Understand Your Device
Before you start using your rangefinder on the course, it's essential to understand its features and functions. Most rangefinders come with different modes for measuring distances, such as slope-adjusted measurements or pin-seeking mode, which help you measure the distance to the flagstick more accurately. Leupold golf rangefinders even come with Prism Lock to help you locate the flagsticks that utilize prisms for accuracy. Familiarize yourself with your device's modes and settings, and make sure you know how to use it before heading out to play.

Use It on the Range
Using a rangefinder on the range can help you understand how far you hit each club and adjust your game accordingly. Measure the distance to different targets, and try hitting balls with different clubs to see how far they travel. This information can help you determine the club to use on the course and help you make better decisions about which shots to play.

Check Your Yardages
Once you're on the course, use your rangefinder to measure the distance to various points, including the flagstick, hazards, and other landmarks. Knowing the exact yardage to the target can help you make better decisions about which club to use, and which shot to play. It can also help you avoid hitting hazards and other trouble spots on the course.

Check for Slope
Many rangefinders come with slope-adjusted measurements, which take into account the slope and elevation changes on the course. This feature can be especially useful on hilly or undulating courses, where shots may play shorter or longer than the actual distance. Use the slope-adjusted measurements to get more accurate yardage to the target and adjust your shot accordingly.

Check the Weather
Weather conditions can have a significant impact on your shots, and using a rangefinder can help you adjust for wind and other factors. Use your rangefinder to measure the distance to the flagstick and other targets, and then check the wind direction and strength to determine how it will affect your shot. This information can help you choose the right club and make better decisions about which shot to play.

Stay Focused
While using a rangefinder can be helpful, it's important to stay focused on your game and not get too distracted by the technology. Use your rangefinder quickly and efficiently, and then put it away to focus on your shot. Remember, golf is a game of precision and focus, and using a rangefinder is just one tool to help you achieve better results.
