Don't make blood trailing any harder than it has to be. With the Trophy Ridge Meat Seeker, you get ultimate penetrations that result in massive entry and exit wounds. These blades are deployed without levers or cams that can fail due to loss of energy. The "piston-hammer" technology guarantees rear blade deployment every time. While some broadheads hang up in bone, the rotating head finds the path of least resistance around bone for maximum penetration, tissue damage and blood loss. Tough doesn't even begin to describe these solid stainless steel blades since the tip, shaft, insert and blades have all been heat-treated for maximum durability. The three .039" thick blades combine to create a lethal 1-1?2" cutting diameter. The blades have no barbs to catch in targets, so arrow removal is easy. Sighting in is simple because these blades have field-point accuracy and won't change the flight path of your arrow because of the streamlined .55" flight diameter. 100 grain only.
