Thanks all and here is the settings below that I made note of for myself:
Thanks Bads Gold ,
Will give your settings a run . So far I have only used Field 1 or 2 hoping for a coin in trashy areas .
Hoping I can report in with some results in the future .
Cheers and appreciate your tips

VIP - Coil motion (swing speed) should be low and slow. This is because with the "accept/reject" (discrimination) being set to remove hot rocks, the hot rocks can mask a good signal but a slow swing speed gives the detector time to sample and allows for a solid positive "zip zip" on a good target. Also, the recover speed set higher (preferably 7 but 5 worked well too) allows for the detector to respond quicker when good target is masked by a hot rock or iron. Also VIP - only dig targets that have a repeating signal consistently when the coil is swung both directions (back and forth) over the target. VIP - gold nuggets that are faint will often at first not even register a number on the screen but will always have a consistent repeat signal back and forth. Unless masked by a hot rock this will be a smooth signal albeit feint. Once the nugget starts to register it will most often register a "1" or "2" on the screen but can range from "0" to "6".
Just some comments about the above settings and why. Firstly I noticed that with the 6" coil you get hot rocks coming in at two different settings -9 to -6 (mostly sitting in -9/-8) but also at (12/13). No matter what I tried, you just cant get rid of the hot rocks without losing so much sensitivity that you wont pick up anything above a 0.5g.
So you really have to "notch" them out and you have to go one or two numbers either side to smooth things out. When detecting you will hear this "masking" effect on the hot rocks and might worry that you wont hear a good signal, but if you go low and slow with the recovery speed 5 or above (I prefer 7) the good signals are unmistakable. Note that the detector starts to respond similar to the SDC/GPX in terms of slight changes to the threshold that are repeatable in both directions being positive targets even if at first you are not getting numbers.
Note, adjust the sensitivity as required but I would try stay as high as possible and wouldn't go below 18-20.
Threshold Level was using the speaker so with headphones can be 11/12.
With the 600, I cannot comment but in Multi in Park 2 i would try replicate the above as much as possible and see how you go.
Anyway, try these settings and remember when you do that you still have to walk over gold.
Am keen to know if these help any of you - that would be great.
Picture of the small bits all together - smallest wouldn't even register unless I had another piece on the scale.
