Introduction
- When the machine is powered off, it is a precision optical telescope. Observe the target via eyepiece and adjust knob until the target is clear. It offers extremely fast acquisition and ±0.5-yard accuracy. it has a magnetic stand on the side, which allows you can easily mount the device on the cart bar

Mode 1. Tour Mode

- Power on.
- Select the target object and aim the target.
- Press the “ ” Button to measure.
- The data will be displayed on the screen

Mode 2. Slope Mode
- After powering on, press the Slope Button to Slope Mode. Slope mode has golf compensated distance, it can easily help golfers to get
compensated distance when they want it. In this mode, you will see a logo ” ” appear on the display.

- Power on.
- Press the Slope Button.
- Select the target object and aim the target.
- Press the “ ” Button to measure.
- The data will be displayed on the screen.
Slope Principle:
- AC distance is 160 yards. AB distance is also 160 yards, although it is on a slope with a 6% grade. If a golfer were to play the B hole as 160 yards, the ball would fall to C via D.
- Due to the slope, it should be played as an AE 168-yard shot. AE 168 yard is played as distance based on slope.

- When the slope is positive, the hitting distance should be bigger than the Straight-Line Distance.
- When the slope is negative, the hitting distance should be less than the Straight-Line Distance.
Flagpole Lock & Vibration
- Keep pressing and aiming around the flag or across from the background to the flag. The LCD shows different data until the flagpole locks and vibrates.

REVASRI H3D Golf Rangefinder with Magnet-FAQs
Does the REVASRI H3D rangefinder have a magnetic mount?
Yes, the REVASRI H3D comes with a built-in magnetic mount, making it easy to attach to metal surfaces like golf carts for convenient access.
How do I use the REVASRI H3D rangefinder?
Press and hold the Power button to activate scanning mode. Aim at the background and move towards the flag. When the flag is locked, the device will vibrate. It supports slope compensation and can lock onto flags up to 250 yards away.
How do I aim the rangefinder correctly?
Simply point the rangefinder at the flag and press the top button. It measures the time it takes for a laser beam to bounce back from the target to calculate the distance accurately.
Can magnets damage a rangefinder?
Yes, extremely strong external magnets (like industrial types) can interfere with a rangefinder’s electronics. Use only built-in or compatible magnetic mounts to avoid malfunction.
How does the REVASRI rangefinder work?
It uses a laser time-of-flight system, sending a pulse toward the target and measuring how long it takes to return, giving you precise distance measurements.
Why isn’t my rangefinder showing distances?
Possible reasons include using it indoors, aiming through glass, measuring beyond its range, or interference from rain, fog, bright light, or dust.
Can I use my smartphone as a golf rangefinder?
Yes, there are mobile apps like Motocaddy that offer GPS-based golf rangefinding using extensive course databases.
How does a manual rangefinder differ?
Manual rangefinders require you to align two images manually to measure distance. They don’t use lasers and are typically slower and less precise.
