In this review of the X1-660 Golf Rangefinder the reviewer finds it best suited for golfers and hunters who want a compact, accurate distance tool with modern conveniences. The bottom line is that the X1-660 delivers reliable yardage, quick measurements and a rechargeable battery that lasts for thousands of reads, making it a practical choice for players who value portability and easy upkeep. Its slope compensation and flagpole lock are the single biggest reasons to buy if you need angle-adjusted yardages and a clear lock on distant flags.

Key Features

• High-precision distance: The X1-660 measures from 3 to 660 yards with claimed 1 yard accuracy, giving dependable yardage for club selection.

• Rechargeable battery: A 750mAh lithium-ion cell with Type-C charging supports long runtime and is rated for roughly 20,000 measurements per full charge.
• Functional targeting modes: Continuous scan, flagpole lock, horizontal and vertical distance and speed measurement provide a versatile set of measurement options.

Who It's For

The X1-660 is ideal for recreational and competitive golfers who need slope-compensated distances and want a compact, easy-to-carry rangefinder. Hunters and bowhunters who require a quick vibration confirmation and long measuring range will also find the unit useful in the field.
