Here is a link to Idaho fish and game. You can get all the regs there.
I live near Orofino at the head of Dwarshak lake. I hunt both sides of the lake in 8A and 10A. We have elk, deer, black bear, cougar and the turkeys.
The elk are harder to hunt due to lower populations in the last few years. Most of us blame the introduction of wolves, but there are other problems causing this also such as not letting the forest fires burn causing low brouse growth.
I think the wolves don't let the elk heard up like they used to do and keep them seperated and moving more. Makes it hard for old crippled hunters like me to chase them.
I spent a lot of years handgun hunting in this country and suggest the use of a good big bore. I used a 44 magnum with good results.
You cannot use any electronic sights, i.e. red dot scopes or sights. Scopes and open sights are ok as long as they do not use an illumnated reticle or a battery.
Turkey hunting is limited to shotguns, I'm not sure about archery, but you can look at the regs at the sight I gave you.
