First a little history. I have tried almost all of the pin pointers out there. In my opinion the best for the buck is the Garrett Pro Pointer. There is only one thing wrong with it. Mine and many of yours continue to break or act erratic. I take care of my equipment. I clean it. I don't throw it around, and I never leave it exposed to heat or cold. But this is my third Garrett Pro pointer. The only thing I can think of is that water is getting inside the unit. They go off when I push on them. They continue to beep when I turn it on. So here is my new trial. My Pro pointer inside a 26" bike tube with waterproof silicone tape at each end. The on/off button is real easy to feel and activate. The vibration is still very strong. This thing will clean in seconds. The tape I got at Home Depot. Stay tuned. I'll let you know if I have extended the life of my Pro Pointer.
