The speargun in this video is sold here:
Here is a 10lb Bass shot by Titus Bradley of Portland Bill in Dorset with a Rob Allen 110 carbon set up to maz power and range with the double 16mm rubbers and a double wrapped line. As far as I am aware, Crystal Vis are the only UK company that sells these max power rigs as standard.
Rob Allen guns are like the chuck Norris of spearguns.
