If you are talking about the 6 X 10 DD eclipse coil it is one of my favorite coils to use. It stayed on the MXT I had and now I have one for the V3. I do not pay attention to what the ground probe suggest, but adjust everything where the V3 is running smoothly. It has great depth and target seperation and to me is a great all around coil to use ie. tot lots, parks, yards and woods. Saturday I hit a pockect spill at 8" with the V3 and 6 X 10 DD coil. I too have the 5.3 and it surprised me at the depth and target seperation it has great coil in trashy areas. Hope this is helpful to you.
