I put my TS800 coil on the musky and tested it 1st in disq and it did fine on the 6" dime and a good wisper on the 7" but was silent on the 8' so i put it in all metal and groundbalanced just a bit positive and set the treshold just to whear it will start to click and i got good signals on all even a ten inch buried dime that my soverign cant hit in all metal amazing Sov is so soft i dont know if i would dig the 10" signal but the musky is very clear i have never tried the 800 on the SOV
