Hey in about two weeks I'm going to place to do some diving and spearing. My landlord and his wife have a beach house there for about 30 years now fish all over the place where I'm going! He told me there is a good chance I will run into sharks in 3 to 4 foot range! I've never run into sharks before and need some advice on how to handle things to keep them from showing up and once one shows up! I thought sharks this size would be to scaried to get close to a diver? am I wrong?
