My first impression on seeing this call, was that it was designed to catch hunters, not deer.
However, the guy at the booth started using it, and doing a demo for another group.
It does make excellent deer sounds.
Unlike a lot of other calls, if you blow hard on it, it doesn't quit or sound weird, it just makes a louder call.
The ones I could take pics of were blister packed, so I just scanned the brochure.
