Depth is determined from width of a coil not length so the coils will be the same in depth . However that hotspot center of coil will be larger on the bigger coil making it appear to hit harder under the coil (ANOTHER WORDS A LONGER HOT SPOT) .
So the bigger coil will cover more ground at depth per sweep than the 11 but no deeper .This is what I always thought and till someone proves otherwise I will stick to this . sube
