I recently got a ETP with the 8" round coil. Have only been able to get out with it once, but was impressed with its performance. Tried hunting a very junky yard that I had gone over with one of my top end detectors, and a friend has also hunted it 4-5 times. Only hunted about 30 minutes because of the weather. Found 22 pennies, 6 dimes and 1 quarter. All clad. Couldn't believe there was that many coins still at this location. ETP definitely has a fast retune speed. I hunted in zero disc. to help eliminate target masking. Cant wait to get out again . Mark
