Choosing the right Rob Allen speargun spares

Rubbers and wishbones

Tuna Blue bulk rubber has a pure amber core and a UV- and abrasion-resistant blue outer layer and comes in 14, 16 and 20 mm, sold per 10 cm. Standard speargun rubber is sold per metre in 14–20 mm. Thicker rubber gives more power but is harder to load; the Rob Allen open triple muzzle, for example, recommends 14 mm rubber, or 12 mm for easier loading. As a guide, Rob Allen pairs a 45 cm rubber with a 50 cm gun and a 76 cm rubber with a 140 cm gun.

Lines and reels

Shooting and reel lines include Dyneema 2 mm in 60 and 100 m spools, 1.9 mm UHMWPE Ant line, 2 mm nylon and a nylon kit with crimps. Vecta reels weigh 95 g, mount on a dovetail bracket and fit all Rob Allen and most Euro-style guns. For floatline bungees and anchors, also see Floats, Flashers & Boards.

Vecta 2 handle parts
