Performance

Accuracy & Range

The Callaway 300 Pro boasts an impressive ±1-yard accuracy, making it one of the most reliable rangefinders in its class. In testing, it consistently provided precise measurements up to 400 yards, with the ability to detect flags up to 300 yards using P.A.T. Beyond that, it can measure general distances up to 1000 yards, though most golfers won’t need that range.

Slope Functionality

The slope-adjusted distance feature is a game-changer for hilly courses. It calculates the angle of incline/decline and adjusts the yardage accordingly. This helps golfers select the right club without manual calculations. The external slope switch makes it easy to disable for tournament compliance.

Pin-Locking & Pulse Confirmation

The P.A.T. technology works exceptionally well, even with obstacles like trees or bunkers in the background. The pulse vibration is a subtle but effective confirmation that you’ve locked onto the flag, eliminating guesswork.

Magnahold Magnet & Portability

The built-in Magnahold magnet is strong enough to securely attach the rangefinder to a golf cart’s metal frame. This is a huge convenience compared to models that require separate mounts. The compact size (fits in a pocket) makes it easy to carry.

Weather Resistance

Golfers frequently play in varying conditions, and the 300 Pro holds up well in rain and fog. The water-resistant casing ensures durability, though it’s not fully waterproof (avoid submerging it).

Battery Life

The CR2 battery provides long-lasting performance, but since it’s not included, users should keep a spare.
