I purchased a Garret pin pointer a good few years back to help me pin point nuggets I was detecting with my my GPX 4500. Unfortunately I wasn’t impressed. It failed to detect small sub-gram nuggets unless they were touching the pointer, and then only marginally. I think most of these devices are targeted at coin and relic detecting where the metal object is a lot larger.
I’m sure it could be useful if there’s decent sized nuggets in the area, but most nuggets seem to be sub-gram in my experience.
Someone here might know about newer pin pointers that are better for gold detecting?
