Overview
Callaway's 300 Pro+ is a golf laser rangefinder with an OLED display, USB-C rechargeable battery, pulse pin-lock feedback, and a slope mode with an external on/off indicator light for tournament legal play.
The two features that separate this from a basic rangefinder are the pulse pin-lock vibration, which confirms a flag lock rather than a tree or cart behind it, and the external slope LED, which lets a playing partner or official see at a glance whether slope-adjusted yardages are switched on. Both address real complaints golfers have with cheaper units: false locks and being unsure if slope is legally disabled during a tournament round.
- High-res two-color OLED display
- Pulse pin-lock confirms flag lock
- Slope mode with external LED indicator
- 5 to 1,200 yard range, 7x magnification
Who it's for
Suits golfers who play both casual rounds with slope-adjusted numbers and sanctioned events where slope must be visibly off. Less relevant for players who only need a basic straight-line yardage and don't care about tournament rules.
Pros and cons
- Pulse vibration confirms flag lock over background objects

- USB-C rechargeable, rated 30+ rounds per charge
- Integrated magnet for cart mounting
- No rating or review data available to verify real-world accuracy
- Battery life figure is a typical-use estimate, not guaranteed
Performance notes
