The open ocean offers little mercy to those who venture out beyond the sight of land. Underneath the surface holds yet another unforgiving realm where predators constantly compete for food and territory. Enter the spearfisherman… out of place in the underwater foodchain, these divers turn the tide on what was once the hunter. Weilding heavy band-powered spearguns, this crew foregoes the bulky scuba tanks and dives head first into the depths after World Record fish. Follow Sasa Bratic, Chris Gardinal, Gary Sanchez, G.R.Tarr and Sheri Daye down to Costa Rica where both Chris and Sheri set World Record Shooting Yellowfin Tuna! Out in the Gulf of Mexico off Tampa Bay, Florida. The team pursues monster Amberjack and elusive Gag Grouper and Snapper. Other locations include the waters off the coast of Oahu, Hi; Cape Hatteras, NC; and the Oil Platforms off Mississippi and Louisiana.
