What You Hoping to Use it For?
Aloha Big Island,
You goin' to try to call sheep and goats to you? Sounds like fun.
You should be able to mimic them with your voice reasonably well. I guess the trick will be to find the pitch that works.
You're probably familiar with the way the rifle hunters do it? Wound a goat and let it bleat until other goats show up... not exactly humane, but "this ain't Hollywood."
My buddy was stalking a mouflon on Lanai a few years ago and shot over its back. I "baaed" at the 3/4 curl ram and it froze staring at me. I held its attention while my buddy slung three more arrows at it before finally hitting it. Steep downhill angle made it a tough shot--not to mention the mounting tension!
If you have luck with your calling, let us know!
