The FD320 Fetal Doppler features a high-resolution LCD for displaying a real-time FHR waveform and fetal heart rate reading. The doppler uses premium components such as an ultrasonic signal transmitter and receiver, an analog signal processing unit, FHR calculating unit, and an LCD control unit, etc. The unit's color-coded alarm feature automatically alerts to FHR measurements detected outside the normal range. Interference-free audio output through the headphone jack allows for clear audio recording and supports external headphones or speakers.

The FD320 has three working modes: real-time FHR display mode, averaged FHR display mode, and manual mode. This baby doppler also includes continuous monitoring for up to 8 hours of working time usage. The water-resistant probes are interchangeable and can be chosen based on the requirements of each user. For most full-term pregnancies, the 3.0MHz probe suits most early-term and general-purpose pregnancies. The 2.0MHz late-term pregnancy probe accommodates depths of 10cm or more.


Three Working Modes:
  • Mode 1: A heart icon is displayed when the heartbeat is detected and the real-time heart rate is displayed numerically
  • Mode 2: A heart icon is displayed when the heartbeat is detected and it averages the heart rate for a more stable reading
  • Mode 3: This mode allows the user to calculate an average heart rate over a specific period of time by manually pushing a button to start & stop the time

Features:

  • FDA & CE Approved
  • Listen through the powerful built-in speaker or with headphones
  • Easy to read LCD screen with on/off back light mode
  • Digital fetal heart rate displayed
  • Auto-off feature & low battery consumption to ensure many hours of usage
  • Battery icon indicating remaining battery life (AA batteries)
  • Weighs less than 1/2 a pound
  • Compact design with buttons designed to withstand repeated usage without wearing or breaking
  • * Recording/Audio Cable is optional


  • Includes everything the FD300 has above, but FD320 in addition has:

  • Colored LCD high resolution display
  • Heartbeat wavelength display and bar graph
  • Color coded alarm changes to red when the fetal heart rate range is out of the normal range



Choosing Probes:

  • 3 Mhz: The 3 MHz is an early term and general purpose Doppler probe. It will work very well through most full-term pregnancies. A 3 Mhz is more sensitive than a 2 Mhz probe and can pick up a baby's heartbeat as early as 8-10 weeks gestation.
  • 2 Mhz: Designed to accommodate late term pregnancies since it works best at 10 cm and larger depths.
  • 8 Mhz: The 8 MHz probe is designed for Vascular monitoring and provides vein blood flow and artery detection. This probe provides the highest resolution and detects a broader range of frequencies than the other probes. The probe's intended use is for examining surface vessels.

Our Dogs Are Obsessed. The Squeak Is Intense.
Style: Large Ball, Size: 3 Count, Style: Large Ball, Size: 3 Count
BLUF: Our dogs absolutely love these — the squeak is loud enough that we sometimes have to take them away. --- Our dogs went crazy for these the moment we opened the pack. They’re durable, super bouncy, and easily became the new favorite toys in the house. The only thing to know is that the squeak is loud — like “I need to take this away for a minute” loud. But honestly, that’s probably why the dogs love them so much. Great value for a 3‑pack and perfect for pups who enjoy a good squeaky toy.

A great toy for any dog!
Style: Small Ball, Size: 1 Count, Style: Small Ball, Size: 1 Count
The Hartz Duraplay ball is great! My 4 1/2 yr. old Pug has never liked playing with them before. He has gone crazy for this ball. He has no trouble grabbing it with is mouth. He ever gets it to squeak with his feet. I think it’s a great dog toy. Excellent!

Great Value and very durable
Style: Small Ball, Size: 1 Count
Very durable! We have purchased this for our new lab puppy. Highly recommend them. We have bought them before for our retrievers and it has been one of the longest lasting toys they own. Which says a lot because toys get torn up fast in our house. Definitely a good value and the material is easy on their teeth. Also it keeps ours busy for a while.

Aussie Approved
Size: Large, Color: Blue
I got a knock off one of these originally and man I should have just stuck with the real thing. My dog destroyed the other one in about 4 seconds. My dog loves this one and has not been able to tear it up, he prefers to just push it around after he gets all the treat out of it which is hilarious to watch. The quality is amazing and it is so easy to clean without leaving a smelly odor on it. It fits in my freezer perfectly and also is soft but firm so I do not have to worry about my dog hurting his teeth. For reference I have an Aussie and I got the large one which is perfect for his size (60lbs). My pet prefers this one over the last one for sure since this one actually keeps him entertained.

Awesome enrichment toy!
Size: Large, Color: Green, Size: Large, Color: Green
These are awesome! My dogs love them and keep them occupied for 30-60 mins so I can make and enjoy my coffee in peace before work. They are very easy to clean, but as others have mentioned, they can get stuck. I had to take a pliers to get one of them unscrewed. Hopefully that’s not a constant issue. I do wish they were more durable since there were a lot of teeth marks in them after the first use, so I upgraded to the black super chewer one. I’m happy I gave these a try and feel they are worth the money, especially for high energy dogs who get bored easily.
