The AFTCO GBR Harness was designed in conjunction with I.G.F.A. Hall of Fame Captain Peter B. Wright and tested on giant black marlin on the Great Barrier Reef in Australia. The GBR Harness is the ultimate tool for applying maximum amounts of drag pressure when fighting giant game fish from the fighting chair. The GBR is designed to be used with the “stiff-legged” technique using 80lb- Unlimited tackle in fighting chairs with seat widths over 20 inches wide.
