I decided to clean the nickels that I have been finding with the Equinox. I might have too much time on my hands digging nickels but the Equinox makes it fun. I run in Park 1 and usually make use of the notching feature by setting the detector up to only hear 12 and 13 and everything higher than 18. Total nickels found - 72... One Buffalo - two War nickels - 2 others from the 1940's - 2 from the 1950's - 8 from the 1960's -8 from the 1970's - 16 from the 80's - 26 from the 90's - and only 6 greater than 2000. I did have three other Jefferson's that were in bad shape and I could not read the date. I have never found a nickel over about 4 1/2" deep with the Equinox. It is nice to read posts with other people finding them much deeper.
