Jeff Stafford and Dusty Holloway are the entrepreneurs behind Shell Bobbers, fishing bobbers made of empty shotgun shells. The ammo shells are filled with floatable material that allows the shells or bobbers to float upright in the water. They pitched their business on Season 4 of Shark Tank and made a deal with billionaire investor Mark Cuban — $80,000 for 33 percent equity.
Shell Bobbers now sells under the name Fishing Ammo and has received celebrity endorsements from fishermen including Duck Dynasty star Willie Robertson. They have extended the line to include Shell Bobbers Keychains ($1.99).
