Hi, i'm a total novice at spearfishing. recently bought a Seac Sub Crossbow 80 railgun on ebay. Doe's anyone know anything about these guns or if anyone stocks them or assesories for them in the UK. I am unable to work out how to attach a line to this model. There is an attachment point at the front of the gun to tie a line to. And there is some sort of clip in the base of the handle. But for the life of me, I cannot understand how the line would be retained by it or see any other means of storing loose line. Any ideas?
