Badd ground DD vs concentric coil

[kaolinwasher]

You have heard it said , DD coils do better in mineralized ground , well hear is a test i took the 7" DD wich has less winding , and put it up against the 8" concentric and put a U,S dime at a good depth but gettable for shure 5" deep the dirt road is composed of class 5 gravle and it is loaded with basalt and magnetite , and it looks like the DD did do better in this ground , so dont throw away your DD coils , but dont throw away the concentric they are both good coils just use them whear they are strong and you will be doing good , Gunnar spencer brook MN[video]http://www.youtube.com/watch?v=1sPHI2Dalpc[/video]

Nice videos as always but what effect does threshold have in discriminate mode

 

[kaolinwasher]

what efect does threshold have in disc mode? It seems to amplify the signal , and make it louder , works best at 1 to 3 PM in the dial

Gunnar thanks for sharing your videos. I'm glad that I live in an area that has mild ground. It makes all the difference in the World.
