The DD-300 is an audio only OB Doppler. The display indicates battery, volume, and signal strength status - DOES NOT display heart rate. The powerful digital processor in the DigiDop utilizes Digital Signal Clarity - DSC to eliminate background noise and amplify a strong clear signal.
DD-300 Non-display Digital Fetal Doppler
These audio only Dopplers provide great value if all you need is to hear the Doppler sounds loud and clear. They include a display of battery condition, signal strength, and volume setting, but do not have a heart rate display.
Superior sound quality
Dopplers have the sensitivity and audio response to allow you to hear the fetal heart tones quickly and clearly. DigiDops have state of the art Digital Sound Clarity - DSC™. A sound processor in the main unit enhances the sounds you want to hear while reducing those you don't. The DSC™ processing is optimally set for each different probe frequency.
The DigiDops speakers are small but powerful high fidelity speakers that have extraordinarily smooth and rich response over the whole range of Doppler sounds.
Built to last
The body is made of a mix of tough plastics with a unique stainless steel grill over the speaker. Latest DigiDop's smooth, clean lines are also more comfortable in the hand. The grill now has micro-screen openings to protect the speaker; the speaker itself has an internal sound transparent fabric cover to keep out dirt and dust.
Unique magnetic probe holder won't crack or break and gently cradles the probe when not being used. The strong magnets use hold the probe without being sensitive to how it's rotated. The open design avoids gathering dirt, gel and germs.
