Running the foxpro at low volume while using a hand caller is very effective. The open reed hand caller are loud so i can also very the sound pitches. I only use hand caller to get animals attention from 500 yards plus and short yards 200 yards or less. I used two types of hand callers. Long range and Short range open reed callers. Long range open reed is Sceery and Critter calls. Short range is all the tweety open reeds. The squeaker/coaxer sounds in the Foxpro unit is constant and a constant sound is what sucks the predador in. Once i see eyes by using the hand caller I STOP CALLING with it. Let the small coaxer due the job. The Foxpro coaxer must be lowered in volume as animal is comming closer. (You will kill more animal with a mild sound coaxer than you will a loud blast.) You need to be careful on correct volume here. This has been very effective for me in Texas, Wyoming and here in Pa. Hope this helps. Earl Fairman
