Here’s some things I’ve noticed..have a 6 and 8 inch mercury dimes,,and a 10 inch Washington,,all honest depths from coin to soil buried over 8 years ago easily...multi kruzer no matter what mode or disc will not hit the 6 inch merc with gain at 89 or lower..Put it at 90 and it hits the 6 and 8 inch mercs ..I as in all frequencies for that test,all the same results running in 2,3 and 4 tone modes....In 5 kHz with gain at 95 in 4 tone and 3 tone it crushes the 10 inch Washington.Havent tried 2 tone on that one.
Got some more testing to do,but I would suggest deep coin hunters in western Pennsylvania at least,,not go below 90 gain,At 90 gain it will hit hard in all frequencies,deep coins..5 kHz will absolutely crush deep coins,not many machines will hit that 10 inch Washington including the Etrac I recently just sold.And I have a lot of time on the Etrac,no setting would touch it..As a matter of fact the only machine I recall ever hitting the 10 inch Washington was a xterra 705 with a tornado coil,that was a deep combo.
I had a Impact,but didn’t care for-all the modes,never used them and really sold it for that reason.
I’ve been looking at the 15x14 inch coil,not sure though,that’s a lot of do re me..I have it put away,just trying to justify the expense...I have no other coils but the stock,but I must say with a little fiddling it’s very impressive..I’m just so surprised that 89 gain would not even peep on the 6 inch merc,,one more point of gain to 90 and it blew past the 6 inch merc and slammed the 8 inch..
