There is so much more to learn about the 5k, eg..
From memory on a test I did, (in particular settings) a 0.3 gram bit at 10 inches I can make it sound like a 1 grammer at 3 inches just by switching from fine gold to sensitive extra with the 17x13, if I drew a responce/depth curve the responce dips away massively beyond 10 inches.
Searching in sensitive extra either in fixed or tracking is an absolute nightmare so can only be used to amp up the responce of a deep wisper of a small nugget within the 10inch range..
To add..
Searching in super slow mo, the target can actually be up to a meter away from the original responce field, so my scrapes are sometimes massive. On top of that an aluminium can 2 metres away effects it, I have to sweep far and wide to determine if I'm hearing a deep wisper or the edge of a distant piece of junk..
Another reason why my custom fibre shaft is at full length of the coil cord to get it as far away from the metal of my external speakers that combined with the target in my spoon seems to create a recirculation of responce to the system..
And now that I've replaced a faulty patch lead its even worse..
