Do Minelab PI detectors make a different sound depending on whether the target is ferrous or non-ferrous? I'm pretty sure i can hear a difference(non ferrous to me sounds a bit more sweet and "squelchy")but i'm not sure if its just my imagination. I've done a search online but i couldn't find any definite answers.

hmmmm, I dont dig 'echoes' or 'double blips'?
They will always be bucket scrapings or shoe tacks!

I hear a difference
I can go out and come home with just lead and gold
But this changes with targets at depth
ATM I pick my targets as I'm not as fit and resilient
As I normaly am
And go with me gut a fair bit
I stopped digging double beepers a while ago
And just dug the odd one here and there
But one day I got a double beeper inverted
And thought it would be a deep nail
But dug anyway
Glad I did cause out popped this unusual
6 grammer

I once sent a mate out to spot where I got some gold, not much however. He came back very happy with 3 nuggets weight about 8 gm. He asked me to come out and check the spot. I went over it quickly and got five double beep signals and said maybe small tacks but dig them up. It turned out to be all nuggets about the size of a finger nail standing vertical in a reef. He ended up with three and a half ounces of gold form the reef.
Most nuggets are usually said to be gold from a combination of tone, sound size, and mellow depth sound but it is not always correct. Some of my large surface junk signals turn out to be multi-ounce nuggets

a 7oz nuggy at two inches sounds excactly like a horse shoe at two inches....but i don't mind if other people walk away from crappy signals.. Wink
cheers

Your absalutaly right fence jumper
Gold doesn't always sound like gold
And is also masked by rubbish
And if you don't dig everything
You will walk away
From gold
The old Moto
Low and slow and dig everything
Is the way to get all the gold with your name on it
And do the area and surrounds
Thoroughly

Some of my larger bits of gold were wobbly,iffy signals at depth,just like that given off from rusted pieces of iron.At depth in the ground,it would be almost impossible to determine the difference in signal,between metal composition with a PI.Also orientation of target to angle of coil detection,can change the sound,just like that of the double bleep you might get on a length of rusty nail,when nail is sitting at a horizontal angle to the coil swing,but a single beep when nail is sitting vertically to the coil swing..Larger gold targets closer to the surface can sound like an aluminium coke can or horse shoe to a PI. Only a VLF with an inbuilt notch/tone discrimination system,will get you more accuracy as to what the difference in signal/tone might be and again signal/tone accuracy will decrease as the same target is found deeper.To many variables involved in determining the consistency of signal type on a PI fellas. Like fencejumper and Ibg dreamer state,if your not digging up all positive signals,meaning signals that beep both ways when swung over with your coil,the chances are one of those targets might be gold.

No more that 2 days ago I dug or should I say scraped a target that I first though was going to be a nail on the surface, as that is how it came in screeming at me. Scraped the surface checked it with my magnet that is attached to the end of my pick handle, and no nail or rubbish. So then thinking a bullet scratch Using my scoop check my scrapings and out came a 2.62gm nugget that was almost sitting on the surface. SO CHECK ALL TARGETS Very Happy Gold has no particular sound
