Are the Dexcom transmitters waterproof?

The Dexcom G4 transmitter is not waterproof. However, the Dexcom G4 sensor is water resistant in the shower or bath, or when swimming if the transmitter is fully snapped in. However, the receiver must be kept dry. There is more information available in the G4 Platinum System User Guide.

The Dexcom G5 Mobile System’s transmitter is water resistant. The G5 Sensor Pod is water resistant when the transmitter is installed properly. The receiver is not water resistant or waterproof, and can be damaged if moisture gets inside it. Water can also severely limit communication range with the G5, so you never want to prevent communication between the transmitter and display devices. This can be very dangerous for a patient monitoring their blood glucose. They could miss a severe low or high blood glucose event or make a treatment decision that can result in injury. There is more information available in the Dexcom G5 Mobile User Guide.
