I only had an hour or so to hunt so I tried some settings that would let me cruise the fringe areas of an older site with the thought of covering a lot of ground looking for the easier targets.
This is a cornfield with bent/broken cutoff stalks and uneven furrowed ground. My first thought was how the heck to GB as I had my doubts about using tracking with a faster sweep over the uneven terrain. Right or wrong I decided to GB to the damp soil in the lower part of the furrows which resulted in a setting 4-5 numbers higher than the drier areas.
Wanting to hear <i>just enough</i> iron to help distinguish false signals from good targets quickly and without having to revert to all metal, I notched in -2 and -6. -8 is mostly hot rocks and +48 readings at warp speed are iron falses with a sens of 21 so I chose not to hear those. I also notched out +2 and +4 but the left the rest of the segments open to alert me to targets off the edge of the coil that do not initially read where they belong. Threshold was set at the fringe of audibility (3) but I probably would have been just at well off using 0 because of the fast sweep negating any benefit of listening for nulls.
With these settings iron was not a problem, what few iron falses I got were easily identifiable on resweeping with the segments I had left open. Only dug a couple foolers which were larger rusty nails down deep.
I was using the low freq coil and found that the "scan width" is very wide. Non-ferrous coin size targets were giving audio hits off the edge of the coil at depths of 4" or more. This is a good thing, perfect for cruising since I was using little to no overlap.
Overall I was very happy with the detectors performance in a mixed area of low to heavy iron using a <i>too fast</i> sweep. Sure I was probably missing the tougher co-located targets in the iron areas but I accept that since my goal was to cover a large area anyway.
Only got one coin, but it was a keeper, an 1896 Barber quarter.

Can't wait to get the 70 and Edge in there for some more goodies.
