I sent my AT Pro in on the 16th of February and received it today just in time for the weekend. They even sent it UPS Red next day delivery. The gentleman I talked to at Garrett was very helpful and stayed with the repair all the way. They ended up sending me a new coil. I'm anxious to try it out tomorrow. My son found two 1950 quarters, 1903 Indian Head penny, 1916, 1918 buffalo nickels and several wheaties today with his Ace 350. Diggin it in Idaho.
