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.
Location depth measurements
The ability
to determine the depth of the object detected by the detector.
Devices with this function allow you to localize the position of the “find” as accurately as possible: not only to find out under what part of the surface the object is located, but also to determine how deep it is located. However the accuracy of determining the depth is usually far from one hundred percent; however, an error of a couple of centimeters in most cases is not critical.
Measurement accuracy
Measurement accuracy provided by the detector. It is indicated by the error that the device gives; accordingly, the lower the number in this paragraph, the more accurate this model, the smaller the error it gives during measurements. For models that have different accuracy with different materials, the smallest error value is indicated.
In the most advanced instruments, the measurement deviation is only 3 – 4 mm; in the least accurate — up to 13 – 14 mm. Note that high accuracy accordingly affects the price; so when choosing according to this indicator, you should not pursue
maximum accuracy, but soberly assess what error will be permissible during the planned work. Detailed recommendations on the required accuracy for various specific tasks can be found in special sources.
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.
