One is Masonite surface the other is "crystal" = glass, and I think that the strykers are different too...I have the masonite one and love it the only thing I think would be an issue is that when your staked out pre-dawn and the dew hits the masonite call might be effected but thats about it for now. I belive the crystal call would produce a louder call than the masonite but not for sure...
