The "Dualie" Fox whistle
Variable tone fox caller made from strong high temperature plastic.
Has a tooth grip on each side for hands free calling on both sides and a raspy tone rather than the high high pitched version of the fox whistles that we find works very well.
Each side emits a slightly different tone that can be varied by pressure once you have mastered the required technique.
Made from a strong high temperature plastic that won't deform if left in you car like others available.
