Detection
The types of hidden objects and materials that the detector responds to and the maximum depth at which it is able to detect these objects and materials.
The detection depth is a rather conditional parameter, and in fact there are often deviations from the claimed values both in one direction and in the other (depending on the material inside which hidden objects are searched for). As for the detection itself, modern detectors, usually, are able to find not only electrical wiring, but also other metal objects of various compositions ( ferrous
metal and
non-ferrous metal), as well as
wooden structures and
plastic pipes. However, the specific capabilities of the device in each case still do not hurt to clarify separately.
Auto power off
The auto-off time provided in the device.
Many modern wire detectors can automatically turn off after a certain period of inactivity. This saves battery life. The auto-off time is usually a few minutes — most often from 5 to 20.
Battery included
A
power supply is included with the device. In this case, a battery can mean both a disposable cell and a rechargeable battery; this point in each case should be clarified separately. Anyway, such a complete set eliminates the need to purchase a battery separately and makes it possible to use the device "out of the box" immediately after purchase.
Case (bag)
The presence of a case or cover in the delivery set of the device.
Soft cases provide mainly protection from dust and dirt, hard cases also protect against shocks and other contacts with foreign objects. What type of
case is included in the kit should be specified separately. However, anyway, the "native" case is better suited for the device than impromptu packaging.
