The patented SealRite™ cushioned frame technology conforms to virtually every palate size and shape. SealRite™ increases the call vibration zone between your tongue and palate, bringing the reeds closer to your tongue for ease of use. The design eliminates the tab to tongue contact point, resulting in a clean operation platform. The result, a superior sealing call that is easier to achieve unmatched realistic turkey killing sounds. The SR Cutthroat™ is meticulously crafted of three and a half .003 latex reeds. The backer reed adds stability to the triple cut longest reed which adds realistic rasp; the SR Cutthroat™ performs the heavy rasp vocalizations of the wild turkey, with added stability for loud aggressive calling. The SR O.B.H.™ is meticulously crafted of two .006 latex reeds. We slit the corners on the longest reed which adds realistic rasp; the SR O.B.H.™ is the easiest call to perform the medium rasp vocalizations of the wild turkey. The SR Double™ is meticulously crafted of two .004 latex reeds. The easiest call to operate, the SR Double™ is capable of performing the clean clear vocalizations of the wild turkey.
