Huntleigh FD1+

Suggested Retail Price $650

According to Huntleigh the FD1+ fetal doppler is one of if not the most trusted and widely used fetal dopplers worldwide. Our Huntleigh test units where generously donated from Stork Radio.com who is one of Huntleigh's largest distributors of its FD1+ and D920 models.

The FD1+ is the digital fetal doppler unit in Huntleighs Audio Dopplex line which means it displays the fetal heart rate in real time on a small easily readable LCD display. This fetal doppler comes with a permanently attached 2MHz probe which we prefer to a 3MHz probe... Most medical grade obstetric fetal dopplers on the market come with either a 2 or 3MHz probe (link to section on probes) for monitoring the fetal heart rate. Understanding the difference between the two is fairly important as they both have recommended uses even though the 2MHz tends to be the better all around probe.

We tried the FD1+ fetal doppler at a number of different stages of pregnancy. First at 8 weeks, when much of the advertising around this unit states you can begin listening. We couldn't find the heartbeat at 8 weeks on our first patient but found it easily on others. Finding the heartbeat this early depends on many factors only one being the quality of the doppler which in this case is not in question. Our experience tells us that most reasons for not finding the heartbeat this early in pregnancy have to do with such factors as user error, position of the uterus, or a possible miscalculation of gestation. Following our 8 week exam we tested the unit every week for the next 32 and were extremely impressed with the results. Other than the few instances early in pregnancy (8 weeks) where it took us a few minutes to get the probe angled correctly and hear the heartbeat the Huntleigh FD1+ lived up to its billing and was a pleasure to use. We gave the Huntleigh our highest rating out of all the fetal dopplers we reviewed a 10 out of a possible 10. All scores take into consideration price, design, ease if use, sensitivity, sound and durability.


The FD1+ fetal doppler is made of a three piece casing of ABS polycarbonate alloy (front, back, and battery cover). We found the overall design of the unit to be very pleasing and easy to use. The transducer fits securely into its recessed housing and is easy to extract. When the probe is put away the unit is very compact and much less cumbersome than other doppler models from Nicolet and Summit . Holes in the front cover resemble buttons and work very well to protect the speaker and allow the sound to resonate. The volume control found on the side of the unit has a great range and is easy to adjust with a free finger while in use. We really liked the larger than normal size of the FHR (fetal heart rate) display which made the very concise readings extremely easy to read. The power button on the front lower left is large and makes turning the unit on & off a breeze.


Note worthy features of the current production of the FD1+ fetal doppler is its standard waterproof probe which is very useful for water births. The FD1+ is the only fetal doppler on the market to offer this as a standard feature. The FD1+ has a low battery indicator which appears in the shape of a battery on the digital display when battery needs replacing. An automatic shut-off function comes in very handy for battery preservation. After one minute of no signal or 5 minutes continuous operation the unit automatically shuts down. The standard headphone jack found on the left side of the unit can be used for connection to a tape recorder or battery powered laptop computer for recording the fetal Doppler audio signal.


This fetal doppler has a 2 year warranty on parts exclusive of cables and crystals which are 1 year.
