ProStaff 550

Budget-conscious hunters can get the same 550-yard ranging capability and waterproof/fogproof integrity as with the RifleHunter, but without the ID technology feature.

• True 550 yard ranging capability: For virtually any hunting situation.
  
• Tru-Target™ ranging system: Flexible ranging mode capabilities for various hunting conditions and terrain.
  
• Easy-to-view uncluttered LCD display: For fast, easy ranging, even in bright sunlight.
  
• Bright, multicoated 6x optics: Nikon’s legendary optics and proprietary anti-reflective coatings offer high-resolution images in most lighting conditions.
  
• Single button operation: For fast, easy measurements. Automatically powers down after 8 seconds to reduce battery use.
  
• Ultra-compact Size: Fits in a pocket or pack, and can be worn on a belt without interfering with your shot.
