Impulse III Metal Detector short Review

This project is sponsored by PCBWAY Recently, quality metal detector modules have appeared on the market for a very low price. This time I will present you one such module and I will try to briefly capture its features. To put the metal detector into operation, it is necessary to solder only six wires, two from the power supply, two from the speaker, and two from the coil. The coil consists of 25 turns of enameled copper wire with a diameter of 0.4 to . The diameter of the coil is 20 detector worked immediately after switching on, but only required some adjustment. As in the previous review for the Clone Pi-W Metal Detector, I am really pleasantly surprised by the features such as sensitivity and stability in operation, considering that it is a very inexpensive module, and to make a complete mid-range metal detector we need almost no knowledge from the field of electronics. This time I would like to emphasize that the results were a little better, but in real conditions, in moderately wet soil, many false alarms occur, so to avoid that, filters are used that also slightly reduce the sensitivity. Thus, the final result when comparing these two metal detectors is almost identical.
