About the only advantage I've had using e-calls vs hand calls is I use a remote caller that I position at an optimum spot to "bring in" the yote for optimum shots. I also use a remote "flagger" at times. There are times when location is at a premium that I have to use hand calls to get them into a visual range. Your location will dictate what you should use. If I'm in a generally "populated" area and have to use a shotgun, then I use a hand/mouth call. Usually a distressed rabbit. If I've broken out the .22/250 or the .220 swift then NORMALLY I break out the e-call. Like Nomercy said, you need to learn when and how much calling is needed. In other words, know when to shut the hell up as my dad always so politely put it. Some people mistakenly compare yote calling to turkey calling. In a FEW respects it's the same but a yote has a couple more senses that a turkey doesn't have in abundance. There are times it is so easy it's almost not fun, "ALMOST", and other times that you will see tons of yotes laughing at you from out of range.
