This is the single reed call that doesn't leave the lanyard. From vast open water setups to tight forested sloughs, the 737 "No. 1" duck call is a do-it-all, get-it-done call. With lots of range, it has the ability to get super loud for those high ringing hails, but still has a raspy bottom-end all the way down to those ultra soft confidence quacks.
