The slope is designed for measuring the distance between you and the flagstick. And there are laser rangefinders availing this feature- which is exactly what you’re asking for. Anyways, Based on the slope you can easily calculate the right club for the play. This changes the elevation when a shot goes from one point to another that is at the same height.
Golf Laser Rangefinder
It’s a rangefinder that uses a laser beam to aim at the target to determine the distance to an object. From a rangefinder, a laser pulse is sent in a narrow beam towards an object to calculate the distance. This reflects the right away of the target and returned to sender.
Though, to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements. Some laser rangefinder includes an internal ‘inclinometer’ which can determine the slope of your target area.
How Does a Golf Rangefinder With Slope Work
Simply put, first, the rangefinder will shoot a straight line to the flag. Then it will scan the area and take into consideration the angle at which you are aiming the rangefinder. This way, it will be able to calculate the actual horizontal distance needed to reach the flag.
What Does a Laser Rangefinder With Slope Do
Its job is to take the elevation into account while shooting. You may calculate the small number of yards for yourself but the height will tell you otherwise. Because the difference in elevation does not mean that the slope from you to the hole is only a few yards!
First, you need to know the slope from you to the hole. After this, you can figure out just what type of club to use and how much pressure is needed to hit the ball. You will also be able to know how hard to swing for the shot.
This is where a rangefinder with a slope comes for rescue. You do need to calculate every equation by yourself; the rangefinder can give you an adjusted distance to shoot for. This adjusted distance is what we need to choose a club or know how hard to swing.
The rangefinder with scope will give you two types of readings. One is the actual distance to the hole and the second, an adjusted slope distance to the hole. It’s all based on the rangefinders calculation.
Do I Need a Rangefinder With a Slope for Golf?
It actually does work like magic for a regular player. The importance of having a golf rangefinder with slope heavily depends on your playing ability though. You can practice using a slope rangefinder every day and improve your score, but if you’re a newbie then there are still other things to learn like, the right club, how to hit properly, etc.
With all of that being said, a rangefinder with slope does the all calculation for you so you can spend more time adjusting your swing. After having a general idea of the true distance between you and the flag, also taking into consideration the slope, it can help you save dozens of strokes by the end of your game.
This only works if you play on hilly courses. Otherwise, playing on a flat course will not factor in much slope at all because it all depends on elevation.
Slope in competitions?
According to Appendix IV of Rule 14-3, no measuring device that calculates for slope may be used during tournament play. Both USGA and R&A have updated it by 2016. So, you can use a rangefinder that calculates the distance, but not with a slope because it is illegal.
However, it seems common in local rules permitting golfers to use them in tournaments although it depends on the level of competition.
How Important Is Rangefinder Golf With Slope
You calculate the distance between you and the scope; it’s a straight line. But after hitting the ball you will realize, the hit wasn’t in a straight line. That’s why you have to consider for slope. Behind the math is that the ball is to be hit at an arc and with a trajectory that affects how far it actually goes.
After your shot hits its peak, it begins to fall. And as it falls it continues to move forward. Sometimes your shot may get affect anywhere from 25 to 50 yards, depending on the slope of the land.
A small trick
A smart course architect actually uses this effect to trick the golfer. It is part of a good golf course design to let the golfer thinking that he needs to hit it further or shorter. This trick is usually done with subtle changes in elevation.
Therefore, knowing the slope at which you are hitting the ball is a very critical move for determining club selection, velocity, and spin. In other words, now you will get satisfied for hitting a good shot!
Another thing is that you will find changes in elevation between you and the pin. This is impossible to notice with the naked eye. Balls will travel a shorter distance with uphill slope and a farther distance with downhill slope.
Judges find slope with a rangefinder illegal in an official tournament and are grounds for immediate disqualification. Professional golfer uses a rangefinder to measure distances on flat ground rather than with obstacles in the way. The main difference between the two units will be that one does not consider changes in elevation into account while the other does.
Q: How much do these cost?
Ans: I would say around the $250 to $500 range. The lower price of a rangefinder is pretty much solid but the highly-rated rangefinders come with many features. I found Precision Pro NX9 laser rangefinder and TecTecTec ULT-X golf rangefinder to be cool enough to add to your golfing arsenal.
Q: How is the battery life?
Ans: The battery life can last five months to a year. However there are some companies like Precision Pro, offer free batteries for life if you register online.
Q: How many yards are covered in on pin?
Ans: The rangefinder only locks in on a pin inside 150 yards.
Basically, you can practice with a slope; this will help you to get better at playing golf. But there is no need to buy if you only enjoy playing golf with friends. But having a slope in a laser golf rangefinder is beneficial to a player. But then again, you can buy countless gadgets that will help you, but it all comes down to your own skill level.
