Obolo, your pics are blur ((( but resolution is nice!
can you turn your camera in Macro mode, at first (flower sign)? At second, can you zoom image on maximum? (i mean the optical zoom, NOT DIGITAL).
thank you!

FatBob made nice job, your detector has full similarity. i did give there schematics.Comment

I messed around with a Bandito for a while and the two things that definitely made a difference were
adding a diode to the 4024 diodes (this added 1/2" depth) and changing the filter cap on the last LM358
(better sens). See this schematic;

I found test on the Bandido to be insistent with air tests in the house.
The auto tune in no motion mode it badly affected by electrical interference in the house and throttles back the threshold with the result of poor depth.
In discrimination you can run the sensitivity at 100% and get an extra inch or so by waving a coin at the same speed as chirps and you will get a solid beep every time but you cant't run the detect this hot in the field.
In the ground I get the same depth as air tests in the house even though I am running it less hot.Comment
