For 22 years I called with a cassette caller that was pretty loud and it was on full volume all the time and it worked pretty good.
Now that I have Foxpro callers with an external speaker running off of a 12 volt battery I don't have my e-callers on full volume as much because I have a remote to control the volume.
If you are calling with any wind or breeze in terrain that is not flat and there is any brush or trees around all of the coyotes out there are not in a perfect spot to hear your e-caller.
After calling for 6 to 8 minutes on half to 3/4 volume I will hit full volume 40 with my Foxpro callers for about a minute and then lower the volume back down again. Quite often I will have a coyote show up within 1 to 4 minutes after hitting full volume.
I always play the coyote sounds on full volume 40.
Not all sounds are the same when it comes to their volume. Two of Foxpro's most popular sounds are Lightning Jack and Lucky Bird and these two sounds are two of the loudest Foxpro sounds there are. So some sounds are much louder at half volume than other sounds at half volume.
Try playing Coyote Pup Distress 3 on FULL VOLUME for 4 minutes straight at the end of your stands. When a coyote is getting it's leg ripped off they scream as loud as they can, they dont't scream at half volume.
