I don't know what you mean by a "fixed pin" sight but you will have to move the pin or pins to sight the bow in for the range or ranges you are going to shoot, the sights don't come set for specific ranges so you will have to shoot at the various ranges and move the sight until the bow is shooting where you want it to shoot, since you say you will only be shooting out to 40 yards you will need a pin set for that distance and a couple of closer distances. Your best bet is to go to an archery shop and look at the different pin sets they have available. One more thing, if you are hunting from a stand, sight the bow in from the stand, you can get it close on the ground but fine tune it from the stand.
