The soil is what they call gumbo and can get hard as a brick when dry. The ground will actually crack and a lot of the coins fall down in the cracks and when it rains the coins are now on edge. We get a lot of targets that are dug on edge. that is another thing a machine has to be for me to keep it. It is a must to be able to find coins on edge at at least 8"s. Don't know about the coin strike. Had one put 200 hours on it and when it would not hit a quarter deeper then 8"s it got gone in a hurry. Cortes,1500,Conquistador,Classic Id are all 8 to 9" machines down here and why I don't own them. Got a Exp ll with the Joey coil will get 8 to 9"s and that is all. Same with the 7.5" M/L coil. Don't hunt with the big coil but it is 10 to 12 in wide open places but I don't hunt in those kind of places. I have been hunting for 20 years and NO they don't fall down in the hole. I hunt the old deep coins down here. I can go dig clad all day long if I want to. I am not interested in digging clad unless it is quarters and dimes and I do go quartering once in a while. In most places I can run high sensitivity and get away with it. Besides I have hunted with Fishers for 20 years and I know what is a good target from a false target and I dig very little iron with my fishers. Dig more iron with the M/L's then I do with my fishers. BTW the little ID Edge is great in the iron. Just put the little 5.75" coil on and dug a 1903 barber dime yesterday at a measured 7"s. When I am testing new machines and new coils I always take a tape measure with me so I will know for sure and I am careful about digging as I need to know the machine will at least go 7 to 10+"s as that is where the old coin strata is here. Like I said if you don't have a good machine that will Id and go 7 to 10"s you might as well go home and take up something else. Not very many old coins have I found at under 8"s down here and if they are down less then 8"s then it is in the trash or the Iron. You must have a coil and a machine that will separate targets above and beyond all the other machines. . I spend a lot of time metal detecting and not much time Posting. There is not much competition here as most of the old guys have died off but they sure put a hurting on the places I hunt. Not much good stuff left and what is left is deep as hell. So come on down here and I will treat you to some of the finest food you ever ate. We Cajuns know how to eat. Bring your Fishers, Shadow X5, Mxt,( The only Whites worth anything) or Explorer,or Sov. and you will really see what digging a deep target is all about. I will take you to some places that is so filled with Iron and trash that it makes guys give up on metal detecting, but that is where the good stuff is. Oh bring small coils and don't plan on using anything over 8". DD coils do work good down here though. Sorry for the long Post but you seem to have Challenged me and I just wanted to put you straight on a few things. Sorry if you don't believe me. The old guys around know me and know I don't B.S.. I tell you just like it is. I own the best machines on the market. This is my hobby and I put a lot of time in on it. Why in the hell would I even own a machine that does not preform at the depth I need them to preform at. The only machines that will preform down here are Fishers, MXT, Shadow X5, Sov., Explorer, and the Golden MM ( but only if you run the Golden at Max and small coil). Well later and HH Jerry aka Tinfoil
