We are now introducing the all-new, 2nd Generation FE-580 FOB Educator® for Big/Stubborn dogs with an optional Finger Button! The FE-580 FOB Educator® 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 and maximum stim levels. Programmable S buttons can be set to stim, rising stim, tone, vibration high, or vibration low. A night tracking light is also supported. Fully waterproof and shock-resistant. 100% Satisfaction Guaranteed. We are proudly assembled in the USA.
