The ocean is a diverse and complex environment where the spearfishmen operates in a completely alien environment. As the spearfisherman gazes down on a boiling ball of sharks attacking a wounded fish, a majestic Marlin feeding, a shoal of tuna gliding through the depths, or a school of circling dolphins, the diver immediately understands that he is witnessing mother nature as close as is possible. And shortly thereafter should realize that the sea is big, and that he is small.

Big surf and strong currents present several potential hazards to divers:

• Avoid launching craft and always ensure that you have a clearly visible diving float that makes others aware of your position.
• Avoid shorediving when the surf is big. Chances are that it will get even bigger while diving, making the dive to the shore that much more challenging particularly now that you are tired, possibly towing fish, and potentially having to come in at a location you would prefer not to.
• When shorediving, select a point of entry that is sheltered from incoming waves such as a protected bay. Remember this may not be the point you get out at.
• Memorize the topography of the coastline and plan your dive beforehand. Such that you have a variety of accessible exit points. Be aware that currents may wash you in either direction of your point of entry, plan for suitable points of exits in both directions, and remember that the surf could build quickly, and that you may have to beach in rougher surf than you swum out into.
• Never try to fight a rip current. In most cases, rip currents are relatively narrow. Rather swim at an angle with the current, parallel to the beach, and you should swim out of it in this way.
• When diving from an anchored craft, always swim against the current, so your return will be possible when you are exhausted.
• Most importantly never panic. Stay cool. Stay calm, and ensure that you stay together with your diving partner.
