Question for MM 722 users

My friend was looking at my insulin pump today and he said that he can make a waterproof case for it. I told him I would post on here and see if there was anyone else that was interested in one if he was able to figure out how to make one.

I remember buying the “sports case” from Minimed back in 2000 when I bought my old 508. I used it once while white water rafting, thinking all was well. I had done everything I was supposed to. The seal was tight. At the end of the trip, I pulled it out and saw my pump floating in a FULL case of water. I’m not sure I’d trust even the Minimed approved guards. But the good news was that after about an hour of drying, the pump was fine and functioned for several more years.
