First off, the description about these coils going deep is accurate. They will go DEEP. I pulled a piece of metal the size a pencil eraser out at 8" and it was giving a solid repeatable signal. It was trash but showed me how deep it can go. I also pulled some sort of copper valve that was about 2"x 2" at nearly 11". I have a dime buried in my test bed at 8" and it gives as strong a signal as my stock coil does with one buried at about 3". Separation is pretty good for its size. you have to listen but you can pick out the high tones through the trash. Usually I will turn 90 degrees and swing over it again and the it will pick out the good target. I would not recommend it for very trashy areas though because it will drive you crazy. I mostly use it in areas where where I need to cover a large area or the grass is not mowed and I cant get my other coil right to the ground. Pinpointing takes some getting used to but with some practice its not difficult and is pretty accurate. Being as large as it is you can cover ground quickly but, you will need to swing it fairly slow. Now to the only downside, and the only reason I gave it 4 stars instead of 5, the weight. I'm 40 and in pretty good shape. I can only swing it for about an hour before I need a break. It gets heavy but I've noticed that if I slow my swing down it helps out quite a bit with fatigue. Overall, this is very good coil and worth the money but, like any tool it has its uses and is not meant for all situations such as highly trashy areas and you definitely need room to swing it. I would recommend it and would buy it again. Lastly, Colonial metal detectors was great and shipping was fast! I ordered it on a Friday afternoon and it was on my doorstep Monday afternoon.
