Makro Gold Racer - iSat & Sensitivity optimisation

[VoGusProspecting]

Hey mate, several questions if I may.
I have the gold Racer and have the gr26 and gr19 coils.
Which coil is better at finding small gold, talking around the 0.1g possibly smaller at the base of mullok heaps.

As I understand this video the ISAT setting will decrease the time the detector takes to recover from ground noise at the cost of depth?
So you could probably increase sensitivity if you're running a higher ISAT so long as the threshold stays level?
When adjusting ISAT and sensitivity do you play with the threshold and if so how/why?

The area I'm in has a few places where it's possible to find gold from 0.03-1 gram commonly, so any suggestions on making the machine pick out those small targets?

Hi Nerad, what goes deeper the Gold Racer or Gold + ? I would be interested on a Gold+ field test.
