RE: coyote calling
both the cotton tail and locator tapes will work but the locator should be used for just what the name says "a locator" locate the pack with a locator tape then work them in with somthing else.there are alot of tapes that will work,bird distress this would include such birds as woodpecker and pheasant.rodent,pig,puppy,kitten,fawn deer distress also work.but don't rely souly on that elec caller,hand calls are more effective when used properly,and besides its more satisfying when one is harvested with a hand call.after all,you made the sound not some tape or cd.
