JDV Products' Ion Gun with Light Beam, No. BBZ-E, does not have bulky external transformers and its electrode needle will not break easily if dropped because they are not exposed. Combining accurate ion balance (around +/-15~30V) with a built-in transformer (in the handle), an ergonomically shaped handle, and light weight (0.44 lbs), this Japanese tool can clean the surface off parts before a coating or paiting process and prevent static electricity when handling and assemblying electronic components. Includes a unique built-in LED light beam for detecting dust.
