Included in Harold Knight"s Triple Crown Series Set: 5-P Diaphragm (built with a custom blended .005 red latex reed over a thin .025 prophylactic reed, this call produces great loud raspy hen talk), 4-P Diaphragm (with same style cut as the 5-P, this call produces medium raspy turkey talk but can be used to create that ever-important soft talk that’s needed to bring them in close), and the 4-M Diaphragm (triple reed call with moon-cut bottom reed and combo-cut top reed. This call will do it all, but is great call for locating with load cutting sounds. This call is medium raspy and built with new precision equipment and new state of the art blended materials).
