Nikon Introduces New Laser Rangefinder "Laser 550A S"

March 1, 2008

Nikon Vision Co., Ltd., a subsidiary of Nikon Corporation, is pleased to present the Laser 550A S, a laser rangefinder with angle compensation technology. With its external LCD display, this laser rangefinder instantly provides actual distance, angle, horizontal distance, height, and vertical separation (difference in height between two targets).

Since Nikon released its first Laser Rangefinders in 1999, they have been well accepted by wide variety of users, from golfers to hunters. Our new Laser 550A S has been engineered to comply with their request for angle compensated distance measurement. With its built-in inclinometer, Laser 550A S gives instant readings on the target, from actual distance to angle, height, and horizontal distance, even vertical separation between two targets. This information allows a user to take a shot with more confidence, whether in golfing or hunting.

Measurement example (in golf use):

Key Features

  • Linear (actual) distance, horizontal distance, height, angle, and vertical separation (difference in height between two targets) can be measured with easy one-push operation.
  • The results are displayed on both an internal and an external LCD panel. The external LCD panel shows all results simultaneously.
  • Select from two measurement modes (Target Priority Switch System):First Target Priority Mode for golf or Distant Target Priority Mode for hunting.
  • High-quality 6x monocular with multilayer coating for bright images
  • Waterproof (up to 1 meter for 10 minutes): Sealed with O-rings and filled with nitrogen gas. The battery chamber is water resistant.
  • High-eyepoint design allows easy viewing even with eyeglasses.
  • Capable of distancing different targets in succession, for up to 20 seconds, by keeping the button pressed.
  • Measurement range: 10-500m/11-550yd./ 33-999ft.

  • *The specifications of the product may not be achieved depending on the target object's shape, surface texture and nature, and/or weather conditions.
  • Note:The origin of the technique of this Laser Rangefinder with inclinometer is the Surveying Instruments incorporated measuring capability of both distance and angle which were developed by Nikon Corporation. Among such products, especially, the first highly advanced electronic model, the Total Station DTM-1, is the root (Sold in 1985).
