I just got a 10 1/2" coil in the mail today for my CZ70 Pro from Relic Hunter Supply. I have been curious how much it might improve the depth of my CZ70. It goes pretty deep with the stock 8". I did some air testing with it and it did give me 2" more on a silver dime and a clad quarter. With the 10 1/2" coil I got 12 inches on the dime and 14 inches on the quarter. It will be interesting to see how it does with real targets in the ground.
Also checked the depth on a 58 caliber minnie ball and it was around 11 1/2" on the 10 1/2" coil air test. Taking it out to a Civil War campsite that we have been hunting of late. Have been pounding it pretty well and am anxious to see if the new coil might find some targets that may have been just out of reach with the 8" coil.
Anyone else out there that has used the large coil on their CZ?
