Running off 2 x AA batteries (which are included so your doppler will be ready to go when you receive it) this high performance, lightweight device can pick up your baby’s heartbeat from around 12 weeks.

The Sonoline B fetal doppler displays the fetal heart rate (FHR) on a backlit LCD display. It has a built in loudspeaker to listen to the heart rate and an audio socket so you can record the heart beat onto a suitable device to share with friends and family.

 It’s really easy to use. You apply a small amount of ultrasound gel to your tummy (a 250ml bottle is included), and move the probe around above the pelvic bone until you pick up the heart beat and sounds of movement, even hiccups.


The fetal doppler emits and receives totally safe small high frequency sounds waves (ultrasound) which reflect of the fetal heart. Based on the Doppler Effect principles the device uses the differences in frequency and wavelength between the emitted and received waves to calculate the fetal heart rate (FHR).


For home use the fetal doppler can give reassurance between hospitals visits, but obviously should not be used for diagnostic purposes.
