Tesoro Lobo news

Unfortunately, our boards are not exactly the same. I had to modify mine, circled in red. I see that you have an IC 4558 at the input, mine is a TL062, I had no success with the 4558

The Tesoro Lobo generator can operate at frequencies from 10,000 to 100,000 Hz, but the sensor needs to be designed for this frequency and the frequency response adjusted. Yesterday I watched a video on YouTube of the DEUS 2 generator (white boat) in action; the frequencies for gold are 40,000 and 76,000 Hz. One problem remains with the Lobo: you need to achieve a normal amplitude in the TX. These frequencies are purely for gold. For coins, the maximum is 30,000 Hz. With my homemade Lobo M with a 32x24 sensor at 17,400 Hz, I achieved a range of 50 cm in the air with a large copper 5-kopek coin. This is, of course, a gimmick; it's a shame there's no way to test it in real soil. Perhaps the soil triggered the detection. The factory circuit can be improved upon. I also realized that it is better not to use a frequency of 100,000, even with an amplitude of 10 volts, near the head, as it has a strong effect on a person.

Hey Travesil!

I'd like to build the Lobo M. Do you have any information about it? Could you share the PCB layout and the coil construction details?
