Some detectors offer automatic ground balancing, while others allow you to manually adjust the settings based on the soil conditions.
4.4 Size and Weight
The size and weight of a metal detector can significantly affect your comfort and convenience during long detecting sessions. Consider the length of the detector’s shaft and its weight to ensure it is suitable for your height and physical abilities. Additionally, look for a detector that is easy to assemble, disassemble, and transport, especially if you plan to take it on outdoor adventures.
4.5 Target ID
Advanced metal detectors often feature a target identification function, which provides information about the type of metal detected. This feature can help you differentiate between valuable targets and common items like bottle caps or nails. Target ID is typically displayed via numerical values or on a graphical interface, helping you make informed decisions about whether to dig or not.
Now that we have explored the key features to consider, let’s move on to the next section and discuss the best metal detectors for different applications.
