RE: duck calls
My personal favorite duck call for under $100.00, and for any priced call as a matter of fact, is the RNT Original wood. Mine is the cocobolo wood style. I like wood calls better because they tend to be softer and sound more natural, but it does have its cons.This call, like all other wood calls,tends to hang up and swell on cold, wet days after calling for a while. You can also check out the daisy cutter and the microhen. Just go to rich-n-tone.com and you can listen to the calls and their abilities.
If you are looking for a good single reed on a lower budget, check out the duck commander calls.
