Global Positioning System (GPS) and Total Station:
GPS and Total Station, specifically configured for archaeological surveys are required not only for obtaining certain points or objects with absolute coordinates, but also to create a relative coordinate system on site. Having a relative coordinate system on site will provide an accurate direction for scanning. It also helps the project managers to better plan an excavation on site. We can establish the most accurate positioning by following relative coordinates. Finally, it also helps engineers to consolidate all image data and information gathered for analysis.
Metal Detector:
The metal detector is used very often to search for arrowheads, coins, knives and accessories in the archaeological field. A standard metal detector should be able to detect a regular coin, a quarter for instance, which was buried about 7 inches to 12 inches deep. A metal detector mainly focuses on searching for a shallow layer metal item.
