I just got the small coil for the CS and I was hoping that it would be a a good trash coil. I have put most all of the small coils on every top end detector made and I always come away disappointed. It seems that they all do a good job of separating trash from coins, but some lack depth, some seem to change tones, and some seem to change VDI numbers. Up until the 5.5 CS coil, the best I have used was the 5.75 Tesoro coil on a Tejon or Vaquero. I bought the CS because I think it is the best trashy site detector made and I was hoping the small coil would get decent depth and the tones and numbers would remain like the 8 inch coil. I used this coil for about 10 hours this weekend and I took it to two spots that still hold some older coins and both of these places are loaded with all kinds of junk. I had no trouble with the tones and numbers locking onto coins and the coil was super at getting coins that were surrounded by trash. I just didn't find any coins deeper than 4 or 5 inches and I figured that these spots would have coins in the 6 to 8 inch range. I sort of figured that the coil might have a 4 or 5 inch range and I was happy with that and it's quick, accurate response. I was just about ready to call it quits this morning when I got a faint repeatable 24 to 25 signal that pinpointed at 20. Finally I had a signal that should be a deeper coin and it turned out to be a 1919 wheat at a measured 8 inches. That answered the depth issue. I ended up with one more wheat from about 7 inches. I found 50 coins this morning along with two silver rings. I was able to run my sens at 10 with the threshold at minus 5. I notched out foil and tabs and the detector and coil worked better than any small coil setup that I have ever used. I have had small coils that would change the pulltab range to read as coins and I was hoping this coil would not do this. It did not and I guess you can see my satisfaction. I hope they come out with a coil cover soon. HH R.L.
