Every living creatures nervous system emits an electrical voltage. Predator fish sense this voltage in the live bait and rely on it to locate and capture food. The EChip duplicates this voltage that predator fish detect. The EChip is made of a proprietary electronic crystal and ball in a stainless tube. In water, the crystals hypersensitive electrons are activated by any movement or vibration. No batteries are required and the EChip never wears out.
