In distance measurement, many people do not know what the slope value is. But once golfers master it, not only can the score be lowered, but also more fun. Now we will take you to know this.

First, the term "slope value" is used in several places in golf, such as in the handicap system. The "slope value" there usually refers to the variation in difficulty for different tees, for high handicap and low handicap players. Today, the slope we refer to is the slope in the true sense, that is, the change in height between two points. Downhill is when the height of the starting point is higher than the ending point, and uphill when the height of the starting point is lower than the ending point. On the course, we are dealing with slope from time to time, because very rarely, we hit the ball at the same height as where we landed.

But usually, we don't have to worry about such height changes, because a little height change has little effect. For most of us, it is impossible for the same club to always hit the same spot, or within a 3-meter radius. But it does not mean that we can ignore the slope.

The most obvious example is the mountain course. If you don't account for drastic changes in height, you probably won't be able to get close to the flagpole, no matter how well-played your irons are.

So how do we calculate the slope value? First, we must understand that our ball trajectory is not a straight line, but a parabola. After the ball reaches its apex in the air, it begins to descend. And on the way down, it keeps going. Depending on where it is on the slope when it hits the ground, the ball may end up 20 to 50 yards away, or 20 to 50 yards away, which is by no means a small difference in golf.

Smart golf course designers actually use this to deceive golfers. "Cheating" might be a misnomer, but it should be said that a good course designer will entice the golfer to think about whether he should play farther or closer than he actually is, and he often uses height changes to do this.

Therefore, knowing the slope value, you can choose the club accurately, and take care of your own hitting power and backspin. In other words, the slope value is an important element of hitting a good shot.

The slope value can definitely be calculated, as long as your geometry is good enough, of course, professional players can also find the most suitable shot based on feeling and experience. However, the average golfer often has a poor grasp of this issue, and does not have a lot of time to calculate, otherwise the group will be crushed.

So having a rangefinder with an incline function, such as the Besight Golf PRO XE, will help a lot. The working principle of the laser rangefinder is that the rangefinder emits a laser, the laser bounces off the target, and then returns to the rangefinder, and the rangefinder calculates the distance based on the delay time. In fact, the returning laser usually has an angle, and this angle is the key to calculating the slope value. When you turn on the slope value function, you can find two yards, one is the normal distance without slope value, and the other is the compensation distance with reference to the slope value, you can decide your own according to this value hit the ball.

At present, golf rules do not allow golfers to use the slope function of the rangefinder in formal professional or amateur games, but ordinary golfers and practice rounds can use it. In addition, the trend in recent years is to encourage simplification of amateur competitions, so the rules may be revised in the future, so it is absolutely necessary to buy a rangefinder with a slope function.
