As I am new to bowhunting, I am assembling my new bow currently and do not have a sight. I was thinking of getting a sight that was good for the bush, could see in low light and that I could sight in up to 70 yards.

Do I need a microadjust or something specific for this kind of setup?

I use a Sword 3rd Axxis sight. Cant say anything but good things about it. The pins are bright (it comes with a pin light too), and it has stood up to quite a bit of abuse during my hunting endeavors.
Oh yeah, it came with 6 pins, but I took one out because it seemed a little too cluttered.
