How to use

   Power On the Device
Hold the main power button for two seconds to turn on the rangefinder. The display will activate, and the unit will be ready for measurement.

   Aim at Your Target
Look through the viewfinder and center the crosshair directly on the flag or your desired target. Ensure you’re steady and facing the pin for the most accurate reading.

   Lock the Distance
Press the power button once while aiming. The rangefinder will quickly calculate the distance and provide a vibration confirmation once it locks onto the flag. The yardage will appear clearly on-screen.

   Use Slope Mode (Optional)
Toggle slope mode on or off using the side button. With slope enabled, the device will automatically account for elevation changes — helping you select the right club based on adjusted distance.

   Recharge When Needed
Connect the included USB charging cable to a standard outlet or portable charger. A full charge supports multiple rounds, ensuring you're always ready to play.

Pro-Level Accuracy, Made Effortless.

No more guessing or second-guessing you shot

 

With FlagSeek's advanced Pin Sensor Technology that instantly detects and locks onto the flag — even when it’s surrounded by trees or overlapping backgrounds. Simply aim, press, and scan across the landscape. As soon as the rangefinder locks onto the pin, you’ll feel a short vibration confirming accuracy. Both straight-line and slope-adjusted yardages are displayed on screen in clear, easy-to-read detail. 

 

Whether you're playing a flat par 3 or navigating elevation changes, you’ll get fast, trusted measurements every time — no second-guessing required.

Title

Conquer Every Course with Slope Adjusted Precision + Vibration Lock!

FlagSeek’s integrated slope technology automatically calculates both the straight-line and elevation-adjusted distance to your target. When slope mode is enabled, the rangefinder compensates for uphill or downhill angles—giving you a more accurate “plays like” yardage so you can make smarter club choices and swing with confidence. With slope turned off, you’ll get true distance readings that are legal for tournament play. 

 

Seamlessly switch between Slope On and Slope Off with a single press of the side button—no complicated menus or setup required. Once you’ve locked onto the target, the device provides a gentle vibration to confirm accuracy, giving you instant confidence in your yardage before every shot.

Tired of Shakey measurements and background interference?

Unlike basic rangefinders that struggle with busy backgrounds, FlagSeek uses intelligent scanning to detect the pin even when it overlaps with trees or slopes. Just hold the measurement button to activate continuous scan mode, sweep across the target area, and let the rangefinder do the work. Once it locks onto the flag, you'll feel a subtle vibration, the icon flashes, and your slope-adjusted yardage is displayed instantly — no guesswork, no hesitation, just total shot confidence.
