metal detectors, especially those designed for gold prospecting. DVT is designed to increase the sensitivity and depth of detection by using two different voltage modes to process signals reflected from the detected objects. This technology is key to improving detector performance in a variety of soil conditions, particularly those with high mineralization.
Key aspects of Dual Voltage Technology (DVT):
-
Dual voltage pulses:
- DVT works by transmitting pulses at two different voltage levels during a single search cycle. Each voltage pulse has the ability to detect different types of metals and provides different information about the location and depth of objects.
-
Improved detection of different metals:
- The higher voltage focuses on detecting larger and deeper targets, while the lower voltage is more sensitive to small pieces of metal closer to the surface. This allows users to more effectively locate a wide range of metals.
-
Performance in mineral rich soils:
- DVT is particularly effective in highly mineralized soils where standard detectors can have problems with discrimination and depth range. The dual voltage mode helps overcome the effects of soil mineralization and increases the probability of detecting targets.
-
Adaptability:
- DVT technology provides searchers with the ability to adapt the detector to specific search conditions by allowing users to choose which voltage mode is most appropriate for a given environment and target.
-
Noise and interference reduction:
- The use of two different voltage levels also helps minimize noise and interference caused by ambient electronic equipment or geological factors, resulting in cleaner and clearer detection signals.
Dual Voltage Technology (DVT) brings significant benefits in metal detection, especially when searching for gold and other valuable metals in challenging terrain. This technology increases the efficiency and accuracy of metal detectors, allowing prospectors to achieve better results in their prospecting activities.
