I have the Storm on the AT Gold....I just got it about a week ago. So far....I like it a lot! It is whole lot bigger than the 5X8 DD stock coil! Lots of coverage and more power from the larger coil which has those questionable hits on the smaller coil sound loud and clear on the storm. I have found so far that it def doesn't have the iron discrimination that the 5x8 has but that is something I expected before even buying. Just today, I was using the storm in a large field and found an area that was littered with iron. It sounded like a firework show! I ended up finishing the area with the storm and then coming back to that littered iron area and switching out to the 5x8 to get that separation I was wanting. When I first got the storm, I took it out in the back pasture to a small area where I have hunted over and over again. I found several more late 1800s and early 1900s shotgun headstamps and a 1902 Indian Head penny. The Storm is something I like to trade off for a massive amount of coverage and the increased depth for those on the edge hits that i was getting and those I was missing. Right now I will use it accordingly...depending on the area I am detecting......Good Luck & Happy Hunting!....Kyle
