I recently bought a used "Pristine condition" Nauticam 45 finder on Ebay for a good price that had only been used on a couple of dives. But when it arrived, I was disappointed to find a long obvious crack, the entire length of the inside lens. I contacted the seller, who is also a member of Wetpixel, and he said that the crack was not present when he sent it.
It came wrapped in a thin layer of bubble wrap inside the orignal Nauticam box that was placed in the center of a larger box supported by packing peanuts. I did notice that there was a small amount of room for movement in the inner box and there were no fragile stickers placed on the outside of the box.
So I was wondering if anyone else has had this happen to them when having a viewfinder shipped in the mail, or maybe if the Nauticam finders are particularly fragile. I am actually considering the Inon 45 finder instead now just because of this issue... though I am not sure that it is any less fragile. Or maybe it was just poor packing. Needless to say I am sending it back and getting a refund, but I would like to avoid this a happening in the future.
