Contrary to popular opinion, the only accessories you actually "need" are an arrow rest and a nockset. Everything, and I do mean EVERYTHING, else is optional.

When it comes to silencers and stabilizers, a lot depends on the bow itself. If it's got a lot of string twang, then you'll need silencers. If the bow doesn't balance properly, you'll need a stabilizer. A bow case is not an absolute requirement, but it's a wise investment. A bow quiver is also a good consideration.

Sights and releases? This is where things start getting sticky.

In the beginning, maybe it's best you do start out with everything. But once you get to the point where you've gotten your form pretty much down and you're shooting good, start experimenting. Try shooting without using the sights. Try shooting with your fingers. The only thing about fingers vs release is a different type of rest is required for fingers shooting, one with a strike plate or cushion button for the lateral paradox, vs the vertical paradox you get with release shooting.

Maybe you'll find you shoot well with your fingers but you'd be better off with sights. Or you could find you don't need sights but do need the release. Or you might actually need both, sights and release. At least you'll KNOW what you need and what you don't need.

Don't be afraid to experiment. Even more, don't be afraid to follow your own path. To me, just because everyone else is doing something, that's just one great reason for me to go and do something else.

I've been there with the sights and releases but now I'm back to shooting my compound with fingers and without sights like I did 25 years ago. I also shoot recurves and longbows. I dabble a bit in making and shooting selfbows, like I did when I was a kid in the 50's. Archery is a diverse sport. Don't let yourself get locked into only one narrow aspect of it.
