Callaway Golf Laser Rangefinder 300 Pro Slope with Pin-Lock Vibration

The Callaway Golf 300 Pro is a golf laser rangefinder for choosing distances on the course, with 6x magnification and slope-adjusted measurements.

• Measures from 5–1000 yards (4.6–914.4 m) with +/- 1 yard (0.9 m) accuracy — gauge distances across a wide range of on-course shots.
• P.A.T. locks onto the pin from up to 300 yards (274.3 m) — target the flag even when trees or other background clutter are present.
• Pulse confirmation gives a short vibration when the laser locks onto the pin — know when the target distance has been confirmed.
• External Slope On/Off switch — disable slope mode for tournament play.
• Integrated cart magnet and molded hard carry case — keep the rangefinder accessible on a cart and protected when carried.

Golf shots often involve more than the straight-line distance to a target: a bunker may need to be carried, or a green may sit above the player. The Callaway Golf 300 Pro is made to help golfers measure a target and account for elevation while making on-course club and aim decisions. Its functions also support pin targeting, access from a golf cart, and carrying the unit between shots.

How does the Callaway Golf 300 Pro account for slopes?

The Callaway Golf 300 Pro measures the angle of an incline or decline and calculates a slope-adjusted distance. This provides an elevation-aware distance reading for shots such as carrying a fairway bunker or aiming at an elevated green. Use the external switch to turn slope mode on or off; with slope disabled, the rangefinder is legal for tournament play. The rangefinder measures in either yards or meters, so golfers can use their preferred distance unit.

• Slope Technology accounts for elevation changes in the measured distance.
• The external switch visibly indicates whether slope is enabled or disabled.

How does it confirm a reading on the pin?

Pin Acquisition Technology (P.A.T.) helps the Callaway Golf 300 Pro lock onto the flagstick, including when trees or other clutter appear behind it. When the laser locks onto the pin, the Pulse feature produces a brief vibrating burst to confirm the target distance. The 6x magnification supports viewing the target through the rangefinder while aiming.

• Pin-locking technology is designed for flagstick targeting, rather than relying only on the surrounding background.
• The vibration is a confirmation signal delivered when the laser locks onto the pin.

What comes with the Callaway Golf 300 Pro, and how can it be carried?

The Callaway Golf 300 Pro comes with a molded hard carry case, a carabiner, and an elastic quick-close band. The case provides a dedicated way to carry and protect the rangefinder, while its elastic band is designed for faster access during play. A strong integrated magnet lets the rangefinder attach to a golf cart frame for convenient access while playing.

• The carry case has a molded hard construction and includes a carabiner.
• The elastic band is designed to make the case quicker to engage during play.
• Units sold in the United States include a battery.

The Callaway Golf 300 Pro suits golfers who want slope-adjusted distance readings, pin-lock confirmation, and a rangefinder that can be mounted on a golf cart or carried in its included case. Its external slope control also accommodates tournament play when slope mode is switched off. For golfers making distance decisions around elevation changes and aiming at the flag, it combines slope measurement, pin targeting, and practical on-course access in one unit.
