E-Collar Educator ET-400 – Remote Training Collar, 3/4 Mile

E-Collar Educator ET-400 – Versatile and Powerful, 3/4 Mile Range

The ET-400 Educator by E-Collar Technologies is a versatile, powerful remote dog training collar. It's built on the familiar ET-300 platform, but with a larger transmitter and an improved internal antenna that deliver a range of up to 3/4 mile — ideal for field work and longer distances.

What sets the ET-400 apart

The extended range is the main differentiator from the ET-300. Beyond that, the model carries every advantage of the series: smooth "blunt" stimulation with 100 graduated levels, a Boost (1–60) for high-distraction moments, Tone and Vibration buttons, Lock & Set, and a night light (steady/flashing) operated from the transmitter.

Who is it for?

The light RX-090 receiver (about 2.4 oz) is gentle enough for small dogs but strong enough for large, highly motivated ones. Waterproof. It suits a wide range of sizes and temperaments, and especially situations that call for longer-than-usual control range. Expandable to two dogs with an additional receiver.
