Bison Trawl Doors

Efficient and Versatile

The Bison door is individually designed to suit your fishing requirements.  They take your needs and split it two ways to produce an efficient shape for fuel economy, and to produce a door of a certain weight, size and balance to provide the best catching potential.

Why are Bison doors so different?

They specialize in manufacturing trawl doors, and are continually carrying out research, working on board trawlers of different nations, and keeping in close contact with Skippers/Captains.

The believe trawl doors have to be individually designed for different areas and type of work.  The fishing results of the Bison door have proved this beyond doubt.

The underwater video filming has been invaluable in their research, and proves that the Bison door is so steady and stable on the bottom, even on the roughest ground, or peaks, with excellent ground contact, and yet the door is good on mud as hard ground, and can be used in shallow water to very deep.
