The Educator ET-400-A is a 3/4 mile range remote training collar that can fit dogs as small as 8 pounds. At just 2" x 1.5" x 1", it's the smallest rechargeable collar receiver you can buy!

E-Collar Technologies' COS ("Control of Stimulation") technology provides very clean stimulation without the normal head jerking found with some other training collars. The ability to set the boost level from 1 to 60 lets you tailor the boost stimulation to your dog's temperament. Smaller dogs typically need 1 to 20 while bigger more stubborn dogs use the 20 to 60 boost range. The "Tapping Sensation" is similar to vibration, but is more intense, making it a good non-stimulation alternative. The ergonomic stop watch style transmitter is designed to be easy to use, letting you watch your dog instead of your transmitter. The night tracking light is remotely controlled by the transmitter and can be set to either flash or remain lit continuously. If you lose or misplace your transmitter, the Lost Transmitter Beeper can help you find it. Plus, the transmitter floats, so you don't have to worry if you drop it in the lake!

    Great Product!!
    September 12, 2020
    This is a repeat purchase for me, 2nd one is the same great quality as the first one. I, unfortunately, “lent” my first one to a friend and his new dog, I never got it back. But he needed it more than I did at the time. Fast forward two years and my “trained” dog started to regress, taking off after any small critter, regardless of cars or any danger. Having it is such peace of mind, I only had to tap her once and she is back to being my good girl. Just putting it on her she is a better behaved dog. She is safe, and I can breathe easily. The product is great quality, and super user friendly for a flute like me. Great customer service too. If you are at all on the fence about this purchase think no more and BUY IT!!
    ProsHigh quality. Easy to use. Great customer service.
    ConsYour friends will want to borrow it. Don't do it!!

    It's a great collar. The best I've ever had. Light and the transmitter is ergonomically excellent. So far, for training all I have to use is the vibrate function. The night light is a great function when walking the dog.

    My Remington has to be the most stubborn dog God ever put on earth!!! I keep the shock between 40 and 50, and so far he comes with just the alert. Occasionally, he needs a reminder, but for the most part he seems to be getting the hint. This collar has been a lifesaver. My neighbor owns a face eating German Shepard, and I REALLY need Remmy to stay in our yard. I would highly recommend this collar to everybody.

    This ecollar was recommended by my trainer Ashley Barrientos and was my first experience with any type of ecollar. My trainer set up the transmitter for me, and took some time to explain how to use it. It is well made and easy to use. My heeler spends a lot of time in the water, and the ecollar shows no damage. His response has been good when in use and is not abusive at the setting I am using.

    I love it. Before I purchased this product my dog was a problem dog. Now that we are using your product, most of the obedience problems have been solved. I would recommend this product. Two thumbs UP!

    This collar has saved my life. I have an American Bully, which is a type of pitbull, and she has an incredible prey drive. Keeping her near me in an unfenced environment borders on impossible if she isn't on a leash. Anyone who knows pitbulls also knows how intense they can get, and the collar helps me snap her out of her hyper-focused state, so I can communicate with her. It is incredible, and I am delighted to have found this amazing product. Easy to use, fantastically smart design. Can't go wrong with this one!!

    Not at all what I intended on getting. Not enough detail on use, and unit dies after 1-2 days. Was intending on returning it.

    After several excursions to the woods, and Beau deciding that he doesn't want to go home, one of which he was missing for 3 hours, I invested in the 400TS collar. I am relieved to know that my pet will not join the long list of lost pets. He now comes back to me w/o engaging the use of this collar. He still wears it no matter what, as I consider it a safety factor.

    Let me start by saying i use e-collars on my dog for everything. My dog is my house pet/outdoor buddy NOT a hunting dog so playing fetch, hiking, mountain biking, backpacking, are things i can say this collar is awesome for.
    I bought this collar as a replacement for my Dogtra 1900ncp and i couldn't be happier. The receiver size is almost half the size of the Dogtra one i own and they seem to deliver the same strength(tested on self, well to 50). I normally used the Dogtra @ 25 and currently use the Einstein @ 16. That being said my dog is a pit bull, well tempered and mainly needs it as a reminder when being stubborn or when off in the distance on a hike or ride. The user controlled light is another awesome feature that works great for night adventures. All is great with this collar, only time will tell for its durability.
