The Huntleigh Audio Doppler D920, an audio-only obstetric Doppler with a 2mhz waterproof probe that is designed specifically for routine use in the second and third trimester, as well as use during labor. Its fixed 2 MHz probe is enhanced with active noise reduction features to produce clear fetal heart tones in and out of water. Increased probe sensitivity enables the Huntleigh D920 to detect a Fetal Heart Rates (FHR) as early as 10-12 weeks and its built-in shock resistance on the probe helps protect against bumps or jostling.

The D920, with its high-sensitivity 2MHz probe and excellent audio quality, ensures easy and reliable detection throughout pregnancy.
