Similar to most of our dog remote training products, the ET-800 Remote E-Collar utilizes the proprietary “blunt stimulation” for superior results for low-level stimulation work. However, when high stimulation is needed, the ET-800 Remote E-Collar receiver has the highest stimulation of all the remote trainers in the full dog remote collar market. The ET-800 Remote E-Collar also has the option to choose from vibration or tone for an alternative to stimulation. We are confident that you will be satisfied with the ET-800 Remote E-Collar.
