The Competition VoloChoke is the ONLY mass produced injected molded duck call to win the World Duck Calling Contest. Now, everyone who is interested in competing in world class duck calling contests need not be held back by the usual high priced calls used by most of the top callers. For $29.95 you can compete with the same call design as the 1996 World Champion and 1997 Winchester World Open Champion. The Competition VoloChoke is a fixed volume VoloChoke of extremely high volume and pitch. It comes with only one installed choke. It is designed for the high volume demands of today’s competition, but can be an “ace in the hole” on those extremely windy days.
