I haven't 470pf...
Problem is that i haven't a very good field (test area).
When i find an object, i dig quickly and take it before other see me.

No... i have find a little piece of gold (once), copper objects and rust irons.
Problem with iconos is that it is not stable....
Today maybe to locate an object from 10m and tomorrow nothing
DCH85 has better way for discrmination....

Hello again...
Today i made a modification to my pistol detector and i increased the sensitivity.
All was ok but when i turned the beep generator on i saw same problems as with Andy's Flind detector. The buzer stimulates the coil and creates a loop with beeps. When i lower the sensitivity it stops to beep. So this time i decided to create a wireless beeper. I had a transmiter and a receiver from Arduino experieces (many years ago) so i begun the test...
1st test all fine
2nd test.... the transmiter stimulates the coil and keep the receiver in saturation...
Tomorrow i will try to reduce the power fo transmiter......

The problems with wireless beeper are more than what i had fantasy....
I"ll give it 2...3 opportunies still. After it i have a 5kgr hammer

Beeper is near to finish .
