E-Collar Mini Educator ET-300 – Remote Training Collar, 1/2 Mile

E-Collar Mini Educator ET-300 – The Best-Selling Remote Training Collar

The ET-300 Mini Educator by E-Collar Technologies is a remote dog training collar — and the best-selling, most trusted model among professional trainers in the Educator series. The compact "stopwatch" transmitter is designed to sit naturally in your palm and be operated without looking, so you can focus on your dog instead of the remote.

What sets the ET-300 apart

The model uses COS technology and smooth, stable "blunt" stimulation — 100 graduated stimulation levels for precise tuning to your dog's temperament, plus a Boost (1–60) for high-distraction moments. Lock & Set locks in your chosen level and prevents accidental changes. It also includes a Tone button and Vibration for gentle warning before stimulation, a Pavlovian Tone feature for training to sound alone, and a night light (steady or flashing) operated from the transmitter to locate your dog in the dark.

Who is it for?

The RX-090 receiver weighs about 2.4 oz — light and gentle enough for small dogs, but strong enough for larger ones. Collar and transmitter are fully waterproof (the transmitter even floats), so you can work in any weather and around water. Recommended experience level: beginner through advanced. Expandable to two dogs with an additional receiver.
