I have seen some MD using the sunray inline probe and wondered whether it really added much of a benefit to their machine. I use a DFX and considered one of these but have never been around anyone that thing to be able to try it out myself.
You get a big giant yes from me.
I have 3 Minelab detectors and i have probes on all of them.They save a lot of time and digging.
I would whole heartedly say get one if you can.....
