FD300 Probe:

FD300 Display:

  • High-performance model with FHR monitoring and a backlit LCD

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

Choosing Probes:

  • 3 Mhz: The 3 MHz is an early term and general purpose Doppler probe. It will work very well through most full term pregnancies. A 3 Mhz is more sensitive than a 2 Mhz probe and can pick up baby's heartbeat as early as 8-10 weeks gestation.
  • 2 Mhz: The 2.0MHz late-term/obese pregnancy probe accommodates depths of 10cm or more.

Recording Cable (optional)

Digital sound recording. You will be able to record those first sounds for life, record your unborn baby's heartbeat. It not only offers digital recording via a computer but also storage on cassette or CD.

Product recommended for new and existing mother's

My 9 year old enjoys hearing the heartbeat of his little sibling. It's fun and easy to use even when I'm on the go. I definitely recommend this amazing product.

Doppler is great

Love it, I purchased it for use on my female Rottweiler, to see if I could tell if she was pregnant! It worked, I hear 3 distinct heartbeats! She get very anxious with loud noises so I have to turn it down, but could still make out the sounds and heartbeats! Very powerful little device! Thank you
