A big advantage a e-caller has over hand calls is being able to put out sounds for the whole time you are on a calling stand.
When you are calling and stop playing a sound on a e-caller or stop to catch your breath with a hand call, if nothing has heard your sounds you are no longer calling you are just sitting there taking a break.
In the open country we call coyotes in, the louder volume of a e-caller will get your sounds out to more coyotes than lower volume will. Many times we have had coyotes run right up to our e-callers while they are on full blast volume or they show up 3 to 6 minutes after going to a louder sound or a loud sound on full volume.
Many times after calling continuously for 10 to 15 minutes on very loud volume I have had hard charging coyotes show up. When this happens I am pretty sure that the coyotes just heard my calling sounds and that is why they just showed up.
If they started running that hard when I started the loud sound, they could travel 4 miles in 15 minutes. Coyotes are not always in a spot where they can hear the sound you are blowing or playing on a e-call. If the coyotes move or are changing locations while you are not blowing your hand call or not playing your e-caller the coyotes won't be able to hear any sounds because there are no sounds being put out.
Just a slight wind change or coyotes changing locations can get the coyotes to hear your sounds, if you are putting the sounds out there.
