Hello All,
Haven't even gotten a detector yet,and learned so much from reading all the posts I can,but still have a question.I've seen alot of talk recently about PI detectors.What exactly is PI?I've been looking at getting a Fisher CZ-70 Pro.Does it have it?Do I need it?Any advantage or disadvantages?Thank You all for your time.
