The ET-300 Remote Training Bundle also comes with a PetsTEK dog whistle kit and dog training clicker. This combination is usually designed to provide the pet owner with a set of helpful tools to train their dog new behaviors.

Generally, it’s one of the most innovative training collars which are equipped with the newly enhanced and lightweight receivers. The collar weighs 2.4 oz., which is pretty light and includes a strap for easy fastening.

The pet owner can control the puppy up to half a mile away. That makes the pet training kit an excellent option for use on parks, back yards, competitions, extensive field training, and different types of hunting.

The training system is designed to work and also ensure positive reinforcement after every use. It doesn’t require lots of experience to use, particularly when it’s combined with the dog whistle kit.

It enables the pet owner to train their dogs to full potential. It’s widely known that a dog does not only have a good sense of smell but of hearing too. With your whistle kit, the puppy will be a bit easier to control when compared to the human voice.

Main Features

The Educator ET-300 is an electric pet training system that’s packed with a lot of impressive and unique features that you will rarely find with the competitors’ models.

Manufactured and also tested in the United States, this five stars rated training collar is a perfect selection for pet owners who would like to solve behavioral issues, teach obedience, or just give their puppies more freedom when walking without a leash.

Here are some of the amazing features that make this training collar one of the most versatile dog training bundles on the market.

Lightweight design: The Educator ET-300 collar weighs only 2.4 oz., which makes it the smallest model on the market today and a perfect training option for small dogs that weigh around 5 pounds. However, you should not be fooled by size because it can also be used for bigger breeds that have normal temperaments too.

Adjustable collar strap: The ET-300 collar comes with a fully adjustable strap that’s made from long-lasting Biothane. With only a width of ¾ inches, the collar can be adjusted to custom fit dogs that have neck sizes that range between 3 inches and 29 inches.

Control of stimulation (COS): The COS features usually offer pet owners the ability to choose a certain level of static stimulation that is best suits their dogs. This dog collar is effective and pretty safe for all dog breeds with normal temperaments and provides you with 100 different stimulation levels to help you fine-tune the stimulation level that is ideal for your pup. The COS technology is quite reliable, giving a tapping sensation instead of a vibration that most people claim it works pretty well.

Lock and set function: The “Lock and Set” function is one of the best safety features of this dog collar and is exclusive to all Educator brand collars. This feature allows you to set the stimulation level that best suits your dog, and also lock it in to prevent over-stimulating your dog accidentally.

Adjustable booster function: The booster function is useful when you feel that your pup needs an extra boost to get its attention. This feature is fully adjustable with many settings that range between 1 and 60 on the training system. It enables you to easily get the attention of your dog, even in extremely distracting environments or circumstances.

Wide pulse stimulation: One of the most excellent features of the ET-300 training collar is the wide pulse or blunt stimulation. This cutting-edge feature assists in making this training system one of the most sought-after collars on the market. 

Instead of the traditional sharp stimulation provided by other dog training collar brands, the blunt stimulation offers a cleaner, less stressful and medical-grade stimulation for your dog. With this kind of stimulation, you will not see your puppy wincing or jerking its head during obedience training sessions, as many people experience with competitors’ training collars.

Night tracking light: The other amazing safety feature and an incredibly essential feature that is provided by this training system is the effective night tracking light. You can conveniently control the light using the remote transmitter, which means you can turn it on and off at will. 

This feature is a great thing for dog owners who regularly train in dimly lit places or during the night. It will not only assist you in locating your dog in the dark areas, but it will also help other people and cars see your pet as well.

Waterproof with a floating transmitter: The ET-300 dog training system is fully submersible in water up to 500 feet. Therefore, water training, swimming, and training in extremely wet conditions can never be a problem.

 Besides, if you also get slippery fingers or hands from time to time, you will not have to worry about your transmitter getting lost in lakes, streams, and rivers because it’s designed to float on water.

Two-hour quick charge: In most cases, standard dog collars take many hours to charge, but the ET-300 model takes only two hours to get a full charge. It is equipped with several Li-Polymer Rechargeable Batteries that you can fully charge in only two hours. 

With the option of a vehicle charger, low-battery indicators on the two units, and a two-year warranty that includes all the batteries, you will never miss a training session because the training system has run out of power.

Pavlovian Tone: The Pavlovian Tone is a great feature for training, and it creates a 1 to 1/2 second tone, the set stimulation follows that. Therefore, the puppy will soon learn to respond to that tone only. You will also have the opportunity to select your preferred levels of stimulation to get the targeted results.

Simple and easy-to-use buttons: The ergonomic and simple design of the remote transmitter is something worth noting, and the features it provides are matchless. In addition to all the features mentioned above, the ET-300 comes with three simple buttons on its remote; momentary static mode, continuous static mode and vibration only mode.

The vibration mode feature allows the pet owner to give the dog a warning signal before initiating static stimulation. It can be an effective tool, especially when training dogs that are sensitive to stimulation or deaf pets.

The momentary mode is only beneficial when you want to get back your dog’s attention when it gets distracted by moving vehicles or squirrels running across your lawn. The continuous mode is useful when you want to give your puppy constant static stimulation that lasts for a maximum of 10 seconds.


  • It has a lightweight design.
  • It provides stress-free blunt stimulation.
  • It comes with an ergonomic, waterproof transmitter.
  • It includes a convenient night tracking light.
  • It includes a Pavlovian tone.
  • The COS technology provides a tapping sensation.
