The patented built-in concealment technology of HECS StealthScreen is designed to enhance your dive experience. The material is woven with HECS’ conductive carbon fibers that trap and mask your naturally-occurring electric signal output that many marine animals can detect and react to, enhancing your ability to get closer to marine life underwater.<br><br>Sharkskin Covert works by combining 3 scientific principles:<br>1. All living things emit a faint electric signal.<br>2. Some marine species can detect faint electric signals.<br>3. A conductive screen operating as a ‘Faraday’ shield can block electric signals.
