Frequently Asked Questions
What diameter options does the Seac Shark Laser shaft come in?
Seac's manufacturer catalog lists this shaft in two diameters, 6.5 mm and 7.0 mm. Check your pneumatic speargun's original shaft or muzzle specification to confirm which diameter your gun requires before ordering, since using the wrong diameter can affect loading and fit.
How do I pick the right length for this replacement shaft?
This shaft is available in seven lengths, 41.3 in, 45.3 in, 47.2 in, 51.2 in, 55.1 in, 59.1 in, and 65.0 in. Match the length to your pneumatic speargun's barrel length, or replace an existing shaft with the same length to keep your gun's loading and handling consistent.
What makes the Shark Laser shaft's construction different from a standard shaft?
It is made from heat-treated 17-4 PH stainless steel, uses Seac's Shark-style profile, and has laser-welded fins. Its fins are laser-welded to the shaft, as specified by Seac.
