Why don't you buy them?

Our local sporting goods stores all carry them and they are listed in most catalogs like Cabela's and Midsouth Shooters as well as several web sites like allpredatorcalls.com.

I purchased several hand calls today and they were very helpful.

Pick up one tape and start hunting! They are not that expensive.
