Think the ProPointer is mostly brand name and marketing hype. I bought one one impulse, just had to see for myself. Yeah, it was a neat gadget, but hardly worth the price, from an electronics stand point. It failed after 7 months, sent it in, great service. The new one lasted 6 months, before becoming completely useless, in the same fashion as the first. Never sent it back a second time. I can understand a bad production run, or a few bad ones slipping through. A good company would make sure the replacement or serviced product would be perfect. Same problem, seems more like a design flaw, something that should have been corrected. Been using the Centech I had before the Propointer, still does what I need, $17 and a few fun modifications. The case isn't great, but I don't abuse my tools, so it's going to be good for a while.
Been tempted by all the new brands coming out, might pick one up eventually. The TRX seems to be a good choice. Xpointer is still a little new. I really don't need or want a lot of depth from a pinpointer, it's not directional, nor do they discriminate. I pinpoint pretty good with the main unit, and mark the spot, before setting down my detector. I've got a fair idea about how deep I need to go. The soil here is soft sand, no natural stone. Roots are the only obstacle to get in the way. The pinpointer saves me from getting my hands really dirty, and helps avoid hidden sharp items, like broken glass and plastic, iron bits. Not a huge fan of wearing gloves, hands are heavily callused anyway. Just don't see a need for 2 inches+, in a pinpointer, for the way I hunt, and ground conditions. Sometimes, more, is really less than you want or need...
