At kellyco they sell coils for the Tesoro detectors and it says they give you the option for Coil with short cable or coil with long cable. why do they sell them at different lengths? I'm going to try and answer my own question by saying. the longer lengths cable is for the tall man shafts?? and the short cable is for the standard stock shafts? And what is the proper way to swing a 3"x18" wide scan search coil. What is its purpose. is it a DD configuration?.
