Recently picked up an old blue box Eagle II and would like to buy some additional coils. Back when this detector was state-of-art the coil selection was limited. I'm hoping that some of the newer coils being made will work with this old workhorse. So, my question is, which newer coils are the same frequency and will work with the Eagle II? I do have the 950 coil, but would like to find a smaller 6" or perhaps an elliptical coil.
