Let me start by saying I'm using a Vaquero detector.....I started using the 5.75 wides an coil which worked very well for me..... I was amazed at how deep it was in my mineralized soil...I continued hearing how much deeper the concentric coils went....... I bought an 8 inch concentric coil for the Vaquero thinking that it would go so much deeper than the wide scan coil.... I checked both coils out in my test Garden ..... I really thought I was going to get a lot more depth with the 8 inch doughnut but it wasn't much more at all .....
Not to mention I was getting much better separation with the small wide scan coil...... this test pretty much convinces me that in highly mineralized soil I'm better off with the double D coil .... i'll save the concentric coil for soil that is not quite so mineralized ..... my next coil will be the 11 x 8 double D coil..... that coil will be by beach coil........Jim
