The world's most versatile peep now is available with a hood that cuts glare from direct sunlight outdoors, and from those dreaded florescent lights indoors. When you see better, you shoot better. The 45 degree "Hooded Super Ball Peep" with crowned slots opening is 3-16" and is designed to accept all of the Super Peep 1/8" apertures, clarifiers, and 1/8" verifiers. Use of the dual aperture wrench is recommended for insertion of optional apertures, verifiers to sharpen pins, and clarifiers to sharpen target face. The 45 degree peep is generally used on bows 40" and longer. CAUTION: High powered bows create a great amount of vibration. This may loosen verifiers, clarifiers and apertures over time. Tighten your apertures before each use. If you hear a buzzing sound, this indicates a loose aperture. You may use a drop of the blue Loctite or Vibra-Tite VC 3 to help hold the apertures in place.
