Huntleigh Sonicaid Pocket Fetal Doppler FD2 Rate Display Doppler Review

Add to compare

The Huntleigh Sonicaid Pocket Fetal Doppler supports a variety of different venous functions while remaining completely compact. It’s one of Huntleigh’s many handheld dopplers available in the market. So, just how does it compare? More information on that available below.


As a handheld Doppler, made for on-the-go assessments, there really isn’t that much to speak of in terms of big features. Nevertheless, we’ve listed most of the Sonicaid’s relevant characteristics below:

  • Micro-monitor for displaying recorded heart rate.
  • Interchangeable probes. It accepts both a 2 MHz doppler (waterproof) probe and a 3 MHz doppler probe for obstetric ultrasounds and the detection of fetal heartbeat, respectively. Vascular dopplers are also compatible (five different frequencies available.)
  • The Sonicaid can also be connected to a Dopplex Printa in order to print recorded fetal heartbeats in real-time
  • Automatic Switch-Off feature for conserving battery life and an audio output port for connecting to headphones or speakers have also been included for maximum convenience.

Tests Performed

The Huntleigh Sonicaid was meant to be both a Fetal Doppler and a Vascular Doppler. The interchangeable probes allowed for that multi-functionality. Its 2 MHz probe, as mentioned, is meant for obstetric ultrasounds, whilst the 3 MHz probe is made for general fetal heartbeat examinations. They’ve included a heartbeat display monitor as well to make both functions as easy as possible.

As for its use as a vascular doppler, five other frequencies have been provided to allow for maximum detection — for surface level arteries and for arteries that are deeper in. Of course, it’s not the most complex ABI doppler out there — it’s meant to be used as an audio-only pocket doppler (either through the built-in speakers or after connecting to the provided audio-output jack), but it works fine in manual application.

Huntleigh Sonicaid Pocket Fetal Doppler FD2 Rate Display Doppler Review

All in all, there is no denying that the Huntleigh Sonicaid makes for a very good pocket fetal doppler. It does what it was meant to do and provides functionalities that allowed for a lot of flexibility. Of course, it’s not much when compared to other ABI systems in the market, but it can get the job done.

Pros and Cons

A list of pros and cons of the Huntleigh Sonicaid Pocket Fetal Doppler FD2 Rate Display Doppler System.


  • The best feature provided by the Huntleigh Sonicaid is definitely the Doppler Connector. With it, the probe can be used as an obstetric ultrasound Doppler, a fetal heartbeat monitor doppler, and a vascular doppler.
  • It was built to be very convenient as well, with the micro-monitor display, the built-in speakers, and the audio output port.
  • Huntleigh’s additional smart features, like the compatibility with the Dopplex Printa systems and the Automatic Switch-Off feature, also offers some extra convenience that isn’t necessarily available in other pocket dopplers.


  • A pocket doppler is meant to be compact and efficient, and that’s exactly what the Sonicaid is. It does what it is meant to do. However, there’s no denying that there are more advanced systems available out there that this pocket doppler couldn’t possibly compare to (especially not the more automated ABI systems.)
