EZ-904 Easy Educator – 1/2 Mile 4-Dog Remote Training System

The EZ-904 Easy Educator is the ultimate 4-dog remote training solution, designed for intuitive, one-handed control and built-in safety. Based on the proven EZ-900 platform, this compact, powerful system helps you manage multiple dogs with ease—whether you’re at home, in the field, or on the trail.

Each collar receiver features a color-coded strap that matches its corresponding button on the handheld remote, ensuring quick identification and control of each dog. With 100 levels of COS (Control of Stimulation) and a customizable boost level (1–60) for every dog, you can tailor the correction to match each dog’s unique temperament.

Safety features like “Lock and Set” and a maximum stimulation cap prevent accidental overcorrection, while blunt stimulation technology ensures humane, effective results without the harshness of traditional e-collars. For non-stimulation cues, the system includes 7 vibration modes and 4 tone options (customizable via PC interface).

The compact, 2.4 oz receiver is lightweight enough for small dogs but strong enough to handle large, high-drive breeds. Each receiver includes a built-in night tracking light (solid or flashing), easily activated from the remote for enhanced visibility in low light.

Eli ★★★★★

The half-mile range is exactly as advertised—I can work with all four dogs across the field without them noticing the signal. The stimulus levels feel gentle at the low end, and the battery on the handheld has lasted me a full week of daily training.

Jacob ★★★★★

The half-mile range is no joke—I can walk the whole property line and my pointer still responds instantly on the first tap. The one-handed dial is easy to find even with a leash in the other hand, and the four-dog setup means no more juggling separate remotes.

Jason ★★★★★

I’ve been training all four of my dogs at the same time and the half-mile range holds up even when one wanders into the tall brush. The built-in safety feature gives me peace of mind while I’m working with the more stubborn one, and the buttons are easy to find without looking down.
