The Nikon COOLSHOT 50i GII rangefinder has a listed laser-ranging accuracy of ±1 yd under 100 yd; ±2 yd to 999 yd; ±0.5% at 1000+ yd. On the course, DUAL LOCKED ON QUAKE visual + vibration helps with target acquisition and the listed maximum laser range is 1200 yd.

COOLSHOT 50i GII accuracy by distance
What this means on the course
The COOLSHOT 50i GII has a distance-dependent accuracy specification. Use the band that matches the distance you are measuring.
The listed maximum laser range is 1200 yd. That is a reach specification, not a promise that every target is equally easy to acquire at that distance.
Target acquisition and aiming
DUAL LOCKED ON QUAKE visual + vibration helps confirm that the laser acquired the intended target. It improves target selection confidence, not the published numeric tolerance.
6x magnification gives useful target enlargement for aiming; optical magnification and laser accuracy remain separate specifications.
Accuracy vs repeatability vs display precision
Accuracy is closeness to the true distance within the stated tolerance.
Repeatability is how closely repeated readings agree when you aim at the same target.
Readout precision is how finely the number is displayed. Fine display increments do not automatically mean the laser is accurate to that same increment.
At 1000 yd, Nikon’s ±0.5% band equals ±5 yd; the numerical tolerance increases with distance in that band.
What can affect the reading?
Small or low-reflectivity targets are harder to isolate than large bright objects, especially when there is background clutter.
Bright sun, mist, rain and target angle can make acquisition less consistent even when the device is functioning normally.
If a number looks implausible, re-range the same target from the same position before treating it as a calibration problem.
The COOLSHOT 50i GII is listed as IPX4 / rainproof. Environmental protection does not guarantee unchanged laser performance through rain droplets or fog.
COOLSHOT 50i GII accuracy troubleshooting
DUAL LOCKED ON QUAKE visual + vibration does not confirm the flag
Sweep slowly across the flag or flagstick. Target-confirmation feedback helps identify the intended target; it is not a separate accuracy measurement.
Repeated readings differ slightly
Keep the same aim point and take several readings. Small variation inside the published tolerance can be normal; a large repeatable offset is more meaningful.
Yards and metres seem mixed up
Check the unit setting. 100 yd is about 91.4 m, so a unit mix-up creates an error far larger than normal laser tolerance.
Slope distance does not match straight-line distance
That can be normal. Compare the raw/actual laser distance when checking ranging accuracy; slope-adjusted distance intentionally changes the number.
Nikon COOLSHOT 50i GII accuracy FAQ
How does COOLSHOT 50i GII accuracy change with distance?
No. The published tolerance changes by distance: to 99 yd: ±1 yd; 100-999 yd: ±2 yd.
Which distance band has the tightest COOLSHOT 50i GII tolerance?
The tightest listed band is to 99 yd at ±1 yd. The farther published band is 100-999 yd at ±2 yd.
How far can the COOLSHOT 50i GII range under its published specification?
The listed maximum laser range is 1200 yd. That is a maximum reach figure and does not mean a flagstick will be equally easy to acquire at that distance.
What does DUAL LOCKED ON QUAKE visual + vibration do on the COOLSHOT 50i GII?
The DUAL LOCKED ON QUAKE visual + vibration feature is designed to help identify or confirm the intended target. It can make pin acquisition easier, but it does not change the laser’s stated numeric accuracy tolerance.
Does the 6x optic make the COOLSHOT 50i GII more accurate?
The 6x magnification enlarges the target to help you aim and hold on a flag or other object. It can improve practical target acquisition, but optical magnification does not alter the published laser tolerance.
