The users usually are curious about the depth! The depth capabilities of detectors are affected by numerous factors. The most important among these is the mineral composition of the land.
In this vein, the stature of the target, the time it remained buried, type (gold, iron, steel, copper, silver etc.) weather conditions, and user all affect the depth capabilities of the detector.
The operating principles of detectors, their frequencies and coil characteristics, as well as software are also important factors in this regard.
For instance in case the motherboard and the analog card is not stable and is prone to noise, this would pose a critical problem.
This is usually the case with incorrectly designed or incompatible cards. Incorrect calculations or incorrect adaptation at the software stage is also a problem observed. All such factors affect the depth capabilities and the ease of operation directly and adversely.
