The NoBark SBC-R uses our Silent Partner™ technology to detect your dog’s unique barking style and delivers a correction only then. By filtering out any external noise, including another dog's bark, your dog receives the most consistent training possible. Now with the option of both long and standard Contact Points, the SBC-R offers 10 levels of static stimulation, as well as 3 programmable modes: Temperament Learning, Progressive Correction, and User-Selected. The OLED display shows the current mode of operation, as well as battery-life status. As a built-in safety feature, if your dog barks 15 times or more within an 80 second period, the SBC-R will stop issuing static stimulation for 30 seconds, and then resume normal operation. In Temperament Learning mode, the correction starts at the lowest level and increases to the next level each time your dog barks within 30 seconds of the previous bark. The collar remembers the correction level needed to stop your dog’s barking. The next time your dog starts barking, the correction will start at the last/highest level used. The static stimulation level will be reduced 30 seconds after your dog stops barking. In Progressive Correction mode, the correction starts at the lowest level and increases to the next level each time your dog barks within 30 seconds of the previous bark. If your dog doesn't bark again within 30 seconds, the correction will reset to the lowest level. In User-Selected mode, you manually choose the correction level. If your dog barks, the collar will correct him at the level you’ve selected until he stops barking.
