When something doesn't work to par, the first thing I usually hear is "it must be a defective unit". Same with detectors.
Skippy has pointed, and I have read, other people having the same results. I appreciate the heads up telling me what I "can" expect from the status quo. Personally, my XPointer works flawlessly. So Deteknix "has" the ability to make a good pinpointer. So, in retrospect, the review was educational and not meant to be demeaning. It served it's purpose, and Deteknix is aware. A good example of the community and manufacturer working toward a positive solution. Time will tell, but patience is required.
Just my opinion.
