Rob Allen Tuna Railgun

See all pictures

South African manufacturer Rob Allen is renowned for producing some of the most deadly and accurate spearguns on the market. Its Tuna Railgun has been tested on the largest pelagics that are found in the southern hemisphere.

The only downside is the railgun design that produces all the power as it’s noisier than the majority of band-powered spearguns. So you need to make sure your shot finds its target. However, it’s such a versatile gun that can be used in both shallow and deep water, that it’s a great investment for beginners too.
