Comparison Upinttor MD-4030 vs Treker GC-1066

The size of the standard coil (frame) of the metal detector. Theoretically, the larger it is, the deeper the device is able to “see” and the more space it captures in one pass, but the worse it is suitable for searching for small objects and the lower the accuracy with which it localizes them. At the same time, these characteristics depend on so many other factors that in fact, the size of the coil itself affects them very little.

Note that for coils (frames) of an elliptical shape, only one size can be indicated — along the length.

The deepest depth at which a metal detector is capable of detecting small coins and other objects of similar size. Many users buy a device with the intention of “hunting” for metal trifles, so manufacturers often indicate this parameter separately in the specifications. Due to the small size of the coins, their detection depth is usually much less than the total maximum detection depth (see above).

The total weight of the metal detector in the working position is with the installed coil and batteries (if both are removable, see above). This parameter is quite important, taking into account the fact that during operation the device has to be kept on the weight: long-term use can be very tiring even with a relatively small weight and the presence of an armrest (see above). Therefore, light weight is a noticeable advantage for any metal detector. At the same time, other things being equal, lighter models tend to cost more, so you can use another option — a shoulder strap that reduces the load on the hand. And for underwater metal detectors (see "Type"), this parameter is not particularly relevant, because. objects underwater lose a significant amount of weight.
