OverviewAUVON Live Smart, Live Healthy AUVON TENS Unit The TENS machine is safe, non-invasive, method of pain relief and pain management. Many people have even used it for intense pain from sports injury, knee injury, foot, hip, arthritis or tennis elbow. Do I need independent intensity controls for each channel? Most of dual channel TENS units (muscle stimulator for pain) on the market today have independent intensity controls for each channel. What this means is that you can increase and decrease the "massage" strength / intensity separately within the channels. The major advantage with a dual channel device is that you can "massage" two areas (or sides of the body) simultaneously. With a single channel unit you are limited to one area for a comfortable feeling. What are fully isolated channels? Fully isolated channels enable you to run separate programs in different channels, rather than just control the intensity for the channel. This is a quite a recent development and can be found on this AUVON dual channel TENS machine. For example, you could choose Acupuncture mode in channel 1 with an intensity level of 5 for your shoulder. While in channel 2, the Tapping mode is being run with the intensity set to level 10 on your back. In this condition, you will never worry about the strength is too weak on your back while too high on you shoulder where you feel more sensitive.
