Hey Zach I agree totally with Kent, although I have never had the Tiny Tek I have had the Whites, Pistol Probe which was to deep for a probe and the most expensive of all the hand helds. I have also have the Virbo Probe by Detector Pro ( the same folks as the Pistol Probe) and the my Favorite the Garrett Pro Pointer, in fact I have two of them in case one goes bad, but that a has not happened and I have been everywhere with it including do in the mud and in my humble opinion is the best built by far and is just the right depth for a pin pointer with is about 3 inches. The Virbo Probe is nice, well built and is water proof but only had a depth of only about an 1 1/2 to 2 inches if your lucky, also it interfered with my detectors.
So bottom line is the Garrett and a distant second is the Whites or VibroProbe.
