Speargun shafts for band-powered and pneumatic spearguns from Rob Allen, Mares, Cressi, Salvimar and Seac: diameters 6.6, 7, 7.5 and 8 mm, in several lengths, single-notch, double-notch and Tri-Cut versions, flopper and drop-barb tips, plus tip protectors.
How to choose: the diameter and length must match your speargun, so start from the gun's barrel length and the original shaft. Thinner shafts are faster and better for smaller fish, 7.5 and 8 mm shafts for bigger fish and longer guns. Band and pneumatic shafts are not interchangeable.
