My Harbor Freight Pin Pointer finally broke on me after about a year of use. I want to get a good pin pointer and I have come it has come down to the Garret or the Mine lab. Which one should I go with? It seems like everyone goes with the garret but I see that people say a lot that it works good when it is working, I don't really want to pay $150 for something that will only work half the time. I have not found many reviews on the mine lab, can anyone tell me more about it? is it built better than the Garret?
