Features 

Superior sound quality

Our Dopplers have the sensitivity and audio response to allow you to hear the fetal heart tones quickly and clearly. All our DigiDops have our 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

With our industry-leading five-year warranty we have made sure that the DigiDop will stand up to hard use day after day. The combination of our sturdy design and warranty can save you significant service costs.

The body is made of a mix of tough plastics with a unique stainless steel grill over the speaker. Our 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.

Our unique magnetic probe holder won’t crack or break and gently cradles the probe when not being used. The strong magnets we use hold the probe without being sensitive to how it’s rotated. The open design avoids gathering dirt, gel and germs.

 

Options 

Obstetrical Probes

All DigiDop obstetrical probes provide the sensitivity and reliability you need. All probes will work on all DigiDops for maximum versatility. Our 2 and 3 MHz obstetrical probes utilize our exclusive eXtended Depth – XD™ technology that has increased sensitivity at closer depths without sacrificing it at deeper depths. These probes create more than six times as much signal at some depths than other probes. All of our OB probes have a smooth contour design that is comfortable to hold, comfortable for the patient, and easy to clean.

  • 2 MHz probes provide excellent deep penetration for late term pregnancy or larger patients.
  • 3 MHz probes are especially sensitive to early fetal hearts but can also be used throughout the pregnancy.
  • Both 2 and 3 MHz probes are available in water proof versions for water-assisted labor and delivery. These waterproof probes can be removed from the DigiDop and replaced with a standard probe.
  • A variety of vascular probes may be used interchangeably with any DigiDop.

    Warranty 

    Industry Leading Five Year Warranty

    All our DigiDop Dopplers come with a ‘bumper-to-bumper’ 5 year warranty. The warranty includes both parts and labor and covers not just the main unit but also the probes and cords. We can offer this outstanding warranty because our design and materials reduce the number and cost of warranty issues.


    Batteries and Smart Recharge System

    Never worry about batteries again with this outstanding and unique combination of premium batteries and Smart Recharging System – SRS™. We use batteries that can be recharged more than 2000 times – far more than usual rechargeable batteries. This reduces costs and waste significantly. These special batteries will maintain their charge for years when not being used. Our Smart Recharge System charges the batteries quickly but will not overcharge. The system will also detect if non-rechargeable batteries have mistakenly been inserted and will stop charging before causing damaging battery leakage. The DigiDop utilizes a standard micro USB connection so that confusion about whether the charger is the correct voltage or not is eliminated. These advanced batteries and the Smart Recharging System literally save you hundreds of dollars over the lifetime of the DigiDop.

    Made in the USA

    Our products are designed and manufactured near Denver Colorado, a long-time center for diagnostic ultrasound products. Each product, including each probe, is individually inspected and tested to assure quality and durability. We have a very experienced team that has been in the Doppler business for many years – back to the time the first fetal Dopplers were introduced.

    NOT Indestructible and a Nylon Product (NOT A CHEW TOY)
    Color: Green, Color: Green
    I gave this dog toy 2-stars based on my dog toy rating system (DTRS) for “Bruce” the Green Alligator! Unfortunately, I didn’t notice in the fine print of the product description on the website that this toy consisted of Nylon. If I noticed that description, I would’ve never purchased this product. Please do your own research on Nylon wrt teeth. I wasn’t impressed with the toy construction out of the box. The nylon head and tail sandwich the rubber body with soft rubber spines on Bruce’s back for easy gripping. This is not an “Indestructible” dog toy. Safety (1-rating): 1. I was always concerned about my dog’s teeth possibly cracking while he was chewing on Bruce’s Nylon ends. Thankfully, his teeth were fine throughout the use of this toy. 2. The Nylon came off in small pieces after a few hours and continued for the life of the toy; see picture. I never intended for my dog to swallow pieces of Nylon. 3. Bruce’s rubber rear end is where most of the damage occurred, as my dog was tearing off pieces of rubber and spines, which he thankfully passed through his system over a period of 2-3 days after I threw Bruce away; see picture. 4. The chewed-up Nylon ends were very hard, rough, sharp and pointy. There were occasions where I noticed my dog’s gums were bleeding as a result of chewing this toy. 5. Bruce is big enough not to swallow in its entirety, which is why I’m giving this a 1-rating for safety. 6. This is a molded product and not a plush product. Durability (2-rating): 1. It took my dog 1 to 2-weeks to get the toy in the shape that is shown on the posted photos. 2. The Nylon was immediately being scratched and scraped apart on day-1. Then I noticed pieces of Nylon coming off of Bruce after 3-4 days. 3. The rubber was immediately being punctured with small divots around the body on day-1. I noticed over the next couple of days that my dog was focusing on the rear end and trying to pull the rubber off the Nylon tail. 4. The rubber started coming off more quickly after 1-week, until I removed it all together. Squeaker (N/A): 1. Bruce has no squeaker. Fatality (2-rating): 1. Bruce had a longer life than most of my dog’s toys, but then again, I expected this to last much longer as the seller claims it is “Indestructible”, which it is not. 2. I tried filing off some of Bruce’s chewed up Nylon ends to smooth them out for more chew time, but came to my senses and just threw him away for safety concerns only. In conclusion, “Bruce” the Green Alligator should not be given as a chew toy, but more as a fetch toy, unless you want your dog to digest the Nylon and rubber materials.

