Yes,
The shafts are interchangeable, at Sun Ray they have the pre-mounted probes I can not remember how much they charge if you do not have a core to exchange. It was reasonable I remember because I had just gotten my Safari at the time and did not what to lose it for shipping and install time.
This is one awesome product you will not regret purchasing, I do not think I could own another detector without one. A couple of thoughts to keep in mind however, the control switch mounts mid-shaft on the upper. While the probe is water proof the control switch is only water resistant, this will limit how far you can put your shaft into bodies of water. I have not found this to be a great nuisance since I do not venture too far out if at all. The other minor caveat is that the cord from your main coil will now have to be wrapped around your lower shaft, instead of going through the shaft in the original configuration.
Besides these two minor changes the in-line probe will definitely save you much time pulling your targets. It is a great tool for those hard to find items as you can also use the pinpoint mode to center targets or the depth indicator can help with how far you need to dig (the X1 has about a three inch range).
If you decide to get one I can give you some helpful hints I have found in my experiences.
Good Hunting! Q
