Anyone have experience using the navigator after the pin broke off the transmitter? I noticed the pin was broken off of ours last night when I went to put on a new sensor. It seemed fine today but stopped giving readings and went to an hourglass while at the pool this afternoon and hasn't come bacj to giving readings yet after 2 hours. I'm just wondering if this is the end for it finally. We go swimming every day in the summer so if he can't get it in the water no sense wearing it.
