"A short barrel take on RNT's proven DC Mondo sound, the RNT Calls Mondo S Duck Call gives duck hunters the southern Mondo sound they like with a little higher pitch. Hearkening back to the days duck hunters would simply saw off a section of a call's barrel to get the sound they were looking for, the Mondo S shortens the standard Mondo barrel a full 3/4"". This shorter length speeds the air going to the reed and reduces backpressure to add a higher pitch to the Mondo's trademark rattle through the middle while maintaining its clean top. Durable acrylic construction for consistent pitch and sound hunt after hunt. Short barrel version of the proven DC Mondo duck call Full 3/4"" shorter barrel - speeds the air going to the reed, reduces backpressure Adds a higher pitch to the Mondo's rattle through the middle Same clean top on calls Acrylic construction - durable and consistent"
