3D shooting is fun. First thing that you need to do, if you already haven't done this, is get you bow tuned! Go to a archery shop and have them tune the bow and watch you shoot. After you have the basic down, like bow draw, sighting and release down pat or comfortable, then find an archery range and practice shooting at different yardage. If the range doesn't have 3D targets find an archery club that has 3D targets. Most clubs do not let use use any distance/ yard range finders so practice shooting by judgement or guesstimating those distances. The yardages will be different for each target. You will loose arrows and make terrible shots, but that is part of the game. If you are lucky like I am and have a big yard or field then you can practice at home. After years of shooting rifles, I found that archery is way more fun and not everyone will shoot like Robin Hood and it is more challenging than a rifle because even the smallest error can cause you to miss your target. Have fun.
