For a newbie, I recommend hand calls, but not for the reasons most guys might (tradition, heritage, enhanced skill, blah...)
Here's something real - you're new to calling coyotes, so you ARE going to alert a lot of coyotes when you travel in the field. Yes, it's an advantage for a hunter to be able to place his caller away from their shooting location to keep the coyotes attention elsewhere. But - that only works if you don't let every coyote in the county see and hear you while you are placing your call then finding your shooting position. Once a hunter has a grasp on how to travel in and out without blowing every hunt, an electronic caller can be an advantage, especially for the solo hunter.
Having a good set of hand calls is a good idea, and a low cost investment. Someday, you WILL be in the field and your batteries will die or you'll misjudge your remote range or some other problem will befall your electronic caller. Having about $100 worth of hand calls around your neck when that happens will keep you in the hunt, instead of leaving you with no option but to pack up and head home.
