The Omnipod will fail if you use it for SCUBA. It will also fail if used for any type of diving; even the limited depths that can be achieved without weight when snorkeling when I do enough dives. It’s the up-and-down that matters most but at SCUBA depths one down may be enough.
The CGM is invaluable. It makes boat dives so much easier; just a matter of pulling out my 'phone when on board. Trying to do a fingerstick on a rocking boat while being sprayed with surf can be challenging.
Some divers have used the G6 underwater, using a 'phone in a suitable enclosure and holding it close to the G6 to get the reading. The G7 is likely to be even more waterproof than the G6 because it has absolutely no external electrical connections.
I always carry glucose gel when diving and for other water sports; two tubes in my BCD, two carried by my wife. I’ve never had to use one and the last forever.
For ocean swimming the G6 really doesn’t work well if it stays underwater and you want to count on a reading or a reading any time soon. I’ve tried keeping my phone right next to the Dexcom and it’s very erratic and hardly ever works. I’ve tried lifting my arm out of the water for 5-10 minutes and no. Once it loses it’s signal for any length of time it takes forever to reconnect and download it’s data before it will give you a reading. That’s why I started wearing a Libre as it can scan and get an instant reading. But it won’t work below a certain depth or if it’s too cold. I’m not sure how cold is too cold as I’ve never had to deal with that.
Ah Yes! You are so right. The Omnipod will not work or even be destroyed at depths lower than swimming pools! I, too, carry squeezable glucose but have used it only once! Glucose tabs when back above water are my go to! But lunch helps too! SMILE
Yup. i agree with all this. You aren’t gonna be underwater long enough for a lack of insulin delivery of this to matter. Test this by doing some swimming in the short term (weeks) before you dive.
You sure have lost a lot of pumps in all terrain sports, John.
I would not recommend using any pump at pressure. Remember the siphoning study? It’s not tested for that.
I’ve only ever used xDrip+ for the “smartphone” connection and, yes, at times after a dive it feels like forever but in similar non-water situations I’ve seen that both the G6 and G7 reconnect reliably with xDrip+ on Android at the first five minute slot (the transmitters only switch on every 5 minutes after the first connect). A finger stick is often faster in good conditions (not on a boat etc.) It’s faster 90% of the time on average based on 30 seconds to do a fingerstick.
My experiences are based on being in a very quiet wifi environment; even on boats. In airports on the contrary they mimic yours. Reconnecting to a Dexcom after arrival at San Francisco Airport is almost impossible. Of course it is possible to fry a chicken by holding it in the air and saying “Bill Gates” in SFO.
The G6 but maybe not the G7 “drop” the connection after 30 minutes, so a 60 minute dive means no connection to the transmitter (though the diver who took her 'phone down with her might not have had this problem). Reconnection requires that the transmitter consider every incoming bluetooth connection however the G6 only did the reconnect every 5 minutes and, so far as I can determine, the G7 is the same. In other words both only “wake up” every five minutes when they have a new reading but if they are disconnected I hypothesize that they accept connection attempts indiscriminately, rather than being bound to the previous connectee.
PITA in SFO, no biggy on a small boat in the middle of the Caribbean. Desperate Diabetic Death on a cruise ship.
I’ve only used the Omnipod. I did meet one guy who dove with the other under-water capable pump (can’t remember the name) but that has been discontinued in the US.
I don’t recommend or not; I’m just saying I tried it and it didn’t work. I don’t recommend repeating my experiments but then I don’t recommend trusting my results. Now what is it about Madame Curie’s fingerprints that I read recently?
Don’t do what scientists do. Simply trust or dispute the result.
