Accuracy & Performance
Accuracy is a strong suit of the Series 4 Ultra. Yardages are consistent and repeatable, with readings lining up closely across multiple scans of the same target.
In real-world play, distances feel trustworthy from tee shots through approach shots, and performance compares favorably with other rangefinders in the $300 range.
Speed & Target Acquisition
Target acquisition is quick and confident. The Series 4 Ultra locks onto flags efficiently and provides clear vibration feedback once the pin is captured.
Background filtering is solid, helping the unit isolate the flag even when trees or bunkers sit behind the target. Lock-on speed feels responsive and polished.
Optics & Display Quality
The Series 4 Ultra features 6x magnification paired with a high-contrast OLED display, which makes yardages exceptionally easy to read in a wide range of lighting conditions. Whether playing in bright sunlight or lower-light situations, the OLED screen delivers crisp numbers with excellent contrast against the background.
Optical clarity is strong for this price point. While it may not match ultra-premium tour-level glass, the combination of solid optics and an OLED display gives the Series 4 Ultra a noticeably more refined viewing experience than many similarly priced competitors.
Magnet & Mounting Convenience
A built-in cart magnet comes standard and holds securely to cart frames throughout a round.
This is a practical, everyday feature that adds convenience and helps keep the rangefinder easily accessible between shots.
Slope Technology
Slope-adjusted distances are applied automatically once the target is locked, helping golfers account for elevation changes with confidence.
Slope can be toggled on or off directly on the unit, keeping the Series 4 Ultra flexible for different playing situations without adding complexity.
Build Quality, Ergonomics & Design
The Series 4 Ultra has a refined, premium feel in hand, with a balanced weight and comfortable grip. The housing feels durable, and overall fit and finish are excellent.
From a design perspective, Blue Tees continues to set itself apart. The Series 4 Ultra is available in several sharp colorways, and the navy option in particular looks clean, modern, and noticeably more stylish than the traditional black-and-gray designs common in this category. It’s easily one of the best-looking rangefinders we’ve tested.
Controls are intuitive and easy to operate, contributing to a polished user experience.
Battery & Power
The Series 4 Ultra is powered by a CR2 battery, and Blue Tees includes three batteries with the unit. This provides long-term convenience and minimizes the need for immediate replacements.
Value & Alternatives
At $299, the Blue Tees Series 4 Ultra sits squarely in the midrange category and offers a well-rounded feature set for the price. When you factor in slope functionality, fast pin locking, a built-in cart magnet, strong optics, and an OLED display, the value proposition is especially compelling.
Golfers who want rechargeable batteries or the lowest possible price may look at other Blue Tees models like the 3MAX+, while those seeking tour-level optics may spend more. For golfers looking for a premium feel without premium pricing, the Series 4 Ultra is a strong middle-ground option — especially with the available discount.
