Your accuracy depends on the quality of your spearshaft. Each JBL Spearshaft is meticulously hand-tuned for straightness in our Oceanside facility. After being heated to over 900 degrees Fahrenheit and allowed to cool slowly, these shafts offer unmatched durability and precision.

If you’re unsure which spearshaft fits your speargun, refer to our Specs Sheet for the right size and compatibility.
