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.
The 115g pouch contains a combination of two active ingredients, nigrosin and copper acetate, to provide a multi-sensory defence against sharks.
Nigrosin is a potent mixture of synthetic black dyes, usually used in varnish and marker pens, that thickly clouds the water, disorientating sharks.
Copper acetate replicates the chemical compounds produced by the decomposing bodies of dead sharks and is proven to act as an instinctive shark repellent.
The shark repellent powder is contained within a linen sack inside the foil pouch to allow for regulated dispersal. The linen sack has an attachment cord so it can be kept close to your body.
No marine survival kit is complete without a packet of this shark repellent.
