Be careful when using other makes/models of lower shafts with detectors. Although some of them may have the same diameter tubing, the part that goes between the ears of the coils would be wider or more narrow. If it is wider, you could break off one of the coil ears trying to get it slipped in place. If it is narrower, your coil is going to flop around until you tighten the bolt too tight, possibly resulting in a coil ear being broken. In addition, White's uses a holding clip that snaps through two holes on the sides of the middle rod. Minelab uses a single clip design that aligns with holes in the bottom of the middle shaft. So even if the White's rod did fit the coil and the middle rod, you'd have to remove the locking clip, drill a hole in the bottom of the rod and reinstall the clip.
I actually use an Advantage (or Sovereign) lower shaft for one of my X-Terra coils. The tubing diameter is the same and it has the single clip. It is just a bit wider where it bolts up to the coil. But as some folks have expressed, a few of the coils seem to have wider "ears" than others and some have broken off one of the ears while trying to tighten the bolt. I am NOT recommending that anyone go out and buy a Sovereign or Advantage rod to be used with their X-Terra. I am simply stating that I use one with a specific X-Terra coil that seems to have too much space between it's ears. No pun intended. JMHO HH Randy
