Anyone have one or thinking of getting one? I bought the sonoline b doppler a little over a year ago and I finally pulled it back out yesterday and I found the h/b at 9 weeks! My RE showed me exactly where to look and I was able to find the h/b within 30 seconds. It's going to be really hard trying not to use it every day. I'm just glad I have it to ease my fears between u/s.
