Did he react like this to the collar? Have you hunted him without a collar? If you haven't had him properly conditioned to use with a collar so he understands that it is a GOOD thing versus a "oops, I'm getting shocked/beeped -- dad's not happy with me!" the first time with it on. Some dogs are wrecked for life if you just take it out and put it on, and some get over having it on. I have one dog that I refuse to work with on a collar for hunting at all, he's collar wise.
Or, was this in relation to those OBNOXIOUS beepers? You are better off with a heavy-duty bell that's less of a pain to your ears and his. Many dogs, again, if not conditioned to the noise, never get over it; while some just figure it out. The best way I was explained for a beeper was to have me put on my dog's e-collar (wrist or carry it around by your head) and listen to the darn thing beep for a while. You'll figure out how much a pain in the butt it is.
The time to help with this would be to just have the dog wear it doing fun things with it on. Bumpers, chasing planted birds, letting pigeons go with the dog wearing the beeper, eventually the need to find birds will take over and the collar will be a habit.
