Callaway Laser Rangefinder 300 Pro Slope — 6x Magnification, Slope Compensation & Pin-Lock

The Callaway Golf 300 Pro Slope Laser Rangefinder is a compact, 6x magnification laser device that measures distances from 5 to 1,000 yards with slope compensation and pin-locking confirmation.

Designed for golfers who want quick, reliable yardages on every shot, the 300 Pro combines slope-adjusted distance readings, pin acquisition technology (P.A.T.) with a tactile confirmation pulse, and a rugged, cart-ready build. It reads in yards or meters with +/-1 yard accuracy, includes an on/off slope switch to meet tournament rules, and ships with a molded hard case and carabiner for secure storage and transport.

How does slope mode change my distance readings?

The 300 Pro’s Slope Technology measures the angle between you and the target, then calculates an adjusted distance that accounts for uphill or downhill elevation. Use the external switch to turn slope on for practice or casual rounds and switch it off when you need tournament-legal yardages.

• Automatically computes incline/decline-adjusted distance
• External on/off slope switch for easy legal compliance
• Reads and displays in yards or meters
• Recommended for shots with significant elevation change

Can I lock onto the pin reliably from a distance?

Yes — Pin Acquisition Technology (P.A.T.) helps isolate the flagstick from background clutter so you can lock the laser on the pin up to 300 yards away. When the unit locks on the target, a short vibrating pulse confirms the reading so you can be confident before you pick a club.

• P.A.T. distinguishes the pin from trees and objects behind it
• Pulse confirmation vibration verifies a successful lock
• Effective pin locking up to 300 yards under typical conditions
• Quick, repeatable readings for faster shot planning

What accuracy and magnification can I expect on course?

The Callaway 300 Pro uses 6x magnification to bring targets into clearer view and delivers distance readings accurate to +/- 1 yard across a 5–1,000 yard range. The optics and measurement precision work together so you get dependable numbers whether you’re measuring a close approach or a long carry.

• 6x optical magnification for sharper target visibility
• Measurement range: 5 to 1,000 yards with +/-1 yard accuracy
• Choice of yards or meters display settings
• Compact size for handheld use or pocket storage

How does the 300 Pro fit into my bag and routine?

The 300 Pro is built for everyday play: a magnetic mount secures it to a cart frame for quick access, and the included premium molded case with carabiner and elastic quick-close band protects the unit between shots. US units include a battery so the rangefinder is ready to use right out of the box.

• Integrated Magnahold magnet for cart attachment
• Durable molded hard case with carabiner for storage
• Elastic band connector for rapid engagement while walking
• Battery included in US-packaged units

Who is this for? The Callaway Golf 300 Pro Slope Laser Rangefinder is aimed at golfers who want reliable, tournament-compatible technology with the flexibility of slope-assisted readings. It suits serious amateurs and club players who value quick pin-locks, accurate measurements across a long range, and practical accessories like a cart mount and protective case. If you need straightforward, repeatable yardages with options for competitive play, the 300 Pro is built to deliver on-course confidence without complicated setup.
