I will ask this question which must have been ask before. I use a White's 5900 Di Pro Plus with the Six inch Blue Max coil. This is a stock standard detector bought off the Bay and have used it the last two years. It is good to about five to six inches on coins. Even with the 12 inch Hot Head Coil seems I get a couple of inches more out of it. Even with a 50% over lap of coil sweep I feel like I am missing some of the deeper coins. Any suggestions out side of ground balance and upping the sensitivity. I run in all metal mode most of the time. I am aware that the meter is one of the best for VID. Granted most of my silver coins are found three to five inches yet I hear that people finding coins much deeper. Some claim that 8 to 12 inches are possible with this detector. Our ground here in this part of Iowa is almost mineral ( iron ) free, rich loam that is a foot thick not very packed and easy to dig in even in the dead of summer when its dry.
Question how do I get more depth out of this detector? What sounds should I be listening closer for? Maybe I am asking to much out of this old analog detector? Any help or tips will be appreciated.
