I had the perfect, junky spot to check out my new 6 inch dd coil. I am always amazed at what we miss with the bigger coils. I hunted a well used park-picnic area that I have been to many times and I found 42 coins, with 4 being wheats and one sterling silver womens ring. The wheats and ring were 5 to 6 inches deep and all but one had a piece of junk real close. I have noticed one thing when using the patterns. The signals are not real crisp like they are in all metal. Even the coin signals were scratchy. Even in these trash infested spots, I use all metal most of the time. The noise keeps me on my toes. I have tried small coils with the many detectors I have owned and up until now, I had always thought a Tejon or Vaquero with a 5.75 inch coil was the best. That was until recently. The x 70 with this dd is a true precision accessory. I now have a complete setup that I have total confidence when I go hunting. R.L.
