This isn't a huge grip or anything, but thought I'd throw it out there having seen it multiple times at this point.
Pre-ordered and received my first X-Terra Pro, and found the head unit had 3 small air bubbles trapped in the display. I thought at first it was just a protective film you would peel off often found on fresh electronics. This was not the case. It was between the plastic lens/screen over the LCD. It wasn't that bad, but noticeable enough to bother me. I tried to move the bubbles and it just got worse.
I sent it into Minelab, and as usual their customer service has always been great for me, and they quickly shipped me a new unit.
The new unit arrive a couple of days later with the same problem. This time the air bubble was almost the size of a dime. I was able to work the bubble out like a cellphone screen protector and fix the display myself. So I'm good and happy now.
While all this has been going on, I watched a video review and noticed someone else had air bubbles in their display! Then yesterday paying more attention here in the original forum post with early pics, it is clearly evident that unit had a another dime size air bubble top center. I'm surprised nobody even mentioned it. Posted here again for viewing.
Having had 2 units myself with the problem, and since seen other units from others displaying the same issue, I'm pretty convinced they have an assembly/manufacturing issue and/or QA problem going on with these. I doubt this will be the last post on the issue. Putting it out there for everyone.
Otherwise, I just don't see a better product at this price point anywhere. Still baffled at how low they went on price considering the tech in the unit. If I was starting out again, I would be so stoked to find this machine on the shelf.
