As I prepare for my fund-raising triathlon, I've been doing a lot of swimming. One problem that I had to solve was how to swim and monitor my blood sugar at the same time. My Dexcom receiver has to be within 5 feet of the sensor/transmitter. That doesn't work when I'm swimming 1/4 or 1/2 mile distances. While the sensor/transmitter is waterproof, the receiver isn't.I read somewhere about Aquapac and it's line of waterproof cases, so I measured my Dexcom receiver and ordered their mini class case.When it arrived it certainly looked big enough for the Dexcom receiver. But when I tried to put the Dexcom into the case, the face would bind to the plastic. So I took a small index card, folded it, and slipped it into the case first. Then I could easily get the Dexcom receiver in place. I use the index card again when I want to get the receiver back out.When I'm swimming, I use the cord that comes with the Aquapac. I can swim with the cord around my neck, and provided I keep it on the same side as the sensor, I get great readings during the swim. I can also see the values while I'm in the water.For my triathlon, I leave it in the case until the end. That way I don't have to worry about damaging the receiver due to sweat or rain. I've used this case on three long swims (> 15 minutes in the water) and it's worked perfectly. (Source: Bernard's Blog)
