There are a host of resources on the use of e-collars. I've used them for over 20 years with success and no one I know runs a dog in the field without one.
How you use the collar is to enforce a command you've given and which the dog knows and heard, and ignored. I use tone on my collars almost exclusively, rarely nick them, and almost never have to burn them. They know what the tone means.
Not sure what you mean by "constantly." I use two toots in rapid succession from my mouth, the same cadence as the two toots from the tone on the collar, both to mean "pay attention and come around." Come around means turn back toward me. Others do things differently I'm sure. Dogs and hunters are all different so use what works for you.
