i had one of the old cobra's and a keller. both workrd great. could shoot pine cones all day out to just over 30 yds. never did really like them though. went back to pins. just recomend getting one you can lock in to shoot from ground level if you have to. the guys i know that still shoot the newer keller wouldn't shoot any thing else. mr keller with help if you have a problem just give him a call.
