Alright this might be a newb question, but it just never made sense to me, I know you need to have a bow press or some sort of portable bow press to hold the limbs compressed a little bit to get the string off and what not, or else chuck norris, one of the two.....I have yet to meet someone who can change their compound bow string without any sort of tools, but I'm not saying it isn't possible cuz there is probably somewhere who can do it, but alright, I have seen in ads and stuff for bows that can adjust the drawlength without the need for a bow press, how the heck is that possible?...or is it just some marketing slogan thing to make it look like the bow is an easy beginners bow, I've always wondered, sorry if it is a newbie question.
