I have 3 different pinpointer probes. The first one I got, trying to save money, is a Centech from Harbor Freight. It does work but not very well and for $15 guess you get what you pay for. Upgraded to a Pistol Probe and it is like night and day difference. 5-6" depth means I can home in on the target 99% of the time before even breaking ground. Great probe but at $170 it should be. My other probe, that I have fallen for, is the one you were trying to find in your question. It is the Sun Ray X-1 inline probe for my Explorer SE. The depth is not quite as good as the Pistol Probe but the other advantages make it my favorite probe. With the inline probe all I have to do is flip a switch and lay the detector down to start pinpointing and digging. No removal of headphones since it signals through the detector circuit to the same set I'm already wearing. This also gives me the same disc. sounds I have set on my detector so I don't pick up all the trash that may be close or in the same hole. If I want it to go all metal, like the other probes do, I just push the pinpoint button on my detector and it goes all metal. Never any interference with the detector either since by flipping the switch it turns off the main coil and switches to the probe only. As far as I know, no other probe gives you this advantage plus it is powered off the detector so no fear of not having the extra batteries for the probe. If you are a single detector hunter, I would go with the inline Sun Ray made for your detector before spending $$ on anything else. Having and using multiple detectors, I still like and use the Pistol Probe but have never tried the Garrett Pro pointer which I'm sure is a good tool also.
