The PROTIR barb was designed and engineered to minimize fish loss and extend the lifespan of spearfishing shafts.
Similar to a detachable point (slip-tip), the fish is pierced by the line, not the shaft. Therefore, it cannot leverage against it to free itself. Only the barb detaches.
​
Once the fish is in hand, the shaft is easily removed. Simply reverse the barb (see video).
​
The PROTIR system is installed in place of the original barb. Unlike detachable points which require a specially dedicated threaded shaft, the PROTIR fits on any standard shaft. Note that a minimum distance of 11.5 cm between the barb axis and the speargun head is required. See FAQ for details.
​
There is a kit for each shaft diameter: 6.5 - 7 - 7.5 and 8 mm. Choice of Dyneema 400 kg braided line or stainless steel cable with sleeves (for coral environments).
Its advantages (compared to slip tips):
-
Prevents frequent play between the two parts of the slip tip.
-
Prevents the shaft from twisting during heavy strikes.
-
Stays securely in place thanks to the O-ring. (unlike slip-tips which can detach inadvertently).
-
Reduced costs. It does not require the purchase of the "threaded shaft + detachable point" set, which is usually very expensive.
