Recently read Digger (Randy) article on Coin Shooting with the X-Terra 70. What really caught my attention was the section on Sensitivity. He states that he likes to think of the Sensitivity, Threshold and Ground Balance working hand in hand. If you have the sensitivity set too high, you will not likely obtain the optimum GB setting. He went on to recommend setting the sensitivity at a single digit level, until after he set the GB. After achieving the proper GB, he turns the sensitivity up as high as he can, with out causing false signals.
I followed these directions and set my X-70. Only I was hunting civil war bullets and not coins. I then set my sensitivity to 25. I was using the 7.5 standard coil. The area I was hunting has been heavily hunted. I recovered to two two-ringers and four three ringers. All the bullets were at the 6" to 8" depth and a very Strong 32 on the meter.
