E-Collar ET‑300 Mini Educator Remote Dog Training Collar – ½‑Mile Range, Waterproof, Rechargeable, 100 Stimulation Levels, Tone & Vibration, Black

The Educator ET‑300 Mini Educator (Model ET‑300) offers professional‑grade remote training performance in a compact, ergonomic design ideal for dogs 5 lb and up. Built for comfort and precision, its small transmitter is perfect for smaller hands and discreet one‑hand operation. Featuring a ½‑mile reliable remote range, this system enables you to maintain control across open fields, backyards, or training areas.

Training with the ET‑300 means access to 100 levels of smooth, patented COS (Control of Stimulation) static stimulation, plus a boost function (levels 1–60) for high-distraction environments. Its tone and vibration modes—including Pavlovian tone conditioning—allow effective communication before the application of stimulation

Built for real-world use, both the remote and collar receiver are fully waterproof (up to 500 ft), and the remote even floats if dropped in water. The system is rugged and shock-resistant for over 5000 G‑force conditions. The built-in LED tracking light offers stable or flashing modes for enhanced nighttime visibility.

Recharge quickly with the 2-hour lithium‑polymer battery, offering 40–60 hours of standby time. An indicator alerts you when the battery runs low. The Lock & Set dial lets you lock each dog’s stimulation level for consistent, no-look operation. Easily expandable to a two‑dog system with an additional receiver (ET‑302, sold separately). Proudly assembled in the USA and backed by a 2‑year warranty, it’s a durable, effective solution for everyday training, obedience, and off-leash safety.
