DD-II 330R Non-display Obstetric/Vascular Fetal Doppler (select one of the above probe options; comes with recharger)
Newman Medical DD-330R Non-Display Rechargeable Obstetric/Vascular Fetal Doppler
The Newman Medical DD-330R is a professional-grade audio-only obstetric and vascular fetal Doppler combining exceptional DSC™ sound clarity with the convenience of Newman Medical's Smart Recharging System (SRS™) — so you never have to worry about batteries again. The display indicates battery status, volume, and signal strength without a numeric heart rate readout, making it ideal for clinicians who prefer to assess fetal heart tones manually.
Please Note: The DD-330R does not display a numeric fetal heart rate. The display indicates battery status, volume, and signal strength only.

Superior Sound Quality — DSC™ Digital Sound Clarity
The DD-330R features Newman Medical's state-of-the-art Digital Sound Clarity (DSC™) technology — a built-in sound processor that enhances the sounds you want to hear while reducing background noise. The small but powerful high-fidelity speaker delivers an extraordinarily smooth, rich audio response across the full range of Doppler sounds, allowing you to hear fetal heart tones quickly and clearly.
Fetal Probes with XD™ Extended Depth Technology
All DigiDop fetal probes feature Newman Medical's exclusive eXtended Depth (XD™) technology, generating more than six times the signal at some depths compared to standard probes — without sacrificing sensitivity at greater depths. All probes are fully interchangeable across all DigiDop models for maximum versatility.
- 2 MHz Probes — Excellent deep penetration for late-term pregnancy or larger patients
- 3 MHz Probes — Especially sensitive for early fetal heart detection; suitable throughout pregnancy
- Waterproof Versions Available — Both 2 and 3 MHz probes are available in waterproof versions for water-assisted labor and delivery; easily swapped with standard probes
All probes feature a smooth contour design for comfortable handling, patient comfort, and easy cleaning. The unique magnetic probe holder securely cradles the probe without risk of cracking or breaking, and its open design resists dirt, gel, and germ buildup.
Smart Recharging System (SRS™) — Never Worry About Batteries Again
The DD-330R includes Newman Medical's Smart Recharging System (SRS™), delivering outstanding long-term value through premium high-cycle rechargeable batteries and intelligent charging technology:
- Premium batteries rechargeable over 2,000 times — far exceeding standard rechargeable batteries
- Maintains charge for years when not in use — always ready when you need it
- Smart charging prevents overcharging and detects non-rechargeable batteries to prevent damaging leakage
- Standard micro-USB connection eliminates voltage confusion
- Saves hundreds of dollars over the lifetime of the DigiDop in battery replacement costs
