A few weeks ago teckpro asked me if the V3 could differentiate between silver and clad using the analyze display. My answer was "sort of". There is a subtle difference. However, with tone ID turned on, the difference is easy to hear. I recorded some audio samples that demonstrate this and uploaded then to Eriks Audio World here.
As a side note, I've listened to the audio samples from the Minelab and while the V3 differentiates between silver and clad just as well, the V3's audio is nowhere near as pleasing. The Minelab's audio is very flute like and rather pleasing as far as beeps and blips go. Looking at the V3's audio on a scope shows a square wave output. From the human ear's standpoint, this is the worst waveform they could output. It's loaded with odd harmonics that are tiring to the ear and not at all musical. Plus, the leading and trailing edges of a beep are basically a step that results in a pop as the speaker/headphones try to follow the waveform and of course overshoot.
Cheers,
John
