This is a replacement Minelab lower shaft. Lower shafts can break in the field, so having an extra lower shaft, or even lower shafts on spare coils will eliminate any down time in the field. Highly recommended to have at least one spare if possible. Hardware is not included (rubber washers or nylon nut/bolt). These items are included in Minelab replacement kits on our website.
