E-Collar Technologies is proud to present the latest tool in our remote trainer lineup! Introducing the all new FE-582 2-Dog FOB Educator® for Big/Stubborn dogs! The FE-582 features our smallest handheld remote and the strongest receiver we’ve ever produced while maintaining an impressive range of up to 500 yards. Of course, it wouldn’t be an E-Collar Technologies remote trainer without our proprietary "blunt" stimulation now available in rising stim mode with user adjustable timing between working level and maximum stim level. Programmable S buttons can be set to stim, rising stim, tone, vibration high or vibration low. Night tracking light also supported. Fully waterproof and shock resistant. 100% Satisfaction Guaranteed. Proudly assembled in the USA.
