Compatible with add-ons like a reel and roller muzzle, this speargun grows with you, supporting your skills at every level.

ARCHAIC, BRUTAL, and SAVAGE words perfectly define both the Jurassic Period and the HammerHead Jurassic™ speargun. Clean – simple lines are unleashed with a South African-inspired Jurassic™ open muzzle and Oxide Steel Shaft.

＊＊＊Originally, this model features a closed muzzle; however, our store specially offers an open muzzle model tailored to the preferences of local customers. Although this model does not appear in the video below, We have including it because it is very similar to the E2. The differences from the E2 include having a single rubber band instead of two, and the shaft is not Sharkfin type but rather Notched Type.
