The compression of a golf ball is a measure of its density or hardness. It is determined by how much the ball compresses when it is struck by the clubface at impact. The compression of a golf ball is measured in units of pounds per square inch (PSI).

The Pro V1 golf ball is one of the most popular golf balls on the market, and it is made by the company Titleist. Titleist uses a proprietary process to create the Pro V1, which includes a multi-layer design with a soft cover and a high-energy core. The compression of the Pro V1 golf ball is an important factor in its performance on the course.
The compression rating of a Pro V1 golf ball varies depending on the specific model and year of production. However, the typical compression rating of a Pro V1 golf ball is between 70 and 90 PSI. This is considered a medium to high compression rating for a golf ball.
A higher compression rating typically results in a ball that is harder and more resilient, which can lead to greater distance and less spin. However, a higher compression rating can also make the ball more difficult to control and reduce feel around the greens.
Conversely, a lower compression rating typically results in a ball that is softer and more responsive, which can lead to greater spin and control. However, a lower compression rating can also reduce distance and make the ball more susceptible to wind.
Titleist offers a range of Pro V1 golf balls with varying compression ratings to suit different player preferences and skill levels. For example, the Pro V1x golf ball has a higher compression rating than the standard Pro V1, which can lead to greater distance and less spin. However, the Pro V1x may not offer the same level of feel and control around the greens as the standard Pro V1.
Ultimately, the compression of a Pro V1 golf ball is just one of many factors that can affect its performance on the course. Other factors include the ball’s dimple pattern, cover material, and overall design. Golfers should experiment with different types of golf balls to find the one that works best for their game and individual preferences.
