detech 15" DD spiral coil


I got it this morning. After several weeks shipping, I put it on the GPX. I tried it just briefly in test garden. I didn't try any settings other than those published by Hockstetler. When I get the Minelab Commander 18" DD next week, I will try and compare the two. Any one have any better suggestions on settings????? Thanks......

Settings is very much geared to site, targets type and coil size. Don't expect to have the same settings for a very large coil and a small coil.


Hey filternozzle. Can you elaborate. Does the Gain need to be increased or decreased? What else can I do? You know, I am glad that you came back because I couldn't tell a great deal difference between it and the 11"dd. Some louder over the buried 3-ringer but not a lot. On the button back (high tone) sounded a lot better. And a great deal heavier, but the pro-swing made it bearable. Thanks....
