What's the difference between a G4 and G5 sensor ? I'm in the process of getting a dexcom and I'm very excited! But I don't know much ? Is it water proof ? Do you have to use skin tac?

G4 transmitters last 6 months where G5 last 3 months ... the G5 can be paired via Bluetooth to a phone via the app...., the G4 can't unless it's G4 with share ..... if you insurance is paying for everything I suggest G5 and it is water proof ... I use skin tac because after a few days the adhesive will start to come loose :) also gif grips will help too!

g5 the brains of the operation are all built into the transmitter along with blue tooth. G4 transmitter it just tgat a transmitter, no brains, the receiver has the brains of the operation. a G4 adult share receiver will have the same algorythim as a G5. so we have stuck with the g4 and gotten adult share receivers because the transmitter last a 9 to 13 months in my experience compared to the 112 days max per G5 transmitter.

Dexcom has engineered the G5 transmitter to shut down in 3 months even if the batteries still have a charge.
