The "Next Level" series of calls from BSCC is the latest product to come from the creative mind of Big Sean. These calls are changing the game once again with all NEW Technology and Industry changing materials not used by any competitors. Each call is "Hand Casted" from a durable Urethane Rubber for durability and a lifelike sound. These calls are guaranteed not to break, crack, or fall apart in the most extreme waterfowl hunting conditions! Also, this line up offers our NEW Bourbon "FLEX" Gut, that is made from our Exclusive soft polymer plastic material for the most lifelike goose sound possible. (See details on FLEX Gut over on "Guts/Reeds" tab) Colors may slightly vary from each call, because these are not mass produced, and all made one at time in house. Made 100% in the USA, all from Big Sean himself! Warning!; never leave calls in direct sunlight and/or in a hot vehicle or container. Always keep at room temperature or cooler. Sunlight may cause dye in material to change shades of color.
