Features

3 MHz probe - All BabyBeat fetal dopplers use 3 MHz probes, proven to pick up those small fetal heart tones earlier in pregnancy than a 2 MHz probe. Over 90% of OBs, hospitals, and midwives choose 3 MHz over 2 MHz (just ask your doctor what type of probe they use).
Excellent sound quality - The speakers inside this Doppler provide a crisp, clear sound while searching for and listening to baby's heartbeat.
