I'm thinking about replacing the factory supplied scope that came with my TenPoint Titan Extreme with a Hawke crossbow scope for deer hunting. I don't expect I would ever shoot beyond 40 yards or so since the stated speed is in the range of 315 - 330 fps. It seems like the fixed 3x would be all I need, but are there tangible benefits to have a variable like a 1.5-5x? I am ambivalent about having an illuminated reticle because I can just leave it off if it doesn't seem to help.
