Callaway 300 Pro Golf Laser Rangefinder Ltd Edition Quantum — 6x Magnification, Slope & Pin-Lock

The Callaway 300 Pro Golf Laser Rangefinder (Ltd Edition Quantum) is a 6x magnification, slope-capable laser that delivers yardage to +/−1 yard with pin-locking P.A.T. and cart-mounting convenience.

Designed to give golfers reliable distance data without fuss, the Callaway 300 Pro combines accurate slope compensation, high magnification, and tactile confirmation so you can choose the right club and read tricky yardages quickly. Its external slope on/off switch keeps the unit tournament-legal when needed, while the Pulse confirmation and strong magnetic mount make it practical from tee to green.

How does the Callaway 300 Pro improve yardage accuracy on uneven courses?

The 300 Pro’s Slope Technology measures the angle of incline or decline and calculates a slope-adjusted distance so you get a more realistic playing yardage for uphill and downhill shots. You can toggle slope on or off with a visible external switch to meet competition rules.

• Slope-adjusted distances for elevation changes
• External switch to enable/disable slope mode quickly
• Measures in yards or meters to suit course preferences

Can I lock onto the flag even with background clutter?

Yes — Pin Acquisition Technology (P.A.T.) helps you identify and lock onto the flagstick, even when trees or objects sit behind it. When the laser secures the pin, a short vibration pulse confirms the lock so you won’t second-guess the reading.

• P.A.T. works up to 300 yards for pin targeting
• Pulse vibration confirms when the laser locks the flag
• Reliable performance in varied course backgrounds

What are the optical and measurement specifications I should know?

The 300 Pro offers 6x optical magnification and an effective measuring window from 5 to 1,000 yards with ±1 yard accuracy, giving you confidence for short approaches and long-range line-of-sight shots. Switch between yards and meters depending on your local course setup.

• 6x magnification for clearer target viewing
• Range: 5–1,000 yards with ±1 yard accuracy
• Selectable units: yards or meters

How does the 300 Pro fit into on-course routine and gear setup?

The 300 Pro is built for quick access and durability: a molded hard carry case protects the unit, an elastic connector speeds looper attachment, and an integrated magnet secures the rangefinder to a cart frame. Its external controls keep slope functions visible and simple to change between rounds.

• Included molded hard carry case for protection
• Elastic band connector for rapid attachment on carts or loopers
• Magnahold cart mount for secure, hands-free storage during play

Who is this for? The Callaway 300 Pro Ltd Edition Quantum is aimed at golfers who want fast, dependable distance readings with tournament-legal flexibility. It suits competitive players needing a quick slope toggle, weekend golfers who appreciate pin-lock confidence, and anyone who values a compact, durable rangefinder that keeps pace with real course conditions.
