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.

My brother uses the Keller and swears by them. It is very well built. If I ever decided to try one that' d be the way I' d go. Though to be honest, changing sites 1 week before a hunt isn' t a good idea in my opinion. I' d practice with what you already have and save any changes for after the season.
