It's been a while since I could hunt because of the heat and no rain.My ground is just about rock hard and it's moderate mineral content.I decided to bury another coin or 2 to test the Classic 3SL in these kind of conditions.I am using the 5.5 ferret coil that I bought from Monte about 13 or 15 years ago.I'm also using the Classic 3SL with Mr.Bill Mods that I also bought from Monte.I have a nickle buried flat at almost 8 inches and with the detector at max disc and sensitivity just past preset I can still get a good signal... not loud but enough you would not pass it up.I put the sensitivity to max and left the disc on max and I could raise the coil 3 or 4 more inches higher and got a good sounding signal with no problem. Then I put the detector in the black sand mode with the min disc and got a good strong signal and then increased the disc to max and it was almost as good as my air test.I use ruler to measure distances.I really love the Modulated audio as to help tell me the depth.A lot of newer detectors don't have the Modulated audio and all signals sound the same no matter what the depth.Of course if you have a depth meter that will get you in the ball park.This detector already had the Mr Bill Mods when I bought it from Monte and it also has the SAT Mod which is another great feature! Also the battery life is 60-80 hrs depending on quality of batteries and headphone use.Monte...IF you read this I just want to let you know that the Classic 3SL I bought from you is still working like a champ and It would be the last detector to go if I had a choice which I'm thankful I don't! The Classic 3 SL is a Great detector even without the Mods but if you can afford to get the Mods it is well worth the bucks and really increases the performance.The features on MY Classic 3-SL are...Mr Bill Mods which includes the external Threshold and Ground Balance Adjust..and external SAT Adust which is an external 2 way switch to toggle between Factory and Moded settings-Plus an increase in sensitivity that works similar to some of the Tesoro models like a Max sensitivity boost past the 3:00 oclock position to max.Anyway it will keep up with a lot of newer machines an surpass a lot of them in iron and masking because it has a very fast recovery speed.With the smaller coils it's a killer in and around nails and other trash..iron or not. I haven't done Monte's NailBoard test yet but I'll post when I do.I have other detectors but this is still my favorite!
