The backlit LCD shows fetal heart rate in BPM with 1 BPM resolution and ±2 BPM accuracy, so readings are easy to read. Use the display to track changes while you listen on the built-in speaker or headphones.
Designed for home listening from about 12 weeks onward, the lightweight unit is easy to hold and move across the abdomen. Many moms find quick checks reduce anxiety between appointments, while remembering this is not a replacement for medical care.
The sensitive 2.0 MHz probe connects to the detector, with a headphone jack and built-in speaker for private listening. It runs on two AA batteries and has an auto shut-off to save power.
Pick a model that matches how you plan to use it, and understand what it can and cannot do.
- Timing to start: Most devices are useful after the 12th week of pregnancy, when fetal heart sounds become easier to locate.
- Probe frequency: A 2.0 MHz probe is common for routine home listening, balancing sensitivity and ease of use for mid pregnancy.
- Display and audio: Look for an LCD BPM readout plus speaker and headphone output, so you can both see and hear the heartbeat.
- Accuracy and limits: Check resolution and stated accuracy, for example 1 BPM resolution and ±2 BPM accuracy, and remember readings are informational only.
- Power and convenience: Consider battery type, auto shut-off, and probe cord length for comfortable at-home checks.
