Never shot a predator, I used a keller for years and always hit what I was aiming at from a tree stand, Ground shooting is a little tougher. Also it was a bit noisy thats why I switched to a savage QC Ranger with a tritium pin. http://www.savagearchery.com/ I would go with this sight and avoid having to buy another at a latter date. It is also Ideal for shooting on the ground , just click in the yardage your shooting at and its right there no need for all kinds of pins.
