[QUOTE="Ben78, post: 135559, member: 206"] T6 is just a heat treatment demarcation. The best bet for a detector used in water would be full plastic (glass/frp/carbon) or anodised aluminium. 'Marine' grade aluminium is 5083 and gets a decent oxide layer on it which protects it from the marine environment but isn't particularly attractive. The oxide is what makes aluminium boats turn white/grey over time. For a waterproof enclosure try a piece of PVC pipe, or a Kinchrome/Pelican Case. I am using a lunch box with 'air tight' silicone seal but I am also not chasing waterproofness as my coil is not technically submersible. [/QUOTE]
