i have been bow hunting about 3 to 4 years, with an old bow. and i thought that i had it all down pack. i started making some bad shot and not able to find my deer. so i deside not to shoot at any thing until i bought a new bow and set it to my specks. now i have that new one and can not wait to go hunting with it. my advice to you is what i learnd, perfect practise makes perfect shots . howard, good luck. remember, once you send your arrow to a animal, there is stopping it.