    My dog loves it
    Color: 1 PC-Beef-Red, Color: 1 PC-Beef-Red
    The bone arrived today and my dog loves it. He is a very aggressive chewer and destroyed almost all his toys so far, even toys that were advertised for aggressive chewers unfortunately didn't held out long, the longest so far was a stuffy we couldn't find anymore and that one lasted him a few weeks but everything else lasted him an hour up to a few days max, even bones don't last him long so we have our hopes set on this bone to satisfy his chewing needs. I will update my review later on sturdiness, since we just got it and I can't review that yet but so far he loves it he has been chewing on it non stop, he already managed to get very small pieces of as shown in picture but with a regular bone he would've already been much much further. The bone is only 10 bucks so the value for money you get based on my experience so far is amazing! But also for this I will come back later to touch upon more. The size is good, our boy is a medium sized dog and this bone was advertised for medium to large size dogs and I thinks the size is just right for our boy . And there is definitely a beef flavor on it you can smell it but it doesn't smell bad it's a nice smell and not very strong but when he is chewing on it you smell it. I would based on my experience so far definitely recommend this bone but also on this I will touch back upon later if it's worth it in the long run. So far a very happy dog and owners here. Edit on May 8th (original review was on March 11th) He still hasn't managed to destroy it it's the first (cgew)toy he hasn't managed to destroy yet which is very impressive since he managed to destroy the even most toughest things we got for him in a week tops and bones within 1, 2 days tops, so we are very happy and pleased with this bone and will definitely get more later. He still enjoys chewing on it and leaves our things mostly alone for some reason he just likes stealing my things and chew on it lol. So 2 months later still stand by recommending this when your dog loves to chew and destroys everything he puts his mouth on.

    Extremely durable, dogs love them
    Color: 2 PC-Beef-Red, Color: 2 PC-Beef-Red
    I was looking for the toughest and most durable dog chew bone I could find and this is it. I have bought multiple other brands that claim to be very durable and tough for a very long time and this is the one for sure. The shower has described this phone accurately and it truly does last. I purchased this bone about 2 months ago. As you see from the photos attached, this is a very well made chew bone and my aggressive pitbulls can't tear it apart do they try. They never get tired of it and chewing it every single day for hours on and keeping them very occupied. I have two bones and three pitbulls that chew on it every day. It is so adorable and has an awesome flavor to it which I think entices them even more to want to chew on it. The durability and Lasting power is amazing to me with these tough chewers. I highly recommend this product to everyone out there. I will say only one negative and that is that the middle wraparound piece they were able to pull off but that is not a big deal because there is plenty of bone which was under that cover in the middle of the bone. There's a few mauled chips missing from the ends but the life of this bone is obviously going to be a long time which really surprised me. Give it a shot if you have heavy duty chewers and you will find how awesome this phone really is and it's durability and strength our second to none in my opinion.

    My dog loves it.
    Color: 1 PC-Beef-Red
    My dog is a super aggressive chewer when it comes to toys. Anything that is soft he rips apart. This one has a wonderful squeaky sound that makes him happy and he enjoys the smell of it. This is a very strong material and definitely worth the price.

    Durable!
    Color: 1 PC-Beef-Red
    Alright, here's a product review for those Tough Dog Toys: Finally, a Toy That Survives My Monster! - Tough Dog Toys Review As the owner of a determined (and I mean determined) large breed chewer, finding toys that last longer than five minutes has been a constant and often frustrating quest. I've gone through countless plush toys ripped to shreds, rubber toys with chunks missing, and even some "indestructible" toys that met their demise far too quickly. That's why I was both hopeful and skeptical when I came across the Tough Dog Toys, designed specifically for aggressive chewers and large breeds. Let me tell you, these bone-shaped nylon toys are living up to their name. My power-chewing Labrador has been going at this thing for days now, and I'm genuinely impressed. Where other toys have succumbed to his relentless gnawing, the Tough Dog Toy has held its own. There are some minor teeth marks, as expected, but absolutely no significant damage, no pieces torn off, and no signs of imminent destruction. "Almost indestructible" might actually be an understatement! The design is simple but effective. The solid nylon construction feels incredibly durable, and the bone shape is easy for my dog to grip and maneuver. It's also a good size for a large breed – substantial enough that he can really get a good chew going without it disappearing in his mouth. What I appreciate most is the peace of mind this toy provides. I no longer have to constantly supervise playtime, fearing that he'll ingest pieces of a destroyed toy. This feels like a safe and long-lasting option for even the most enthusiastic chewers. Pros: * Truly durable – stands up to aggressive chewing from a large breed. * Solid nylon construction feels virtually indestructible. * Safe design with no small parts to break off. * Good size and shape for large dogs to grip and enjoy. * Provides long-lasting entertainment. Cons: * May show some teeth marks over time (though this hasn't compromised its integrity). * It's a fairly hard material, so dogs who prefer softer toys might not be as interested. Overall: If you're at your wit's end trying to find a toy that can withstand your aggressive chewing large breed dog, I highly recommend giving the Tough Dog Toys a try. This bone toy has proven to be the most durable option we've encountered, offering excellent value for money and, most importantly, a safe and engaging chewing experience for your furry friend. Five out of five paws!
