Pat, It is a delicate balance hunting yotes,the early season young can be duped fairly easy.Late season yotes are entirely different,They are very wary and will all most always swing down wind before commiting.I have chased them for close to 25 yrs.They still make a fool out of me at times.Thier intellegence is not to be under rated.Set up is everything,I try to position in such a manner that they have to expose themselves enroute,while taking the wind into consideration.Thier nose is second to none,as well as thier eyes! Electronic calls have a place in yote hunting, but that place is not in tight quarters.IMO the the electronic callers is great for windy days and wide open areas, to start them in towards you.Then switch to a mouth call or final coaxer to seal the deal! It has been my experience that you can blow a set up quicker than anything by over calling!!!!!!!!!!!I would suggest a electronic caller with a 200 yd remote,they can work extremely well if you set up properly!I do most of my calling with mouth calls.They are extremely effective as you can vary the intensity.You can put so much emotion into the mouth calls! Matching the camo to the terrain is very important.They do not miss anything! I would master the howler as a locater,and master the mouth calls, and use the electronic callers as the situations dictate.Yotes learn quickly, try not to educate them!Practice at your buddies place!!
