from what I just read it seems like they need to have a masters in Hunter. I dont think most operators of these things will be as knowledgable at using them as they need to be so that leads to the next problem lol. I'm just one of them people that just cant get a proper job done on my car. Went to discount 17 times now and to this date they didnt use that thing to calm me down yet....retards. Now that I read all thet maybe I can show them how it works?
