Some embodiments may be of spearfishing apparatus fitted with at least one magnet configured to repel sharks away from the spearfishing apparatus. The spearfishing apparatus may be one or more of: a spearfishing shaft, a spearfishing tip, and/or a spearfishing gun. Such magnets may be electromagnets powered by batteries in some embodiments.

A swimming garment formed from a stretchable elasticated fabric, wherein the garment comprises at least one sensitivity zone in which the fabric thickness is less than the fabric thickness of the region of the garment surrounding the sensitivity zone. The sensitivity zones can give a heightened sensation in a specific position of the body, for example in the abdominals. The thinner fabric zone increases the sensation of water flow/temperature which in-turn leads to a proprioceptive response to activate the muscle group beneath the zone.

An anti-drowning apparatus configured to inflate a balloon when a swimmer with the apparatus is submerged to an unsafe depth so as to help the swimmer return to the surface. The apparatus may be integrated into a swimming garment. An integrated emergency flotation apparatus may also include a manual pump configured to inflate a compression port used to store compressed air for inflating the balloon.

A cold weather survival suit includes a principal body cavity having pneumatically connected extensions to fit body extremities and a coverable cranial opening. The structure of the suit includes a layered structure of mechanically interconnected suits within suits. A composite of tear-proof and insulation material forms an internal suit or first envelope that is surrounded by a waterproof suit and then by a tear resistant suit.
