I am going on a cruise in a month and would like to know what parts of the Dexcom can go in water …pools and beaches.
Only the sensor and transmitter… don’t get the receiver anywhere near the wet stuff 
The transmitter (the part stuck to your body) is waterproof but the receiver (display device) is not. When I go to the beach, I usually put it in a waterproof camera case and wrap it up in a light colored towel so it doesn’t get too warm in the sun. Enjoy your cruise, jealous as I look out the window at snow. Dan
I had one Dexcom receiver that got wet from a wave in a Kayak and it failed. I had a second (older) one that went through the wash and it worked fine after it dried out – go figure!
strange!
if it happens again, put the receiver in a big bowl of dry rice for a couple days. It sucks the water out!
Mine went through the wash also and survived. I was amazed.
Although the transmitter is waterproof, unless you get a waterproof bag for the receiver, you won’t have readings during that time - and for my son sometimes if a little water gets under the transmitter it will stop working for a little, but then resume transmitting after it dries out.
I’ve used those before as durable food bags on backpacking trips. They weren’t as durable as I had wished for, but they do last quite a while (at least 10x the life of a regular ziplock.) There’s a kayaking company that makes a thicker one that I might go for, especially since it doesn’t have text all over it.
any recommendations for a bag? I just ordered the akona bag. I am so paranoid that some condensation will get in !
Here’s the one I think I will buy: http://cascadedesigns.com/sealline/protective-cases/e-case/product
I haven’t bought that type yet, but I probably will these season once I start kayaking. I’ve seen them at sports stores here, and they seem very durable and would seal to be waterproof reliably. I’ll report back later in the year when I know for sure.
I did have a few aloksaks, and used them for holding sandwiches and other food things in college. They are essentially a ziplock bag which is quite a bit thicker and has wider seams. They did last a while, but do wear through. They would probably be fine as a water repellent, like if you are in the rain or something splashing. I wouldn’t rely on them for waterproofness though, like kayaking where it could potentially be submerged. Just my 2 cents.
I prefer the hard case for kayaking. I use the Pelican case http://www.pelican-case.com/microcases.html. I find it easier to get things in and out of than a bag.
I went to the store today but didn’t find those specific ones. I got an Aquapac instead. It was the smallest version which I can’t even find on their website, but it holds a Dexcom perfectly. Wast $20
i bought the akona and it holds my meter, strips, pen, pump and camera Ready for snorkeling!
$25 on amazon
i just read in my manual that the transmiter is actually only water resistant, and shouldn’t be in the water for more than 30 mintutes. My daughter does 1 to 1.5 hour workouts in the pool 3 to 4 times a week. she has only had the dex for about 3 months, and so far so good, but does anyone else use it like this? any long term problems?
I called Dexcom too and they said 30 minute max in 3 feet of water. But apparently if you come out of the water at 25 minutes, re-connect it, and go back in it’s okay. As long as you do this every 25-30 minutes. I don’t understand it…
Interesting
I am going on a cruise next month so I am trying to figure all this out
