A Quick Spear Fishing Guide

Spearfishing has turned into a popular sport around the world

. It has enthusiasts from your United States to Australia, Nz, Japan, Africa, and lots of other destinations including colder climates. The action of spearfishing requires that a diver be submerged underwater, either on a breath of air (commonly called "freediving") or using scuba equipment. While underwater, the diver uses among a variety of spearing devices to capture their prey.

Some common spearfishing tools are spearguns, polespears, and Hawaiian slings. The spearguns are the same shape as a traditional "gun," but shoot a long metal shaft, usually powered by thick rubber bands (aka "band guns") or compressed air (aka "pneumatic guns"). On a speargun, there is often a tether connecting the shaft on the gun, and there are different types of devices for the end with the spearshaft that prevent the fish from coming off. Those same devices typically be found on polespears and Hawaiian slings also, the most simple as a single "flopper" that opens up once the shaft has passed through the fish.

A polespear includes a long, stiff pole (usually 5-8ft.), with a thick rubberband protruding from end as well as a short spearing device on the other end. The diver shoots the polespear by grasping the rubber band between the thumb and forefinger, stretching it on the shaft, and grasping the shaft with the exact same hand keep rubber band. If the target is within sight, the diver aims the spear and releases it, hopefully punching the fish. In some places, like aspects of the Bahamas, spearguns are illegal and divers must use devices like polespears or Hawaiian slings for shooting fish.

The Hawaiian sling is nearly a mixture of a speargun plus a polespear. It shoots a shaft similar in appearance to a speargun shaft, but it has no "trigger" mechanism. the Hawaiian sling is usually a small handle, that allows a spearshaft to secure, and there is a rubber band attached that this shaft is pulled back on. The theory is similar to that the bow and arrow work, however the mechanics vary due to the fact that it needs to work efficiently underwater. Overall, the Hawaiian sling and polespears are quite obvious devices.

The various techniques utilized to dive underwater vary from region to region. Breath-hold divers are commonly referred to as "freedivers." Freediving is a sport all alone and there are numerous competitive freedivers worldwide. Competitive freedivers compete for diving to great depths underwater using one breath of air. Freedive spearfishing is quite common in many places, and in some countries, it is the only way to spearfish legally. The greatest risk related to freediving is a phenomenon known as "shallow water blackout." Shallow water blackout occurs a diver has stayed submerged for too much time, and upon going back to the surface, themselves tissues expand (primarily the lungs) pulling oxygen in the blood. It is important for freedivers being knowledgeable about your schedule associated with shallow water blackout and also the safe practices which can help prevent it.

Scuba is also a popular means of underwater diving while spearfishing. All scuba divers breath compressed air from a tank while underwater. While scuba diving gives the benefit of allowing the diver to keep submerged longer, it has disadvantages as well. The bubbles in the escaping air that scuba divers breathe can scare fish off, and technical scuba divers must obey scuba safety requirements strictly so that you can not be vulnerable to "bends" or decompression sickness brought on by compressed gasses escaping bodily tissues. It is crucial that scuba divers go through proper training and certification before using scuba equipment.
