Slope-adjusted measurementID TECHNOLOGY

ID TECHNOLOGYDisplays a guide distance to how far you should hit the ball, reading the uphill and downhill slopes of a course.

Employing ID Technology that reads the uphill and downhill slopes of a course, Golf mode displays the slope adjusted distance (Horizontal distance ± Height) which is a guide distance to how far you should hit the ball. This helps you to choose the right club on an uphill/downhill course where it is often difficult to accurately judge distance.

COOLSHOT 40i viewfinder display example (for uphill):
The upper figure shows the "slope adjusted distance" while the one below indicates the "actual distance".
Slope adjusted distance (Horizontal distance ± Height)* Upward incline
For an uphill shot with an actual distance of 150 yards, the Golf mode displays the slope adjusted distance (179.8 yd.), which is the sum of the horizontal distance (146.4 yd.) and the height (33.4 yd.). You can thus select the right club for even both up and down hill shots.
Measurement display mode cycle
  • Measurement range: 7.5-590 m / 8-650 yd.
  • ID TECHNOLOGY displays the slope adjusted distance (Horizontal distance ±Height) which is a guide to how far you should hit the ball and useful when golfing on an uphill/downhill course.
  • First Target Priority mode is employed. When measuring overlapping subjects, the distance of the closest subject is displayed — useful when measuring the distance to a flagstick on a green with woods in the background.
  • Target Priority Switch System offers two measurement modes: First Target Priority mode and Distant Target Priority mode
  • Single or continuous measurement (up to 8 seconds)
  • HYPER READ enables quick and stable measurement response regardless of distance
  • Measurement result is displayed in approx. 0.5 seconds
  • High-quality 6x monocular with multilayer coating for bright, clear images
  • Large ocular for easy viewing (18mm)
  • Long eye relief design affords eyeglass wearers easy viewing
  • Rainproof — JIS/IEC protection class 4 (IPX4) equivalent (under our testing conditions)

*Note: The technology behind the Laser Rangefinder with inclinometer originated from technology incorporated in Nikon’s Total Station DTM-1 surveying instrument. The Total Station DTM-1, first sold in 1985, was the first highly advanced electronic model of those surveying instruments that incorporated a distance and angle measuring capability developed by Nikon Corporation.
