Sensitivity to Large Targets: Explained

When it comes to metal detecting, sensitivity is one of the most important aspects. Sensitivity refers to the ability of a detector to detect small or deeply buried objects. However, when searching for large targets such as coins, jewelry or relics, high sensitivity can sometimes lead to false signals and wasted time digging up unwanted targets.

This is where sensitivity adjustment comes in. Most metal detectors allow users to adjust their sensitivity levels according to their needs and environment conditions. In general terms, increasing your detector’s sensitivity will help detect smaller targets while decreasing it will reduce interference from mineralized soil or other elements.

However, when looking for larger targets like silver dollars or belt buckles, a lower sensitivity setting may be more beneficial as they emit stronger signals that are easier for the detector to pick up at greater depths.

Another factor that affects detection of large items is coil size. Smaller coils are better suited for locating smaller items while larger coils offer more depth and coverage but may struggle with identifying specific targets in areas with high trash density.

It’s also worth noting that different types of metal have different magnetic properties which can affect how easily they are detected by a metal detector. For example, gold tends to be more difficult to detect than silver due its low conductivity and susceptibility to interference from surrounding minerals.

In conclusion, understanding how your metal detector works and being able to adjust its settings according the target you’re searching for can greatly increase your chances of success in finding valuable treasures. While high sensitivity may be helpful in some situations, don’t overlook the benefits of lowering it when searching for those bigger finds!
