Keene 151S Boxes in GOLD PROSPECTING Posted May 6, 2019 · Edited May 6, 2019 by Relichunter2016 Well the more I work with these boxes and trays the more I realize that Keene modified the trays and never changed the boxes.I can understand that redoing the molds to the box to accommodate the tray mods would be costly. But the new trays do not fit the boxes..hence I am having a hell of a time with it. They went from the old black screen to silk screen, than added a foam similar to that stuff you put at the bottom of kitchen shelving, than a plexi-glas sheet to the bottom of the riffles that are screwed and than a separate gray in color matting that goes on top of the box between the tray and box. When you try to slide the recovery box its a huge problem, it don't fit! They should have redone the box to accommodate the new dimension of the tray. This project cost me a lot of money..I was going between the Royal box which would have cost me around 375.00 a piece and I choose Keene based on reputation...550.00 per box X 5 plus shipping 3,500! Well now I am really sorry I choose Keene...its seriously;y is not worth the hassle...When I sent a message with pictures to Pat, he never responded. This was a disappointment...anyways live and learn. I may have to just remove the plexiglass, the foam, and extra gray matting so it fits into the box and just slam it in...and go with what I have this season. I don't mean to Bitch about Keene, they have provided the prospector with some great equipment .but this new moded out tray sucks big time.
