cl-510 JM $309 JD $329 The Joey Coil The 5 X 10 inch Joey coil is CoilTek's 2nd best selling coil! Wish you could find small gold and large deep pieces too with your SD or GP? Wish no more! I have found nuggets so small with the JOEY that I can't get them to weigh on a scale! Works great in high mineralization. 13 ounces ! This will be one of your favorite coils.
