The LG Sub 8mm threaded spear shafts are beautifully finished. One of the awesome features on this shaft is the welded D bridge, which provides an ideal location to connect the shooting line. Thanks to the rounded shape of the wire bridge, shooting lines like dyneema or monofilament will not break as easily, and therefore last much longer. Welded shark fins deliver the ultimate in strength to the shaft. Unlike traditional cut out notches, they don’t cause a weak spot. This makes the shaft less likely to break and bend at the notches when fighting big fish. The back shark fin is welded further back than conventional shafts. This system provides 5cm of extra stretch for the main rubber and 15cm of extra stretch for the second rubber, a total of 20cm of extra rubber stretch when using a double rubber gun. This significantly increases the velocity and range of the speargun. The first shark fin is located in the middle of the shaft, 65 cm from the back. The second shark fin is positioned in the middle between the first and last shark fin. The 5 mini shark fins make loading a lot easier. Three of these shark fins are near each other, making this layout also suitable for 3 or 4 rubber conventional multi band spearguns. Thanks to the position of the last shark fin, two bridals can be overlapped on top of one another on the same shark fin, the other two bridals will fit just in front of it on the other 2 shark fins. You can easily power down the roller system when shooting smaller fish near the bottom if required. This dramatically increases the versatility of the speargun. The hardened stainless steel used to manufacture these spears has excellent corrosion resistance. These shafts do not rust and are suitable for all European/South African handles.
