How To Choose The Best Golf Rangefinder
If you need help figuring out which golf rangefinder is right for you, read our in-depth article How To Choose The Best Golf Rangefinder.
It will help you understand what rangefinder features are available, how they work, how you can identify what type of rangefinder you need, and ultimately how to choose the best golf rangefinder for yourself.
How Rangefinders Work
A laser rangefinder is a device that uses laser technology to measure distance. By bouncing a laser off of an object and measuring the time it takes for the laser to return, the rangefinder can calculate the distance to the object.
Laser rangefinders are used in a variety of applications, including surveying, navigation, and of course golf.
TECHNICAL EXPLANATION OF HOW A LASER RANGEFINDER WORKS The laser rangefinder works by sending out a laser pulse and measuring the time it takes for the laser to bounce back off the object. The laser rangefinder then uses the formula: Distance = (Speed of Light * Time) / 2 to calculate the distance to the object. The speed of light is a constant, so by knowing the time it takes for the laser to bounce back, we can calculate the distance.
How Does The Slope Function Work On A Golf Rangefinder?
Now that we know how laser rangefinders work, let’s take a look at how they are used in golf. Laser rangefinders are becoming increasingly popular among golfers because they can help you make more accurate shots.
Most laser rangefinders on the market today come with a feature called “slope.” Slope compensates for the elevation change between you and the flagstick.
TECHNICAL EXPLANATION OF HOW SLOPE IS MEASURED The slope function on a golf rangefinder measures the angle of incline or decline between the player and the target. Most golf rangefinders with a slope function use a built-in inclinometer to measure the angle of the slope. The inclinometer works by using a small accelerometer or other type of sensor to measure the force of gravity on the rangefinder. By knowing the angle of the slope and the distance to the target, the rangefinder can then calculate the adjusted distance that the player needs to hit the shot based on the slope.
For example, let’s say you are standing on a hill and looking down at the flagstick. The laser rangefinder will give you the distance to the flagstick, but it will also take into account the fact that you are standing on a hill.
This is where slope comes in. Slope will give you the adjusted distance to the flagstick, taking into account the elevation change.
Slope is a great feature to have if you are playing on a course with a lot of elevation changes. It can help you make more accurate shots and lower your score.
The Downsides to Using Slope Functionality
There can be a few drawbacks to using the slope functionality of a rangefinder, but they are limited to tournament play.
Firstly, you can become over reliant on it to provide the true distance to a target. While this works great in non-tournament play, you could struggle in tournaments if you can’t figure this out without the slope function turned on.
Ideally, you use the slope function in a practice round and note elevation adjustments in a yardage book. This would help you overcome this limitation and over time you should develop a sense of how uphill/downhill shots paly.
Secondly, if you forget to turn off the function in a tournament you will likely be disqualified. This is unlikely, but still something to consider if you play a lot of tournament golf.
The top slope rangefinders all have visual indicators that show slope is turned off.
Laser Rangefinders vs GPS Devices
Whether you want a rangefinder or GPS device, there is no wrong answer as to which device is better. Many players carry both devices to get the advantage from each.
There are a few key advantages that a golf laser rangefinder has over a golf GPS device.
First, laser rangefinders are generally more accurate than GPS devices. This is because they use laser technology to measure distance, while GPS devices use satellite technology. This means that laser rangefinders can be more accurate in measuring distances to the flag, hazards, and other objects on the course.
Second, laser rangefinders don’t require a satellite connection in order to function. This means that you can easily carry a laser rangefinder with you on the course, and don’t have to worry about losing a GPS signal. Occasionally satellite reception might be limited which leads to inaccurate yardages.
On the other hand, GPS devices can be attached to your bag, or worn on your wrist providing real-time yardage updates. With GPS, you always see a visual of the hole with yardages to hazards, the green and any target you wish.
Hybrid Laser Rangefinder/GPS
Manufacturers also realized the tradeoff between GPS devices and laser rangefinders so they came up with an innovative idea; laser rangefinders with GPS functionality built-in.
These rangefinders incorporate GPS in (2) different ways:
- External display built into the rangefinder
- Internal display with overlaid visuals in the viewfinder
External Display
This innovative design incorporates an external display built right into the rangefinder body.
You get the benefits of a GPS unit and rangefinder with slope. This means hole overviews, hazards, layup distances, green views and more.
Some units also include the undulations on greens.
A Unit incorporating this design:
Internal Display
This design is different in that the GPS features are seen when looking through the viewfinder.
The visuals are overlaid on the actual hole you are looking at.
This shows you what hazards are in play around where you are aiming (via the range arc).
Units incorporating this design are:

The Voice Caddie CL2 Rangefinder includes what they call “Speed Detecting Booster”.
This means that it can lock onto targets extremely fast.
Compact Form Factor
The CL2 is very compact unit and is almost 3 oz. lighter than the SL2
Manual Focus Ring
You can quickly adjust your focus using the external manual focus ring.
Optics
The Voice Caddie TL1 has special high-clarity, anti-glare optics. The rangefinder can track targets at 700 yards. You will never use that range, but it means it will have no problem at 250 yard targets.
In addition, it has a external manual focus ring (on the viewfinder) to quickly adjust the focus to your eyes and conditions.
RANGEFINDER OPTICS & DISPLAY The display on a laser rangefinder is typically separate from the optics and is used to present the measured distance to the target. The optics on a laser rangefinder are used to gather light from the target and focus it onto the laser detector, which is responsible for measuring the distance to the target. The optics typically consist of a series of lenses and prisms that are used to focus the laser beam and improve image clarity. The quality of the optics can have a significant impact on the accuracy and overall performance of the rangefinder.
Display
The Voice Caddie CL2 Rangefinder‘s internal display (meaning the numbers that are displayed when you look through the viewfinder) is 2-color OLED.

Pairing a Rangefinder with a Launch Monitor
When you pair a launch monitor (such as the Bushnell Launch Pro) with a laser rangefinder, you are eliminating variables from your golf game–which is good! A launch monitor can help you dial in your exact distances for each club.
When you pair that with the on-course precision of a laser rangefinder, you take the guesswork out of each shot. You can then focus on the target and executing your best swing.
So, if you’re serious about improving your golf game, a laser rangefinder with slope is worth considering. By helping you get a better understanding of the course and making it easier to execute shots, a rangefinder can help you take your game to the next level.
Pair this with a launch monitor where you can dial in your exact distances, and you will be playing the best golf you are capable of.
See our page on Launch Monitors for reviews of the best models.
