FIELD: physics.
SUBSTANCE: invention concerns technical means of active non-lethal counteraction to penetration to guarded objects based in water basins. The method of water-based object protection involves effect of different electric potentials on a trespasser appearing between electric current lines of different density, created in a water space, resulting in electric flow through the body of trespasser, impeding further movement.
EFFECT: blocking of submarine trespasser in guarded water space.
