The all new Mannysub 8.5mm custom spear shafts are superbly finished. The attention to detail needs to be seen to be believed.

These are among the few shafts in the market that are factory certified for straightness.

A perfectly straight shaft will greatly improve the accuracy of the speargun.

A new feature to this shaft is a welded D bridge. This provides an alternative option 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. When fighting big fish generally the main wear and tear area on shooting lines is where it connects on the spear shaft due to sharp edges and burs. This new option will greatly reduce wear and as a result reduce the loss of the shaft and a trophy fish.

Welded shark fins deliver ultimate 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, giving an extra 5 cm of rubber stretch.

This system yields 5 cm extra stretch for the main rubber and 15 cm extra for the second rubber, a total of 20 cm extra rubber stretch when using a double-rubber gun. This significantly increases the velocity and range of the speargun.

The back shark fin comes with a pre-drilled hole as an alternative place for connecting the shooting line. This option makes it suitable for all spearguns with enclosed tracks.

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 wishbones can be overlapped on top of one another on the same shark fin, the other two wish bones will fit just in front of it on the other 2  shark fins  making suitable for a 4 rubber speargun .

This unique layout of the shark fins makes it suitable for conventional multi band spearguns as well as roller spearguns, while at the same time helping to depower the roller system when shooting smaller fish near the bottom if required. This increases the versatility of the spear gun.

The hardened stainless steel used in the manufacture of these spears has excellent corrosion resistance – the shafts do not rust.

These shafts will suit all European/South African handles
