I started with the Coiltek 10x5" coil and EMI was so horrible I had to turn the sensitivity to 15. Even though it was at a low level of sensitivity, the coiltek still hit the silver ring at 7"!! After about half of my hunt was over, (I hunted for 5 hours) I went back to my car and installed the stock 11" coil on the 900. I arrived back at the area where I was hunting and the detector ran as quiet as a church mouse with sensitivity at 25.(max sensitivity: 28 ) Both are great coils! For pure raw depth, the award goes to the stock 11" coil. The slicing and dicing award in heavy trash / iron goes to the Coiltek 10x5". As far as depth comparison, the Coiltek is darn close to the stock 11". Thanks for looking!
