[QUOTE="Deepseeker, post: 433349, member: 13321"] Thanks for all the replies folks, Actually I think you're on the money Nuggetbuster. Since I last logged in I've been searching online for GPX5000 lower shafts, when it occurred to me to take my bottom shaft off and get something to scrape some of the end of the tube off where it goes into the upper shaft. To my surprise it scrapes off like it's some kind of hard plastic or fibreglass tubing. I was expecting to see the bare silver colour of steel or aluminium once I had scraped the paint off, but no, it remained all black. That surprised me as when i tapped it on the outside prior to my first posting it gave what I thought was a metallic sound. I didn't for one moment think that I may be on to something that the engineers and scentists at Minelab had overlooked, it just didn't make sense to me how it could all work ok if the lower shaft was indeed metal. Thanks for the feedback everyone! [/QUOTE]
