All JBL spearguns feature barrels made from either wood or aircraft grade aluminum. Both material offers certain advantages that are beneficial in the sport of spearfishing. Wood spearguns, like those by JBL, are constructed of solid mahogany or laminated teak. Their natural composition, unique grain pattern, and lacquered finish are typically considered more appealing than that of aluminum spearguns. In addition to looks, wood spearguns allow for more elaborate shapes and weighting options. These spearguns can be built to handle the energy of a four, five, or six band power source. This is because wood is solid, does not have size constraints, and can be processed in any fashion. These large spearguns, along with the help of the M8 trigger system are the “go to gun” for large pelagic hunting. All wood JBL spearguns feature the M8 trigger system. Another advantage is that all wood spearguns will float when the shaft is not loaded. While wood is great for large “tuna style” spearguns, they can be less maneuverable under water due to their mass. Aluminum spearguns like the JBL Reaper and Explorer series spearguns are built from aircraft grade aluminum. They offer a lower profile for quick movement and easy tracking properties. These spearguns are great for many different diving environments such as inshore spearfishing. Larger models are also great for blue water hunting where extended shots are necessary. At the end of the day both wood and aluminum spearguns are designed to do the same thing: put dinner on the table. Both styles are very utilitarian and can be used in very diverse diving conditions. Which model and style really boils down to individual shooting style, personal preference, and type of fish that is being hunted.
