Well after waiting for so long and hoping that my last hot'n tot would not get snagged up they finaly arrived. The new brads diver!!!! Yahoo!! so I go out and buy 10 of them. To date 5 of them have filled up with water and sunk. two have made it back to the boat. Well after carfully looking at them I find that there is a small gap between the bill and the body. That is where the water is getting in. The good news is that Brad knows about the defect and is working on getting it fixed. Also they will give you a new one if you take your water logged one back.
It is also a quick fix a small bead of glue or caulking will do it. I must say some others I know have also bought some and have had no problems. I must have gotten a bad batch.
So check them before you dive them

Thanks for the headsup. I have not used mine yet. Looking at mine I can see the gap you are talking about. I will seal it before I use it.
