Pros. It is convenient and reliable at the digging. It has enough depth, static mode. There is a detuning, something average between sensitivity and ground balance. There is a loud dynamic response.
Disadvantages. The most unpleasant drawback of Garrett Pro-Pointer is its Chinese falsification. If you do not know the features (static and dynamic search modes, watch the video), visually you will not distinguish between them. Otherwise, judging by practice, there are no serious shortcomings.
Everything about the Garrett Pro-Pointer pinpointer (including its Chinese falsifications) is compiled here. In my opinion it is one of the most adequate and working pins unless it is made in China))
