  • Promotes excellent sound quality for elk calling applications.
  • Includes a camo lanyard and cover for convenient carry and storage.

Considerations & Trade-offs

  • Requires a mouth call diaphragm to be used as intended, so it is not a standalone calling setup.
  • The 21 3/8" tube length may be less convenient to pack or carry than a more compact call.
  • The 1 1/2" mouth opening is a fixed design detail, so users who prefer a different feel or setup may need time to adjust.
  • Its purpose is focused on elk calling, so it is a specialized tool rather than a general-purpose game call.
