The Facelake FD-300B Fetal Doppler can meet routine examination requirements of obstetricians, midwives, pregnant women, and vascular ultrasounds. This baby heart monitor is a high-performance model with FHR monitoring and a backlit LCD. Three heart rate processing modes are available to select, including a real-time FHR display mode, averaged FHR display mode, and manual mode. The monitor outputs the digital audio signal through the built-in speaker or via the headphone jack. The audio signal is recognized by standard audio recording software, allowing users to share or save recordings to a computer using the optional recording cable.

The interchangeable probe options are lightweight and ergonomically shaped to fit comfortably in the hand of the user. The 3.0Mhz probe is more sensitive than the 2.0Mhz probe and can pick up a baby's heartbeat as early as 8-10 weeks gestation. The 3.0MHz is an early-term and general-purpose baby doppler probe that will work well through most full-term pregnancies. The 2.0MHz late-term/obese pregnancy probe accommodates depths of 10cm or more.
