I have used both models of the Garrett pin pointers over the years. I think I had 3 Pro Pointers before finally purchasing the Garrett Carrot, (AT Pointer).
When my original pin pointer developed problems, I called Garrett. I was given a "Return service number," and sent it in. Garrett
just about rebuilt it, as it came back looking brand new. I have since had another of the black units rebuilt and again the service was
fantastic. I have never had any problems with the Garrett Carrot, (AT Pointer).
I always covered the Black unit's speaker with red plastic electrical tape. It helps to keep dirt out while protecting the unit from water
during use in the rain. The Red Tape also makes the pointer easier to spot in case you put it down in the grass while digging, and
then forget to pick it up. On the black unit (pro pointer), mud will tend to foul the on/off button. You can carefully remove the rubber
button and clean the area just above the internal white button switch. After cleaning the black rubber switch cover, it can be easily
reinstalled. Sometimes the pointer will act erratic by either giving false signals or just beeping for no reason. In both cases, try changing the battery.
After many years of hunting with a technique known as, "Waving a fistful of soil across the Coil," I will not leave home without my pointer.
