Description Extension Probe (optional accessory) The easy-to-use extension probe is attached to treat hard-to-reach areas of the body, such as the upper and lower back when using the Dolphin Neurostim. To use, firmly place the extension cap onto the tip of the unit. Use the tip of the probe as you would the tip of the unit and locate points as described in the preceding section. The extension probe tip is encased in a rubberized material, making the extension probe pliable. This makes it easier to reach points on your neck and back, causing less strain on you as you treat yourself. All extension probes are bendable.
