Hi Terry,
Shooting IBO off season will definitely better your skills. Our tournaments are set as close to hunting situations as any archery tournament you will find. Bowhunter and their clubs are who founded and started the IBO. So you are in the right company! Welcome!
Ok, on to your questions:
1. For either local or National levels, there are entry fees and those depend on what class you are shooting in.
2. Your class is determined by your equipment. Go to our www.ibo.net site all our rules and classes are there under "Rules".
3. At the National level shoots the shoots are three days long and again depending on your class is how it is determined the number of days you shoot. Since you a new I would assume you would be in a amatuer class so you could shoot all 40 targets in one day or split up your 40 into two days.
4. At an IBO World Qualifier, we let the host club decide if it would be a one or two day event and also the cost to shoot. The top 20 scores in each class qualify to go to the IBO World Championship.
5. At the National level you will always shoot 40 targets. At a World Qualifier the host club has the choice of either having 30 or 40 targets.

Hope this helps. As an IBO member you will receive the 2005 IBO Yearbook which has ads about all IBO National Level events as well as lists of World Qualifiers.
