Copper acetate replicates the chemical compounds produced by the decomposing bodies of dead sharks and is proven to act as an instinctive shark repellent.
This shark repellent is NATO approved, is used by naval and airborne armed forces across the world and is a must have for any marine survival kit.
Nigrosin is a potent mixture of synthetic black dyes, usually used in varnish and marker pens, that thickly clouds the water, disorientating sharks.
The 115g pouch contains a combination of two active ingredients, nigrosin and copper acetate, to provide a multi-sensory defence against sharks.
