What material is the pointer made from?
MIGUEL G It is a light weight metal, very durable. Works well.
JOHN H I think it's brass, coated in some a stainless finish [maybe nickel. However, I do not recommend this product, as there is not place to attach a lanyard. I had high hopes for this as had been looking around for a while since I saw a lot of the DM's in Thailand use them, and really like "muck diving" but it's not what I expected. I contacted Xs Scuba, and they as much as admitted that the design was flawed, and they were looking at a design change to allow a lanyard of sorts to be attached. I would suggest looking around for other pointers.
JOHN M Although not specified, it seems to be made out of brass with a polished coating. It is pretty resilient and sturdy, no issues thus far with corrosion or oxidation with constant use in salt n chlorine water.
