I'm really not sure I know enough to even ask a question but here goes...... I got my 1st detector, MXT Pro, last fall and a week or so after getting it I had an accident that required arm and shoulder surgery. My MXT Pro came with a 12" coil which is very heavy but I also got the 4x6 shooter coil at the time of purchase. I probably have less than 20 hours of actual swing time but much more than that in reading the forums. I am now able to go out to MD (even though it is snowing today) but am finding the 12" coil pretty heavy. I tried the shooter coil but can't cover much ground. I thought I'd post to see what everyone recomends for a lighter, general purpose coil but while reading I learned that round coils are better for low mineralized ground while double d's work best in higher mineralized soil. Now I AM confused. I live in northeastern KY in a county that has some pretty good coal reserves and a lot of wells with"red" water. I took my MXT Pro out and put it in prospecting mode and it reads 83. Does that mean we have high mineralization? Would a double d coil be better or would a 8x6 sef coil work well? I had originally thought that maybe I should get a 9.5 coil like the one that originally came with the MXT but is that much lighter that the 12"? I really need someone to hunt with but can't find anyone or any clubs in the area. Any help for this newbie will be appreciated!!!!! BTW, all the posts I have been reading has really been helpful, just not on this specific problem! AND please be kind even though tomorrow is April Fool's Day! LOL!!!!
