Reliable, solid, and ergonomically designed. This handheld 160 mm unit offers sensitive acupuncture or trigger point location and stimulation. The spring-activated detection probe allows even pressure during searching. Using the sensitivity wheel allows adjustment for dry or moist skin and improves differentiation between closely spaced points. A flashing light and sound indicate when point detection is achieved. The grounding circuit is created by holding the metal plate on the side of the device or by using the hand grounding rod. Pressing the button near the probe provides stimulation. The stimulation intensity is controlled by the rear dial. Pulse frequency is 10 Hz. Accessories include two probe tips (ear, 2 mm and body, 4 mm), hand grounding rod with attached cable, 9-volt battery, carrying case, and instructions. CE197. CE approved and marked.
