Great old coin hunter..... Deep, accurate ID that, coil for coil, rivals my CTX..... Simple to use- turn on, ground balance, and go..... Dual frequency handles bad dirt well & is a must for salt beaches.
Cons:
Nicknamed "The Nail Grabber" by some, due to its tendency to false a lot on deep, pointy iron..... Fairly heavy, and not very well balanced; which makes it feel even heavier. It can be hip or chest mounted but kind of a PITA to use that way...... Concentric coils only, no double D's.
