Sonoline C1 Home Ultrasound Fetal Doppler with Backlit LCD Display

Sonoline C1

Sonoline C1 Pocket Fetal Doppler is the perfect tool for fetal heartbeat monitoring with great color display! With the built-in speaker you can hear the heartbeat, kicks and hiccups! In parallel, there is a port for headphones and other audio recording devices. It can be used from the first 10-12 weeks of pregnancy! Sonoline C1 is a compact and energy-saving device that is very easy to use. Two batteries are supplied free of charge! Suitable for doctors, obstetrician, midwives, pregnant women and of course, expectant fathers. It includes a 3MHz probe which has more sensitivity giving a clearer and more accurate monitoring experience.

This fetal Doppler has been scientifically designed to increase the ease of use by expecting moms. Fetal heart rate values, bar graph and heartbeat waveform are all displayed in a LCD screen. The special red-alarming feature helps the moms to know when the heartbeat is going out of range so they can adjust the probe to get the strongest heartbeat.

Why do we recommend 3 MHz probes for fetal heart detection?

Over 90% of OBs, hospitals, and midwives choose 3 MHz probe because they know from the results of millions of exams that 3 MHz works better. It works better because the fetus is so small early in gestation that 3 MHz reflects the ultrasound back to the sensor better than the lower frequency 2 MHz. A 3 MHz has also been proven to work well throughout the pregnancy.


  1. Strong 3MHz probe for a clearer sound output
  2. Powerful built-in speaker for listening the heartbeat without headphones
  3. Large LCD Display
  4. Red-alarm feature which indicates the heartbeats are getting out of range to indicate adjustments.
  5. Uses 2 AA size batteries which are easy to find (2 new batteries are included)- 2 batteries are enough for 15 hours or continuous service
  6. Auto-off feature & low battery consumption to ensures hours & hours of usage
  7. Battery icon which indicates how much battery is left
  8. Headphone jack for listening to the heartbeat
  9. Compact design with buttons which are design to withstand repeated usage without wearing out or breaking
  10. Light and very easy to handle
  11. 3 work modes: real-time FHR display mode, averaged FHR display mode, and manual mode . The FHR can also be displayed in waveform
  12. Auto switch-off

Three Modes

  1. Mode 1: a heart icon is displayed when the heartbeat is detected and the real-time hear t rate is displayed numerically.
  2. Mode 2 : a heart icon is displayed when the heartbeat is detected and it averages the heart rate for a more stable reading.
  3. Mode 3 : this mode allows the user to calculate an average heart rate over a specific period of time by manually pushing a button to start & stop the time.
