Rob, Thanks again for getting me my 2 piece upper shaft for my GPX 4000. It works like a charm to be able to break down the detector and store it in the hard case where it is safe. I recomend the Minelab case because it is far less expensive than the Pelican Case and it needs no special work done to the inside to get things to fit properly, you just need the 2 piece upper shaft. I love my Minelab hard case.
