Best features of the Nikon Coolshot 40 laser rangefinder

Hyper Read Technology

For faster and more accurate readings, the Nikon Coolshot 40 laser rangefinder uses Hyper Read Technology.

This technology measures distances at a fast rate and gives you results in just 0.5 seconds, regardless of the distance to the target.

The built-in calculator calculates the time it takes for the laser to reach the target and return.

It then divides the speed and gives you the distance.

First Target Priority

If you have ever ranged flagsticks against a background of trees or other objects, you know how frustrating it gets.

Sometimes the rangefinder will lock on to an object that you aren’t ranging but with this rangefinder, you don’t have to worry.

With the use of First Target Priority technology, the Nikon Coolshot 40 rangefinder gives you the distance to the closest object among all the targets.

Regardless of the hazards around, the rangefinder will range to exactly what you want and nothing else.

This ensures precision and gives the user a better chance of sinking his shot.

Continuous Measurement

The Nikon Coolshot 40 rangefinder has an intuitive and easy to use Continuous Scan Mode.

It has the ability to range for 8 seconds continuously.

This feature is activated by pushing the Power button which then lets the rangefinder find measurements to multiple objects.

This way you get distances to pins, trees, and hazards without ranging to them one by one.


This Nikon rangefinder can range objects anywhere from 8-650 yards which is suitable for golf.

The range distance is pretty impressive when compared to others that fall in the same price range.

Measurements are reported in ½ yard increments with an accuracy of +/- 2 ¼ feet.


Nikon, as I’ve said before, is known for its optics and they placed special emphasis on the display of the Nikon Coolshot 40 rangefinder.

The rangefinder has a LED display integrated into it which offers a whole lot more benefits than the analog CRT models LCD’s with a black display.

The LED display is crystal clear and provides reticle and distance readings in red.

This means you can even read the results while wearing sunglasses, in the rain, and varying lighting situations.

Measurements can be set to either yards or meters depending on your preference.


Nikon did not disappoint with the lenses of the Coolshot 40.

The same technology used in their DSLR products was also used here.

Multilayer castings on the lenses provide higher light transmittance.

They minimize the loss of light to give you a clear view of the target.

The lenses offer clear and sharp images of objects in the distance with an eye relief of 18.3 mm for those who wear glasses or those with less than 20/20 vision.

Together with the magnification power of 6x, you can view objects closer and ensure you are ranging to the correct object.

The magnification is not that much to reduce the field of view by very much.

In terms of lenses, I don’t think any other rangefinder comes close to the Nikon rangefinders.

Laser Technology

The Nikon Coolshot 40 rangefinder uses an invisible Class 1 laser beam.

The laser beam works at a fast rate and can hit the target and return to the rangefinder in less than a second.

The laser is highly accurate and you are guaranteed accurate measurements of your exact target.


The Nikon Coolshot 40 laser rangefinder is powered by a rechargeable 3V CR2 Lithium Battery.

This battery can last a fairly long time once fully charged.

Battery life will depend on how many rounds of golf you play each session.

The rangefinder consumes less than 1 watt for every reading which makes it one of the best on the market.

There is also an automatic shut off function that also preserves battery life.

The Nikon Coolshot 40 will automatically shut off after 8 seconds of inactivity.

The battery level indicator will tell you when it needs to charge.


The Nikon Coolshot 40 laser rangefinder design is a combination of excellent color, a nice finish, and a soft grip.

With a body made from metallic fiber covered in plastic coating, it looks and feels sturdy enough to survive a few falls perhaps.

However, try your best not to drop the rangefinder.

The look of the entire rangefinder is very cool and pleasing to the eye.

Aside from its looks, the Coolshot 40 is compact and small enough to fit comfortably in your hand, in your pocket, or golf bag when not in use.

Water resistance

The Nikon Coolshot 40 rangefinder is water-resistant and is rated IPX4 on the IP scale.

This means it is suitable for use in different weather conditions.

The rangefinder has excellent temperature tolerance and can be used in light rain or snow without worrying about damaging any of its internal components.

