The rule of thumb is that, to gain another inch of depth the gain must be doubled. This means that increasing the gain form 14 to 15 will not improve depth much at all whereas increasing the gain from 2 to 4 should gain another inch. So 4 to 8 another inch and 8 to 16, oops no 16, another inch. So don't get crazy on setting the RX at the upper levels because it provides diminishing rewards. In some cases the added noise will actually negate the increase.
So in my opinion, higher RX and more noise and signal loss would be about the same as lower RX with less signal loss . The bottom line is, with any coil, run the gain as high as you can for stable operation, just as you'd do with any detector. Rob
