The Huntleigh Sonicaid FD3 is a handheld fetal Doppler designed for obstetric use, offering real-time fetal heart rate (FHR) monitoring with a digital display. Equipped with a fixed, high-sensitivity 3 MHz waterproof probe, it ensures reliable detection from early gestation through to delivery, even in challenging cases such as with obese patients. 

Key Features:

• High-Sensitivity 3 MHz Probe: Optimized for early gestation detection, the fixed 3 MHz waterproof transducer is suitable for use in water birthing environments. 
• Digital FHR Display: The large, high-contrast LCD screen provides clear visualization of the fetal heart rate, enhancing monitoring accuracy. 
• Advanced Audio Processing: Features active noise reduction for crystal-clear fetal heart sounds, with both a built-in loudspeaker and headphone output for versatile listening options. 
• User-Friendly Design: Compact and lightweight, the FD3 includes a combined power on/off/volume control, integral probe protection and storage, and a long robust coiled cable for optimal transducer positioning. 
• Power Efficiency: Utilizes AA batteries with advanced power management and auto switch-off features to conserve battery life.
