yo everybody, i am aspiring surfer and i surf in south africa, in Very sharky beaches. and i would buy a shark shield, but its waaaaaaaaaay too expnsive, and i know there is small chance of me getting attacked but i have lost my friend to Tiger sharks at Port St. Johns second beach. and i dont wanto get attacked. so what must i do as a protection method from these animals. do a ritual or ask my GD or what ?
