Why is there a setting for power as well as one for sensitivity?

[FORUM XP]

This enables experienced users to match the power of the electromagnetic field to the specific characteristics of their environment.
In particular, they can reduce the power on difficult ground, where it might otherwise interfere with interpretation of the signals.
Power has a subtle effect on the device’s pure performance, especially when compared with sensitivity. However, it also has a non-negligible impact on the device’s power consumption, and can influence stability when used on difficult ground.
DEUS enables you to adjust the power according to 3 levels (1 to 3).
On iron-infested, mineralised ground, there is no need to use a high power setting, level 1 will be sufficient as you cannot detect in this kind of ground as deeply as in neutral ground.
It is therefore better to limit the saturation caused by iron and the ground by lowering the power setting. In this way you will improve analysis and will ultimately find as many, if not more, targets since you will be better able to perceive them.
In most of the programmes, the power is set to level 2 by default, which offers a very dependable performance level that is largely sufficient in most cases.
NB: the power cannot be adjusted when the frequency is set to 4 kHz, it is fixed at the maximum level. You do not have access to the EXPERT menu when you are on this frequency. It is mainly reserved for a forthcoming XP accessory, which will be particularly suited to searching for large, deep masses.