If you do use it in the rain, thoroughly dry the unit and store it in a cool dark place to eliminate Water condensation or mold on the lens surface due to high humidity levels.

It is important to remember that it is water-resistant and not waterproof so do not put it under running water or submerge the unit.


The Nikon Coolshot 40 laser rangefinder comes backed by a 2-year warranty.

The company states that in the event of any defects in workmanship or material, they will replace or repair the unit at no cost to you.

This warranty is valid for 2 years from the date of purchase.

  • Range:  550 yds

  • Weight: 4.4 oz

The Nikon Coolshot 20 rangefinder precedes the Nikon Coolshot 40.

It is a powerful little tool that delivers world-class performance with clean and clear optics that you would expect from Nikon.

The Coolshot 20 and the Coolshot 40 both come with a  First Target Priority Mode and a Continuous Scan Mode.

They both are compact, lightweight, versatile, and water-resistant for use anywhere at any time.

The difference in the yardage sees the Coolshot only ranging out to 550 yards with measurements in 1-yard increments.

Meanwhile, the Coolshot 40 ranges object up to 650 yards in ½ yard increments

Unlike the Nikon Coolshot 40 rangefinder, the Nikon Coolshot 20 does not come with the Hyper Read Technology.

Hyper Read technology enables the Coolshot 40 to display distance measurements faster than the Coolshoot 20.

While they share some similarities, putting them up against each other clearly saw the Nikon Coolshot 40 coming out on top.

The Nikon Coolshot 40i is the upgraded version of the Coolshot 40 rangefinder although they share many similarities.

It includes Hyper-read technology as well as First Target Priority technology and 8-second Continuous Scan Mode just like the Nikon Coolshot 40.

The Coolshot 40i can also range objects from 8-to 650 yards with 6x magnification.

It is very much like the Coolshot 40 with just a few differences.

The Nikon Coolshot 40i comes with ID technology and a Distant Priority Mode which cannot be found on the Nikon Coolshot 40.

The ID technology is for slopes and helps the user to select the proper club for uphill and downhill shots.

The slope adjusted measurement takes out all the guesswork whether it is an uphill shot over water or a dogleg with a creek running through the middle.

The Distant Priority Mode provides distance reading of the furthest targeted objects when there is a group of objects in the distance.

This is extremely useful if you have to range a flagstick through branches.

In the end, the Nikon Coolshot 40i is very much like the Nikon Coolshot 40 except for the ability to calculate slope and ranging out to the furthest target object with the Distant Priority Mode.

Since it calculates slope, the Coolshot 40i is not tournament legal like the Coolshot 40.

  • Range: 1200 yards
  • Magnification: 6x
  • Weight: 6 oz

The Nikon Coolshot Pro Stabilized Golf rangefinder copped the Best Rangefinder title in 2018 and it is well deserved.

The Nikon Coolshot Pro Stabilized comes with stabilizing technology as its name suggests.

Sometimes hands shake when using your rangefinder which can mess with your reading but with this rangefinder that is no longer an issue.

This particular rangefinder can calculate and adjust measurements based on the slopes so you can choose the right club.

The slope technology can be turned off which then makes the unit tournament legal.

It can range objects from 8-1200 yards and also comes with 6x magnification.

The Pro Stabilized rangefinder comes with an OLED display that has an auto or manual brightness setting so the user does not experience difficulties when reading the results.

Another advantage of this rangefinder is the use of next-gen HyperRead technology.

This makes the rangefinder deliver accurate readings in as little as 0.3 seconds which is faster than the Coolshot 40 at 0.5 seconds.

It is safe to say that the Coolshot Pro Stabilized rangefinder is much better than the Coolshot 40 in terms of features and technologies.

It is also waterproof and fog-proof unlike the Coolshot 40 which is simply water-resistant.

However, with the extra features, the Nikon Coolshot Pro Stabilized rangefinder costs a lot more than all of the Nikon rangefinders discussed in this Nikon Coolshot 40 review.
